OVERVIEW
Who
We A re
F r o m D a y O n e : L i s t e n i n g t o t h e C u s t o m e r. In August 1927, brothers Arthur and Kirby Pennick of Houston founded Oil Center Tool (O-C-T) to produce pump liners and rods for the oilfields of East Texas. In 1930, O-C-T introduced a new type of casing head and tubing head that was an immediate success. ➤ O-C-T soon followed these innovations with another first. At the time, completion wellheads (Christmas trees) were assembled and tested on-site – an expensive, time-consuming and dangerous practice. O-C-T had a better idea, along with better completion wellhead components. The company introduced the first factory-assembled and tested Christmas tree, an innovation hailed as a landmark in efficiency, safety and cost-effectiveness. ➤ After only a few years of operation, O-C-T was on its way to setting the standard for the design, manufacture and service of the surface wellhead. The Our Company at a Glance

➤ Elastomer SEAL TECHNOLOGY
Higher pressures, well-treatment chemicals, hotter production and longer frac times accelerate the wear and tear on seals, reducing useful life. And if one seal in a wellhead fails, it can blow the budget with lost production and workover time.
Seals Conventional O-ring elastomer seals no longer meet the industry’s stringent design and safety criteria. FMC Surface Wellhead has developed seals that compensate for thermal expansion and contraction, and the larger API casing and tubing tolerances that create increasingly difficult sealing conditions. At the same time, we’ve developed proprietary new elastomers suited to the design parameters of the new FMC Surface Wellhead seals, providing the best combination of mechanical properties and chemical resistance. We design and manufacture our elastomer seals.

Anywhere in the world, in applications ranging from mature low-pressure oilfields of West Texas to critical-service environments from the North Slope to the China Sea, FMC Surface Wellhead is the first name in gate valve technology. We are continually adding value to our superb family of gate valves by listening to your needs, applying engineering improvements to our proven products and making them more cost-effective.
FMC Surface Wellhead offers all Model 100 Series Valves in independent loosevalve configurations for wellhead, tree and manifold applications. Model 100 series valves can also be supplied in composite block configurations for tree and boarding valve applications to suit customer’s special applications and requirements.

➤ Metal-to-Metal
Seals Our oilfield customers look to metal seals as cost-effective technology for extending service life and improving production efficiency. In general, metal seals last longer and provide more reliable service, especially in critical applications. FMC Surface Wellhead’s patented “bump” metal seal is regarded as the technological breakthrough in metal seals for wellheads. We manufacture both self-energized, straight-bore, metal seals and externally energized seals.

FMC KONGSBERG SUBSEA:
SHARED TECHNOLOGICAL ADVANCES
FMC Surface Wellhead was born on land and migrated to the sea. As FMC Energy Systems grew and expanded, the organization was restructured to concentrate like technologies and services into nine highly specialized operating units, including FMC Surface Wellhead. Our sister enterprise, FMC Kongsberg Subsea, which is number one in its global market, grew partly out of the original FMC/OCT wellhead technological group. Today, FMC Surface Wellhead and other FMC Energy Systems operations and their customers benefit from the technology advances developed by FMC’s Energy Systems subsea unit, developing drilling and completion systems for seabed wells, the most hostile of environments for oil and gas production. A notable example, our C22-EG Casing Spool. Its bowl protector retaining subsea technology doesn’t need costly lockdown screws, increasing safety by eliminating the need to work under BOP and potential leak path.

OVERVIEW

Standard o Custom The FMC Surface Wellhead Product Line: Standard Flanged Wellheads to Custom-Engineered Systems
Our company is proud to be recognized for its history of technological innovation and its reputation for custom-engineered drilling and completion wellhead systems. But that’s only a narrow slice of what FMC Surface Wellhead offers: In 75 years of listening to your industry, our company has developed a broad spectrum of wellhead drilling and completion components, systems and services. Our C-22 casing head components, for example, introduced in 1962, quickly became the industry standard for this class of product and remain in high regard among company men, drilling engineers and crews, even as we continue to improve and enhance this outstanding line.
For our customers, this broad range of solutions translates into the convenience of relying on a single source – FMC Surface Wellhead – to supply you with exactly what you need for your application, no matter what it is, where it is, how routine or how challenging. For many wells, a standard flanged API wellhead rated at 2,000 psi is the best choice for the budget and risk parameters. For deep critical-service
wells, reliability is the driver: a customengineered project approach may be the best solution. As location, depth, pressures, number of completions per well and other factors complicate the scope, hazards and degree of difficulty of a project, FMC Surface Wellhead is there with a solution that optimizes performance and minimizes your total well cost.

We are proud that our safety record outperforms the industry. The stats back this statement: FMC Energy Systems’ Houston facility, for example, logged 7.4 million man-hours without a lost-time incident. FMC Technologies accepts the responsibility to protect the environment and the health and safety of our employees, their families and the public. Health, safety and environment (HSE) performance is a core value and will be managed as an integral part of our business to benefit employees, neighbors and shareholders. All FMC Energy Systems employees are responsible for assuring that we achieve continuous and measurable improvement. With safety as a top-down, bottom-up responsibility – and with results tied to management and employee performance appraisals – our formal HSE safety program identifies and rewards behaviors that improve safety practices. FMC Surface Wellhead conducts ongoing safety training programs with daily, weekly and monthly service safety meetings. We also require formal job-safety analyses (JSAs) for all service jobs. The JSA gives our service technicians a convenient procedure for reviewing the job with the rig crew, heightens the awareness of safety risks, and focuses on using the right tools for the job.

Equipment Costs Do Matter FMC Surface Wellhead understands that the cost of your wellhead system is part of your purchasing criteria. We also understand that the best way to reduce your cost is to use the right equipment for your application. The only thing more expensive than a feature you don’t need is a system that does not meet your requirements. For more than seven decades, our company has demonstrated the ability to supply worldwide to the oil industry with wellhead systems that have matched the applications requirements. We know about wellhead equipment, and we know about delivering it around the world. Those make us feel comfortable offering you to reduce your cost by working together in the specification of your requirements. Thank you for taking time to learn more about our company.

O ff s h o re Designed to Save Time, requires only one major Nipple-Up of the BOP The OBS surface equipment used with SD-1 mudline system has been designed to save time in assembly and disassembly of this unique drilling tool. The major time savings occur when the well is being abandoned. Access to the hanger and packoff/support bushing can be achieved by nippling down the connection at the casing head and lifting the OBS system as a single unit.
Op e r a t i o n s
The OBS surface wellhead has three functions: ➤ To suspend casing risers at the rig ➤ To provide for annulus packoff seals between casing risers ➤ To support the BOP stack When the OBS system is being installed, all of the wellhead spools can be installed as a single unit with the BOP stack on top after installation of the casing head and lowermost packoff/ support bushing. All subsequent casing
CM-1 The CM-1 is a subsea tree utilized to complete subsea wells on mudline suspension systems for shallow waters to 400 feet. ➤ Allows fast-track completions resulting in early production. ➤ Proven, cost effective solution for shallowwater marginal field development. ➤ Allows to tie back to most mudline suspension designs.

hangers and multifunction packoff/support bushings can be installed without nippling down the BOP stack or inserting additional casing spools. In the system shown, additional time savings are achieved through the use of Speedloc II connections on the spools. These connections allow easy and quick access to install hangers and packoff/ support bushings. OBS surface equipment is furnished with clamp connections for 21 1/4˝ 2K, 13 5/8˝ 5K and 13 5/8˝ 10K.

Solutions
Since our days as O-C-T, we’ve led the industry in solutions that save rig time and enhance the safety of your operation. Both those aspects were taken into account when we developed our Diverter Attachment wellhead product offering. One of the inherent dangers of the industry is working under the Diverter/BOP stack when it is being installed or removed. The features we have incorporated in our Diverter Attachment Assemblies greatly minimize the amount of time one is required to spend on the wellhead deck during these operations. Time savings were also a strong consideration taken into account during the development of our Diverter Attachment assemblies. Depending on which design best fits your application, we have incorporated such features as no requirement to wait on cement to set, elimination of “hot work,” ability to land multiple casing strings without nippling down and the speed associated with the installation and removal of the Slip Loc and Speedloc ® quick connections. Depending on which design is selected, the operator could achieve between 6 and 36 hours of rig time-savings.

The wellhead is provided with two load shoulders that allow the operator to land and pack off both conductor and surface casing without ever needing to nipple down. F e a t u re s a n d B e n e f i t s ◆ The wellhead bottom is equipped with a Slip Loc connection and the top with a Speedloc® connection. Both these connections save considerable rig time during installation. ◆ Seals the well bore while drilling out for conductor and surface casing. ◆ If used in conjunction with a mechanical casing cutter, this design eliminates the need for welding; thus there are no longer the dangers associated with “hot work.” Further, adjacent wells do not have to be shut in during installation. ◆ The conductor casing string is landed, packed off and tested prior to cementing. If it is desired that returns be taken across the shale shaker, a flow loop can be installed during the cementing operation. ◆ The surface casing is landed on the upper load shoulder with a fluted hanger for flow by. Once cementing operations are complete, the pack off is run, locked in place and tested prior to nippling down. ◆ The diverter riser assembly is removed and subsequent wellheads installed with the use of the Speedloc® connection, which is designed to save valuable rig time. ◆ Available in Slip Loc or butt-weld prep for 30˝, 26˝ & 24˝ drive pipe.

Clamps
Description: To reduce installation time and wellhead equipment size, FMC Surface Wellhead uses clamp devices in place of flange connections for wellheads. The Speedloc ® Clamp consists of a series of segments which are mechanically isolated from one another, permitting each segment to act as an independent clamp. These clamp segments pull the integral mating hubs together as the nuts are tightened. The contact surface between the segments and the hubs acts as a ramp to maximize vertical clamping force.
FMC Surface Wellhead’s integral Speedloc Clamps can be pre-installed on wellheads, BOPs and other drill-thru components with no rig assembly time required. One person can make up all sizes of Speedloc Clamps in less than 10 minutes. The increased strength and reliability of Speedloc Segmented Clamps over two-piece clamps help ensure safety in the field by greatly reducing the risk of a failure. Other factors inherent in the design of the Speedloc Clamp that help maximize personnel and rig safety include the elimination of special tools, handling devices and loose parts, minimizing time and exposure of service personnel in the area of the wellhead. FMC Surface Wellhead currently offers two versions of the Speedloc design:
Speedloc I: Proven worldwide, Speedloc® Clamps are available in nominal sizes from 7 1/16 to 21 1/4 inches for standard and sour-gas services to 20,000 psi. They provide distinct mechanical and operational advantages over alternative connectors, and are ideal for high-temperature applications. Straight-bore metal seal
Speedloc-I Segmented Clamps use FMC Surface Wellhead’s patented straight-bore metal seal (SBMS) rather than the standard API seal (R, RX or BX) found in other wellhead connectors. The SBMS seal is preloaded radially during assembly as the clamp segments pull the mating hubs together. Therefore, the Speedloc Clamp does not require further vertical preload to generate a seal. Sealing integrity is maintained by radial compression of the seal against the machine surfaces of the seal pocket. Fluctuations in vertical end loads and externally applied bending moments do not affect the function of the seal. Speedloc-I Clamps provide high bending moment and shear-resistance capacities, far exceeding conventional two-piece clamps in strength. Under well pressure conditions, the total load is distributed equally between the Speedloc-I Clamp’s studs, with only moderate torque required for full stud preload. The loss of a single Speedloc-I Clamp stud results in only 8.3% drop in clamp preload, therefore maintaining 91.7% of the installed connector’s preload. In contrast, if one stud fails on a two-piece clamp, failure of the entire clamp could occur.

Speedloc II: Proven worldwide, Speedloc-II Clamps are available in sizes from 7 1/16 to 21 1/4 inches for standard or sour-gas services to 20,000 psi, 0oF to 250oF, providing mechanical and operational advantages over other connectors. Superior “clamping” by design
The Speedloc-II Clamp consists of a series of segments which are mechanically isolated from one another, permitting each segment to act as an independent clamp. The Speedloc II uses a travel nut with a retainer bolt to secure the segments onto the hub. When the travel nuts are being loosened, the retainer bolts keep the nuts and segments together, causing the nuts to positively retract the segments. The Speedloc-II nut threads are coated to provide a lower coefficient of friction, reducing make-up torque and dramatically increasing thread life. The result: you get enhanced clamping and higher end load capacities in a compact, preassembled design with significant safety advantages. Mates with conventional clamp hubs
31
Clamps
FMC Surface Wellhead’s Speedloc-II Clamps mate to conventional clamp hubs using API RX or BX ring gaskets. The design allows for interface between FMC Surface Wellhead and existing conventional clamp hub equipment. The Speedloc II can also be provided with FMC Surface Wellhead’s straight-bore metal seal (SBMS) for special applications. Speedloc-II Clamps maximize strength by distributing total load equally between the clamp’s studs, with only moderate torque required for full preload. Speedloc-II Clamps typically have 12 or 16 studs, depending on the size, versus two or four studs in conventional clamps. As a result, the Speedloc II’s studs are smaller in diameter for the same load-bearing capacity, and require significantly less torque for installation.

TC-60-ET
TC-WD-ET
TC-ET The TC-ET tubing head has one aligning pin and accepts all TC-Series tubing hangers and packoffs except the TC-60 dual-split hanger. It can be upgraded to a TC-60-ET by adding two aligning pins at an FMC Energy Systems facility.
The TC-60-ET is the most versatile tubing head in the oilfield. It has three aligning pins and is compatible with all TC-Series tubing hangers and packoffs, including the TC-60 dual-split hanger. When last-minute completion changes are possible, the T-60-ET is a good investment because no shop modification is needed to adapt it to any type of tubing completion.
TC-WD-ET The TC-WD-ET tubing head has an internal wedge that is used for alignment on specific TC-Series tubing hangers. This particular design allows for alignment of multiple-string tubing hangers without external manipulation methods. TC-WD-ET tubing hangers are generally considered specific to particular customers’ requirements and can be run only in the TC-WD-ET tubing head. FMC hangers that normally are aligned with pins (TC or TC-60 type) will not function in the TC-WD-ET head.
A l t e r n a t i ve Tu b i n g H e a d C o n f i g u r a t i o n s Bottom Connections Bolt-through flange, studded flange and clamp-hub connections are available. The type and pressure rating used must match the top flange of the previous casing spool or crossover flange. Bolt-through flange connections are the most popular and economical type of connection in certain parts of the world. Clamp-hub connections are sometimes specified, because they are much faster to make up and because they reduce the diameter and weight of the assembly when space limitations are present.
Top Connections FMC Surface Wellhead tubing heads have either bolt-through flange or clamp-hub top connections, which are compatible with all FMC tubing head adapters. The producing pressure of the well normally determines the pressure rating of the top connection.
Lockdown Screws Most FMC Surface Wellhead Series tubing heads have a series of lockdown screws in the top flange (unless customer or application requires otherwise). These lockdown screws have three functions: ◆ to actuate compression-type hanger or packoff seals ◆ to lock down the hanger or packoff to prevent movement caused by thermal expansion of the tubing string during production ◆ to lock down the hanger in the event of annulus pressure NOTES: ◆
Where customer preferences or applications do not allow the use of lockdown screws, internally locking mechanisms are utilized. See section on Completion Solutions.

A l t e r n a t i ve Tu b i n g H e a d C o n f i g u r a t i o n s Bottom-Bowl Packoffs (secondary seals) Tubing head bottom-bowl packoffs are used to seal around the production casing stub in the bottom bowl of the tubing head. They are often referred to as “secondary seals.” The various packoff types are described below:
Double FS Seals This design consists of two elastomeric-shaped seals located in grooves in the bottom of the tubing head. A seal is achieved by interference of the seal with the outside diameter of the casing and the bottom or OD of its retaining groove. A spring molded in each inside corner of the seal provides an anti-extrusion mechanism when sealing against pressure by bridging the gap between the tubing outside diameter and casing head seal bore. The shape of the seal allows it flexibility to maintain sealing interference with the large variations in tubing outside diameter.
PI Seals These seals consist of a T-cap seal element, nonextrusion rings and a receiver ring. These components will fit the HPE bottom prep configuration. The PI seal is designed for use up to 15,000 psi working pressure and temperatures up to 75 o F or as low as -50 o F, depending on the elastomer selected. It provides the proper compression and squeeze even with the larger API casing tolerances. The design effectively intensifies the annulus pressure and thus the internal stress in the elastomer to minimize the effects of explosive decompression.
SBMS-II Seals This metal-to-metal seal consists of a “U”-shaped ring with a “bump” sealing surface at the outside and inside legs of the “U.” When installed, the entry ramp compresses the legs of the “U” inward and creates contact stress in each “bump” that provides the seal. This seal requires the casing stub OD to be field machined after the casing is hung to provide the proper sealing tolerances and surface finish. This is accomplished with a portable pneumatic-driven tool. It is good for temperatures ranging from -75 o F to 1200 o F.
RCMS Seals The Rough Casing Metal Seal (RCMS) is designed to use up to 20,000 psi. This seal does not require special machining of the casing stub; is compatible with temperatures from -20 o F to 350 o F in corrosive environments; does not require special installation tools and is simple to install; is NACE compatible; is compatible with casing spool and tubing spool strength; is compatible with casing string strength properties. NOTES: ◆ TC-Series packoffs are usually installed in the tubing head prior to shipment. FMC tubing heads are also available with threaded bottom preparations in some sizes and pressure ratings.

Tu b i n g H e a d A d a p t e r s Description: The tubing head adapter provides a transition between the Christmas tree and the tubing head. The bottom adapter connection matches the tubing head, and the top adapter connection matches the tree. Tubing head adapters are available for all types of single- and multiple-string completions, including those using electric submersible pumps, packers, downhole control valves and gas lift valves. These adapters come with threaded, flanged or studded-flanged top connections. Most tubing head adapters are available with hydraulic supply inlets for downhole control lines. If the customer requires, FMC Surface Wellhead also supplies various types of adapters that will accommodate continuous control-line capabilities. Following you will find the most generally used.
Basic Adapters A4
Dual-Seal Bore Adapters A-4-D
Single-Seal Bore Adapter A4
ESP Adapter
Basic Adapters They provide only a transition between the tubing head and the tree. These adapters do not hang the tubing or provide a controlled seal bore. Basic tubing head adapters have a smooth seal bore and are used when tubing is suspended from the tubing hanger. They are designed for low-pressure completions where downhole line or tubing strings manipulation are not required. The basic adapter is normally installed with the tree after tubing is run.
Features and Benefits ◆ Simple transition piece between the tubing head and the tree ◆ Used with a TC-1A tubing hanger ◆ Available with threaded, flanged or studded top connection
Seal Bore Adapters Seal bore adapters have the inside diameter machined to provide a controlled seal bore for an extended-neck tubing hanger or a seal nipple. They are available with a test port and/or a hydraulic supply inlet for downhole control lines. Like basic adapters, they are normally installed with the tree.
Features and Benefits ◆ Provides a seal bore for the TC-1A-ENS extended neck (Single-Seal Bore) ◆ Provides seal bores for the seal nipples on dual-completion tubing hangers (Dual-Seal Bore) ◆ Available with SCSSV control line inlets ◆ Studded top connection only
ESP Adapters ESP adapters have seal bores to accommodate both a tubing hanger neck seal and an electrical power feed-thru device. Standard ESP adapters are equipped with rotating flanges to mate to the tubing head, minimizing concerns over alignment issues. Positive alignment can be obtained through the use of optional features in the mating ESP hanger. ESP adapters can be supplied to match standard tubing heads rated to 3,000 and 5,000 psi working pressure.

Features and Benefits ◆ Provides sealing bore for a variety of electrical feed-thru configurations, including penetrators, cable packoffs and continuous feed-thru penetrator mandrels. ◆ Provides reliable seal bores for tubing hanger neck or seal sleeves. ◆ Provides rotating attachment flange for ease of alignment to ESP hanger and tubing head flange.
Tubing Suspension Adapter B-2-S
Tubing Coupling Adapter BO-2
Tubing Coupling Adapter BO-10
Tubing Suspension Adapters These adapters provide a means to hang the tubing via tubing threads machined in the lower-connection inside diameter. The tubing threads can be used to suspend tubing when an operator wants to reciprocate tubing, but does not require a back-pressure valve in the tubing hanger. These adapters do not provide a seal. They are normally used on low-pressure completions with a wraparound packoff or stripper.
Coupling Adapters Coupling adapters provide a means to suspend the tubing in conjunction with a special coupling. They provide a lower connection for the tubing head and an upper connection for the tree and are used with a tubing coupling, which suspends the tubing and accepts a back-pressure valve. It is used for high-pressure completions where the operator wants to manipulate tubing through a wraparound packoff or stripper and needs a back-pressure valve and/or a hydraulic supply inlet for downhole control lines. An ACME thread is machined into the adapter’s bottom inside diameter to be utilized in conjunction with the coupling to hang the tubing. Then it can be screwed onto the coupling. When a tree is trimmed for critical service, a coupling adapter with a coupling nut is available to prevent possible galling of threads between the adapter and coupling on makeup.
BO-2 Coupling
BO-10 Coupling
Features and Benefits ◆ Used with the BO-2 tubing coupling ◆ Adapter makes up to the tree. ◆ Entire assembly is installed by rotating it onto the coupling. ◆ Studded top connection only

Description: Tubing hangers are installed in the top bowl of a tubing head. Tubing hangers both suspend tubing and provide a primary annulus seal between the tubing and production casing. Hangers are run through the blowout preventers and are landed in the top bowl of the tubing head. Tubing hangers are available for any type of tubing completion. Tubing hangers also act as a means to access and manipulate additional smaller tubing lines that are utilized downhole and extended to the surface on the outside of the tubing string or strings. Packoffs allow tubing string manipulation for setting packers or displacing fluid while sealing the annulus between the tubing and the production casing.
FMC Surface Wellhead TC-Series tubing hangers are available for any type of single- or multiplestring tubing completion, including those requiring packers, subsurface safety valves, gas-lift valves and electric submersible pumps. All FMC Surface Wellhead hangers can be run through the blowout preventers, allowing the well to be secured before the preventers are removed. Most TC-Series tubing hangers accept a back-pressure valve, which seals the tubing bore. These BPV profiles may be of FMC Surface Wellhead design or they may be of another manufacturer’s design, depending upon the customer’s requirements. Some hangers are ported for hydraulic control lines, downhole safety valves or other equipment as required by the customer.
S i n g l e - S t r i n g Tu b i n g H a n g e r s Most TC-Series single-string hangers do not require aligning pins and are compatible with any TCSeries tubing head. Generally speaking, alignment pins will not be required unless there is a need to orient a hanger a particular way. An example of this might be when an additional line is being run with the tubing string and needs to be ported through a particular position in the tubing spool.
TC-1A
TC-1W
TC-1A The TC-1A is a threaded tubing hanger with an integral compression-type annulus seal that is actuated by string weight and or by lockdown screws. This hanger is also known as a threaded mandrel-type hanger and is considered one of the most basic and least expensive hangers in FMC Surface Wellhead’s TC product line.
TC-1W The TC-1W is a split, wraparound packoff that allows tubing-string manipulation to displace fluid while maintaining complete control of annular pressure. Like all TC-Series packoffs, tubing string weight must be suspended from a tubing suspension adapter or coupling adapter. The TC-1W has a compression-type seal which is actuated by lockdown screws.

BO-2 Coupling
Page 13
BO-10 Coupling
TC-B-EC
BO-2 Coupling A BO-2 coupling-type tubing hanger uses a one-piece coupling that is externally threaded with a coarse heavy-duty ACME thread. Internally the coupling will provide tubing threads in the top and bottom along with a back-pressure valve groove. The BO-2 coupling is attached to the last tubing joint and is run in conjunction with a TC-1W wraparound-type packoff. Ultimately, the BO-2 coupling is made up into a BO-2 adapter that is assembled on the bottom of the Christmas tree.
Features and Benefits ◆ Threaded coupling is used in conjunction with the BO-2 tubing head adapter for high-pressure completions requiring both string manipulation with BOP protection and SCSSV control lines. ◆ Requires a TC-1W wraparound annulus seal. ◆ FMC Surface Wellhead “ISA” back-pressure valve preparation is standard.
BO-10 Coupling The BO-10 coupling-type tubing hanger is generally utilized on completions demanding higher completion shut-in pressures. This hanger is a coupling by design but also incorporates a separate rotating, ACME-threaded locking nut. This design is also attached to the last tubing joint, and is run in conjunction with a TC-1W wraparound-type packoff. Ultimately, the BO-10 coupling is made up into a BO-10 adapter that is assembled on the bottom of the Christmas tree.
Features and Benefits ◆ Coupling nut allows the BO-10 coupling to be installed without rotation of the tree, making it the choice for heavy trees or where dissimilar metals could cause galling problems. ◆ Requires a TC-1W for annulus seal.
TC ESP The TC ESP hanger is dual-ported, with one port designed to accept a single production tubing string. The second port is designed to accommodate the electrical conductors that pass the current between the surface cable and the subsurface cable that goes to the pump. The TC ESP hanger is designed for 7 1/16"- 3,000/5,000 and 11"- 3,000/5,000 flange sizes. We standardized on EUE thread configurations. Nevertheless, additional thread profiles and different configurations can be supplied. While configurations and designs may differ with customer requirements, the basic design concepts stay the same.
Features and Benefits ◆ Has redundant “B” Type “S” seals on the body of the hanger. ◆ No alignment groove. It has an attachable alignment plate on the bottom of the hanger when alignment is required. ◆ No threads for penetrator makeup. Penetrator will be equipped with a “jam” nut on the bottom of the penetrator to hold in the hanger body.
Benefits ◆ Can easily convert an existing flowing well to an ESP without the need to change out the tubing head. Can utilize a TCM-type tubing head. ◆ Can convert a finished hanger with a QCI penetrator profile to accept a BIW penetrator.

Penetrator does not require rotation for makeup. Eliminates the potential of seal or thread damage when rotation of penetrator is necessary.
Multiple-String Tubing Hangers and Packoffs TC-Series multiple-string hangers and packoffs permit the independent suspension and sealing of multiple-tubing strings, allowing simultaneous production or injection to or from separate zones. They require one or two aligning pins in the tubing head bowl and are compatible with either TC or TC-60 tubing heads. The TC-60 split-type hanger may be run only in the TC-60 tubing head.
TC-60 Dual-Split Hanger
TC-2C
TC-60 Dual-Split Hanger The TC dual-split hanger is an easy-to-run split hanger with an integral compression-type packoff. The packoff seal is actuated by lockdown screws before the blowout preventers are removed. No plastic injection is required. With the TC-60 dual-split hanger, tubing strings can be run and pulled independently, allowing maximum clearance for gas-lift or subsurface safety valves. Each segment accepts a back-pressure valve and is available with control-line preparations for surface-controlled subsurface safety valves.
Features ◆ Allows tubing string to be run and pulled independently. ◆ Provides for maximum clearance for gas-lift valves, SCSSV and packers. ◆ FMC Surface Wellhead “ISA” back-pressure-valve preparation in each hanger half is standard. ◆ Tubing head must have the dual TC-60 aligning pins.
TC-2C Dual Completion ◆
Has threaded, coupling-type multi string hanger. Allows tubing strings to be run separately or simultaneously; tubing can be rotated to manipulate packers. ◆ Each accepts a back-pressure valve. ◆ Annulus and sleeve seals are interference-type. ◆ Tubing head must have the single aligning pin. ◆
Hydraulic Control-Line Preparation The TC-1A-EN tubing hanger and the TC-60 dual-split-type tubing hangers are available with hydraulic control line ports for surface-controlled subsurface safety valves or injection tubing. The TC-1W packoff and the BO2 adapter/coupling with concentric tubing joint can also accommodate a subsurface safety valve.Control-line ports may be either threaded with seal sleeves or continuous, depending upon customer requirements.

Time Optimization (DTO) System
Rocky Mountains (United States) Our customer’s infield drilling program needed to minimize his rig time for multiple shallow wells (with surface casing pressures less than 5,000 psi) and to improve safety. FMC Surface Wellhead’s solution was the DTO ® wellhead, which delivers significant time savings by eliminating a number of steps in the traditional drilling process and reducing time required for other steps. The ideal situation for using the DTO would be a single rig that’s drilling multiple consecutive wells by using a common casing program. Each rig is outfitted with a DTO diverter connector fabricated into a diverter riser. The assembly stays with the rig for the drilling project, and it is used on each well. A DTO drilling spool connector is assembled into the rig BOP and is moved with the rig from well to well. Features and Benefits ◆ Eliminates steps in the drilling process. ◆ Offers time savings during nipple up/down of the BOP’s stack, landing casing hanger and installing the tubing head. ◆ Increases safety by eliminating the need for cutting torches and hammer wrenches. ◆ Locking ring design on drilling spool provides 360 degrees engagement to increase load capacity and reduce fatigue. ◆ Contingency systems for stuck pipe retains system benefits and time savings. ◆ Tests production casing seals prior to removal of BOP. ◆ Load capacity of surface casing hanger exceeds joint strength.

China Sea (China) This project in the China Sea’s Ya Cheng field, which supplies gas energy to Hong Kong, presented the challenges of critical conditions: high corrosive, high temperature, fire resistant, severe weather, large-bore production, high reliability and a long life cycle to reduce the need for workovers. Our state-ofthe-art “dry tree” system, the UWD-15, is an excellent example of our quest to design highly reliable wellheads for difficult environments and conditions and still contain costs. Developed out of our subsea wellhead technology, the UWD-15 is a 15,000 psi wellhead that combines advanced technology for high-pressure and hazardous-service environments. All seals are metal-tometal, with the UWD-15 packoff providing the basis for annular sealing. This packoff does not rely on the tubing hanger weight to energize and can be removed separately from the tubing hanger. It utilizes an SBMS seal at the tubing hanger neck as standard. The seat is recessed to help ensure that the seal contact surface is not damaged when the packoff is installed. The design includes a fire-safe envelope for the upper master valve to the annulus A. Features and Benefits ◆ The 15,000 psi wp UWD-15 Wellhead System minimizes leak path to the environment. ◆ Has a metal-to-metal seal, SBMS technology. ◆ Includes internal latch. ◆ Has major connections with Speedloc ®. ◆ Offers field-proven advanced technology. ◆ Standard subsea tooling facilitates availability and learning processes.

Gulf of Campeche (Mexico) Injecting 1.2 million cubic feet of nitrogen per day into a formation through a 9˝ bore is a major challenge to face with traditional solutions. The limited available height and weight on the platform plus the handling of a 9˝ Christmas tree during installation and workover ruled out a conventional production wellhead solution. Our engineers who have platform working experience understood better than other suppliers the operational challenge, and proposed the first horizontal wellhead tree system of its size in the Gulf of Mexico. Features and Benefits ◆ Full 9˝ bore system. ◆ Allows workover without removing Christmas tree. ◆ It has hydraulic or pneumatic valves. ◆ Wire Mesh FMC Surface Wellhead seal technology. ◆ Allows drilling through the tubing hanger. ◆ Maximizes platform’s available surface.
Side-By-Side
(SXS)® System
Java Sea (Indonesia) Fragmented reservoirs requiring multiple interventions are a major challenge due to the reduced space on platforms, especially when, as in this example, you need to complete (or abandon) wells and perform interventions without disturbing adjacent wells. For such challenges, FMC Surface Wellhead has developed a Side-By-Side (SXS) Wellhead System for optimization of space on new platforms or workovers on existing platforms. The SXS also accommodates configurations involving a combination of single and dual completions inside a single conductor. Features and Benefits ◆ Allows installing either a 2-in-1 or 3-in-1 well configuration inside a single conductor, sized from 26˝ OD onwards to suit requirements. ◆ Eliminates the need for additional conductor pipe. This creates up-front savings and reduces abandonment costs. ◆ Allows the use of standard drill-bit sizes. ◆ Independent Tubing Heads (Unihead ®) allow greatest flexibility in choosing wells to complete or abandon and to perform independent intervention, entry and re-entry without disturbing adjacent wells or flow lines. The wellheads are installed with full BOP protection. This system promotes time saving through batch drilling and drilling with reduced rig move time. ◆ Maximize platform size and the use of well slots on the platform. For existing wells, the SXS wellhead maximizes the use of existing spare well slots.

Gulf of Mexico (USA) By far the most experienced suppliers of TLP/SPAR systems in the Gulf of Mexico, we also installed the deepest and most fire-resistant SPAR in the Gulf. As certain platforms are designed to move with water action, every element connected to the sea floor becomes an integral part of a dynamic system and requires specialized wellhead solutions like our TLP/SPAR systems. From the initial stages of your project, we can help you decide to go with a “wet” or a “dry” tree. Example: If you’re facing a fragmented reservoir offshore and must execute multiple interventions, economics indicate a surface tree. FMC Surface Wellhead installed the first TLP/SPAR system in the Gulf of Mexico during the 1980s and has been the leader in this technology since, installing more systems worldwide than our competitors combined. Features and Benefits Special slip-lock assembly securely attaches wellhead to riser. ◆ Straight-bore metal seal (SBMS) provides a more secure seal against heavy sideloads that can be generated by wave activity. ◆ More compact profile reduces vertical space requirement. ◆ New tubing head design provides full metal-to-metal seal. ◆ Special plug and lubricator adapter provides easy vertical access to the gas-lift string. ◆ SCSSV and inhibitor lines exit through the upper wellhead connection. ◆

A wellhead is as good as its valves, and FMC Surface Wellhead’s valves are as good as it gets.
S e r i e s 1 0 0 G a t e Va l v e s FMC Surface Wellhead’s Series 100 Gate Valves have successfully met customer demands for performance, endurance and ease of maintenance since their introduction in 1984. Available in working pressures from 2,000 to 20,000 psi, these metal-seal gate valves provide bubble-tight operation throughout their rated pressure and temperature ranges. Sizes, configurations and materials are available for virtually any application. Model 100 Series Valves by far exceed the requirements of API 6A. Model 120, Model 125, Model 130, Model 135, Model 160 and Model VLT have been qualified in excess of Appendix F for material class AA to HH and temperature rating –75 to 400oF. An additional 300 endurance cycles are applied to simulate 20 years of life expectancy. Series 100 gate valves come in trims for a complete range of water, oil and gas services – including corrosive, high-temperature, subsea, arctic, sand and steam.
Belleville spring
Metal-to-Metal seal design FMC Surface Wellhead’s Series 100 gate valves use a precision-machined floating slab gate and seat design that provides a fully energized metal-to-metal seal between the gate and seat surfaces at all times. A Belleville spring behind each seat keeps the seat in contact with the gate to ensure effective sealing at very low pressures. These fully symmetrical valves effectively seal against flow in either direction. Even though the seats “float” in their respective pockets, the downstream seat still creates a metal-to-metal seal against the body when the valve is closed. The back face of each seat has FMC Surface Wellhead’s exclusive double-bump profile (right figure). As the valve closes, line pressure forces the gate against the downstream seat, which in turn is driven against the back of the pocket, where the double bumps form a gas-tight, metal-to-metal seal.

Balanced stem with metal back seat and patented UV stem packing
L O N G L I F E E X P E C TA N C Y A N D R E L I A B L E O P E R AT I O N Key features to ensure reliability for the life of the valve are: Metal-to-metal sealed bonnet assembly: Separate weather seals on the Series 100 valve bonnet assemblies isolate the stem, stem bearings, packing nut and other internal components from external environment. Heavy-duty stem bearings: Dual stem bearings support all axial loading on the stem. These low-friction, tapered roller bearings also help reduce operating torque. High-strength stem threads: Standard ACME threads offer high shear strength and high contact area for maximum endurance. A separate gate-lift nut contains the mating threads instead of the gate itself. This flexible design permits optimum stem/lift nut material combinations and allows the gate to float independently from the stem. In the unlikely event of thread damage, only the nut or stem needs to be replaced. Stem shear pin: The stem is protected against accidental twist-off by the stem shear-pin. The pin can be quickly replaced without disassembling the valve bonnet. Close-fitting gate guides: Stainless-steel gate guides stay within a few thousands of an inch of the gate, acting as mud skirts to minimize well fluids, sand and mud from entering the valve body as the gate opens and closes.

A ctuators
FMC Surface Wellhead offers its own actuator product line that includes the HP–PN Pneumatic Piston, the HP–HYW Hydraulic Wire Shear Actuator and the HP–HY Hydraulic Piston Actuator. This design has been proven worldwide in the field for more than 35 years.
D e s i g n F e a t u re s o f t h e F M C S u r f a c e We l l h e a d P n e u m a t i c a n d Hydraulic Actuators: ◆ ◆ ◆ ◆ ◆
The actuator is fail-safe/fail-close because it will close with the loss of control pressure, with or without pressure in the valve body. Heavy-duty coated spring package is designed to provide closing force at zero or low pressure. Actuators are designed with back-seat capability. Designed to accept our full range of accessories, i.e., stem protectors, fusible lockout caps, etc. Quick-disconnect design and spring box design reduces time required during maintenance operations.
HP– PN Pneumatic Piston Actuator mounted on a reverse-acting gate valve. The HP-PN Pneumatic Actuator is designed to be failsafe and fail-close. When installed as part of a safety system, it will automatically close with the loss of control pressure and will open automatically when the control pressure is restored.

Description: The Type HP-PN Pneumatic Piston Actuator is a ratio-piston-type actuator
26FMC7(pg62-85)_4.6.04

Functions ◆ ◆ ◆ ◆
◆ ◆
Actuators are used on secondary master valve and/or wing valve of a Christmas tree, flow lines, header valves, gathering lines and pipelines. As part of a surface safety system, the actuator will shut off flow from the well in the event of a catastrophic event. The HP-PN surface safety valve is a pneumatic-controlled actuator that is operated by an air or gas source. Pneumatic pressure acting on the piston holds the valve open. Loss of pneumatic pressure in the actuator’s cylinder allows the well or flowline pressure acting on the area of the lower stem to force the stem and gate closed. Pneumatic actuators can be used in both gas and oil wells. Care should be taken when using pneumatic actuators on high-pressure and/or large-bore applications. One of the opening characteristics of a pneumatic actuator is that once sufficient force is generated to break the differential, the valve will instantaneously go from closed to full open. This causes a slam-open effect that can cause damage to gates and seats. This can potentially damage the actuator. The following are some methods to reduce this potential problem: o Reduce the differential pressure across the valve. o Reduce the volume of air in the cylinder. o Dampener mechanism. o Use of a hydraulic actuator is considered the best option.
Benefits ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆
Loss of control pressure above the piston will cause the actuator to close the valve. In the event of a fire, the metal-to-metal seal between bonnet and lower stem acts as a secondary seal if the stem packing is damaged. Has a back-seat test port and packing leak detection port. A relief valve on the cylinder prevents overpressurization. Large piston area permits use of low-pressure air or gas control systems. Has a rising stem for visual indication. Pneumatic cylinder and piston are electrolysis nickel plated for corrosion resistance, reducing repair cost. Upper stem packing is easily removed. P N E U M A T I C

HP– HY Hydraulic Piston Actuator reverse-acting gate valve. The HP-HY Hydraulic Actuator is designed to be fail-safe and failclose. When installed as part of a safety system, it will automatically close with the loss of control pressure and will open automatically when the control pressure is restored.
Functions ◆ ◆ ◆ ◆
◆
The actuators are used on secondary master valve and/or wing valve of Christmas tree, flow lines, header valves, gathering lines and pipelines. As part of a surface safety system, the actuator will shut off flow from the well in the event of a catastrophic event. The HP-HY surface safety valve is a hydraulically controlled actuator that is operated by a closed hydraulic system completely independent of well fluids and pressure. Hydraulic pressure acting on the piston holds the valve open. Loss of hydraulic pressure in the actuator cylinder allows the well or flowline pressure acting on the area of the lower stems to force the stem and gate closed. Recommended for use in high-pressure and/or large-bore applications.

Seal echnology Seals are critical for achieving reliable pressure integrity in wellhead equipment. FMC Energy Systems is proud of our sealing designs, and we would like to share our seal technology with you so you can take it into account next time you specify your equipment. Common oilfield elastomers are sufficiently reliable for low-pressure, normal-service oil and gas wells, and special elastomer compounds and designs are available for critical-service wells. However, all elastomer compounds lose some of their sealing effectiveness over time, with the rate of degradation dependent on environment. Sometimes a metal seal option can be a cost-effective way to increase service life and improve production efficiencies. FMC Energy Systems has the expertise to help you decide the best fit (elastomer or metal) for your application.

A number of the more conventional wellhead seals can no longer meet the new stringent design-acceptance criteria, such as the larger API casing and tubing OD tolerances now allowed by API Spec-5CT. For example, the conventional O-ring seal is very limited in its ability to bridge large extrusion gaps and remain intact without some kind of antiextrusion device. In addition, some seal designs cannot keep a bubble-tight seal over the wide temperature ranges and large pressure variations encountered. FMC Energy Systems’ response to these new API requirements addresses the limitations found in traditional interference and slab-packing applications with the following key design features: ◆ Seals meet API Spec. 6A, Appendix F, Performance Requirement Level Two (PR-2) pressure and temperature cycle testing. ◆ All seal designs utilize one of the FMC proprietary elastomeric compounds. These seal compounds are rated for all API material classes, including class HH (H2S/CO2 service), and are also amine resistant. ◆ Antiextrusion devices are incorporated into each type of seal design to compensate for thermal expansion/contraction of the seal element and for installation clearances. ◆ All seal elements and antiextrusion components are continuous. ◆ Antiextrusion devices are integrally molded into the seal element, making them easier to install and more durable. ◆ All seals are designed to provide proper squeeze, volume fill and stretch under all API/FMC tolerance conditions, i.e., the largest diametric gap possible and the worst-case misalignment of sealing surfaces.

FMC Energy Systems’ patented “bump” seal design has addressed many issues traditionally associated with metal seals to become a technological breakthrough for wellhead equipment. FMC Energy Systems’ metal seals are rugged enough for the oilfield operation, have simple installation procedures, are easily tested after installation and are reusable in most applications. In most applications FMC Energy Systems metal seals are “self energizing” and do not rely on a wedging action, suspended weight or flange make-up force to affect a seal. The seal is “pressure assisted” and can work in any pressure. ◆ Meet API Spec. 6A, Appendix F, Performance Requirement Level Two (PR-2) pressure and temperature cycle testing. ◆ Are rated for all API material classes, including class HH (H2S/CO2 service) and are also amine resistant. ◆ Can be made from almost any high-strength steel or corrosion-resistant alloy, for use in extreme corrosive services. ◆ Work in all temperature ranges, from -75°F arctic service to 1200°F for fire-resistant applications. ◆ Are easy to install and test and can withstand standard oilfield handling. ◆ Do not deform (crush) metal, either on the seal or on the mating surfaces, so both are normally reusable, minimizing workover costs.

E lastomer Seals S-Seal The S-Seal is designed to provide reliable sealing between machined components. It is a versatile and reliable seal in cyclic high-pressure and -temperature applications, where conventional interference-type seals (O-rings, belt packing, dovetail, etc.) are typically inadequate. The S-Seal is an interference-type seal utilizing metal coil springs molded integrally into the exposed seal corners as antiextrusion devices. Another important feature of the FMC design is the use of a “continuous” coil spring, which eliminates weak points around the seal’s circumference. The S-Seal can be used in many applications where there is a controlled/machined gap between the sealing bore and shaft; for example, a mandrel hanger neck and tubing head adapter bore. There are both O.D. and I.D. applications of the S-Seal, with sizes available in nominal diameters up to 20˝. The S-Seal design can be rated up to 10,000 psi working pressure and a 0° to 250°F temperature range for all sizes. Special designs allow qualification to 15,000 psi working pressure and 300°F.
S-Seal
FS-Seal The FS-Seal has been designed to seal against rough casing where wide tolerances and varying surface finishes create difficult sealing conditions. It is utilized as a large cross-section interference seal to bridge large extrusion gaps associated with sealing on rough mill casing. The bump provides higher sealing contact stresses, while the curved recess on the back of the seal controls the amount of compression (squeeze) on the seal element by allowing it to deflect outward when sealing against a larger-than-normal outer-casing diameter or an out-of-round section of casing. The FS-Seal can be supplied integral to a casing-head bottom preparation as a 1-FS (one seal with no secondary) or 2-FS (two seals with one secondary) packoff. It can also be supplied as a separate 4-S packoff bushing, which incorporates a secondary S-Seal on the bushing OD and a secondary FS-Seal on the ID. The FS-Seal is available for 4 1/2˝ to 30˝ pipe sizes. The FS-Seal is rated to 10,000 psi working pressure and a 0° to 250°F temperature range for sizes up to 16˝, while the larger sizes are rated to 5,000 psi working pressure.

Compression Packing with Wire Mesh This design is mechanically energized by lockdown screws after assembly and utilizes integrally molded wire mesh rings on top and bottom of the elastomeric element to increase extrusion resistance. Its design and elastomer compound enable excellent temperature and environmental resistance. It can be used up to 15,000 psi working pressure and a -50° to 250°F temperature range. The wire mesh is annealed 316 stainless-steel material for corrosion resistance.

PI Seal The FMC PI Seal design is an extremely reliable high-pressure sealing mechanism. The PI assembly is comprised of an upper junk ring guide, the pressure-intensified (PI) seal assembly, and lower ACME threaded lock ring to hold the packoff in the bottom of the tubing head. The PI design addresses some rather complex problems associated with oilfield elastomer seal designs, including explosive decompression, extrusion at high pressures/temperatures, and seal shrinkage/poor response at low temperatures. The PI seal uses the casing annulus pressure to generate a higher pressure in the elastomer seal, which eliminates the diffusion of gas into the elastomer. This pressure intensification is generated by a movable “T” ring which creates an unbalanced pressure area across the elastomer seal. This design is coupled with FMC’s proprietary seal formulation, which also has improved gas permeation as well as excellent oilfield fluid resistance. The T-ring design also allows the elastomer to self-compensate for seal stress fluctuations caused by thermal cycling. The movement of the T-ring automatically controls excessive seal stresses caused by elastomer expansion. At very low temperatures, the phenomenon of seal stress relaxation caused by elastomer shrinkage is again automatically compensated for by annulus pressure applied to the unbalanced area T-ring. Seal failure due to extrusion is addressed by the use of automatic “ramping” antiextrusion rings made from thermoplastic material. The antiextrusion rings are located at all four corners of the seal. These rings compensate for the extrusion gaps caused by API casing tolerances and manufacturing head tolerances. The PI seal is rated to 15,000 psi working pressure and was developed for use as a lower casing or tubing spool packoff where long-term reliable sealing in hostile environments is required.

M etal Seals SBMS Seals FMC Energy Systems’ straight-bore metal seal (SBMS) is energized by interference between the designated primary sealing surface and the metal seal’s contact area with that sealing surface. The SBMS is a nonintegral double-ended seal sleeve manufactured from high-strength, low-alloy steel or corrosion-resistant alloy. The seal can be installed separately and can be easily replaced. The seal design is based on an interference fit with pressure-intensified sealing. As the tubing head bonnet is nippled up, the seal lip (“bump”) engages an entry ramp in the seal bore, radially deflecting the seal lip inward, creating the contact stress required to effect a seal. In the fully installed position, the seal lips engage a straight bore above the entry ramp (see illustration). The SBMS maintains sufficient contact-sealing stress even at very low pressure. As working pressure increases, contact-sealing stresses increase, making it seal even tighter. The SBMS qualification tests were conducted with low pressure and high pressure, the fire test pass (API RP-6F “Improved”) of 2,000°F flame temperatures and 1,200°F internal seal temperature with zero leakage.
SBMS-II Seals The SBMS-II has “bumps” on the inside diameter and the outside diameter. Each seal lip engages its entry ramp, creating the sealing contact stress with the sealing diameter. The SBMS-II is used mainly as a production casing metal seal on either extended-neck mandrel-casing hangers or directly against the casing stub when slip hangers are used. When employed to seal against a casing stub, it is required to machine the casing stub after the casing is hung off. However, it requires only approximately 1 1/4˝ of the casing stub. The operation can be executed with a portable pneumatic tool. The SBMS-II is normally used on production casing where extreme temperature fluctuations are anticipated or in critical-service applications. When used against slip-suspended casing, FMC Energy Systems provides an ACME threaded casing holddown nut to minimize upward thermal expansion of the casing and act as a bit guide to protect the SBMS-II seal when running tubing or conditioning the hole. The SBMS-II seal has been used in sizes up to 20˝. Various applications of the SBMS-II design include valve stem back-seat seals, valve seat body seals and tubing hanger annular packoffs.
RCMS Seals The most recent addition to the family of metal seals is the rough-casing metal seal (RCMS). This seal design does not require special complex field machining of the casing stub; is compatible with a wide range of temperatures and corrosive environments; does not require special installation tools and is simple to install; is NACE compatible; is compatible with casing spool and tubing spool strength; and is compatible with casing string strength properties.
XEMS Seals FMC Energy Systems’ externally energized metal seal (XEMS) is used in Unihead ® wellhead systems for special mandrel casing hanger and tubing hanger applications. The externally energized seal requires mechanical force to effect a seal. The XEMS seal can be run through the BOP stack and is energized by lockdown screws or by an internal lockdown ring and running tool.

Metal-to-Metal High-Performance Seals The metal-to-metal high-performance (M2M HP) Annulus Seal Assembly seals the annular space between the Unihead and the UWD-15 Casing Hangers. The seal is preloaded at installation, giving outstanding sealing performance even at low pressures. Two seal bumps on the OD of the M2M HP seal assembly seal against a recessed groove in the ID of the Unihead. Three radiused seal bumps on the tapered ID of the M2M HP seal assembly seal against the mating tapered surface on the OD of the casing Hhanger. The seal element material is a corrosion-resistant alloy, rendering the seal assembly fit for use in carbon dioxide environments. All mating equipment is overlaid with a corrosion-resistant alloy. The seal bumps plastically deform during installation, filling scratches that may be present on the sealing surfaces. The M2M HP seal assembly OD locates and aligns within the bore of the Unihead during installation and centralizes the M2M HP seal assembly. The OD also protects the two seal bumps on the seal assembly OD from damage during installation. A square shoulder in the bore of the locking mandrel sits on top of the casing hanger. The M2M HP seal assembly is positioned in the Unihead so that the seal elements align with an undercut in the Unihead bore. This undercut area minimizes scratching or scuffing of the seal surfaces which can occur during drilling operations. When the energizing mandrel is operated, locking segments engage with a groove on the ID of the Unihead. A lock ring in the ID of the M2M seal assembly engages with a groove on the OD of the UW-D15 Casing Hangers. The M2M HP seal assembly bottom surface protects the seal by having a larger diameter that shields the retracted sealing elements during running. The M2M HP seal element is retained on the seal assembly with a retainer strip. This retainer strip is held captive and provides uniform support during seal retrieval. The M2M HP Annulus Seal Assembly is designed to prevent premature energization as the assembly is run downhole. It is rated for 15,000 psi, H2S service and 250oF service. They were successfully tested to 350oF.

Ca p a b i l i t y
wellhead is as good as its valves and seals, and
performance is about seal performance. Higher pressures, well-treatment chemicals, longer frac times and other critical-service conditions place emphasis on seal integrity. If a seal failed, the budget can be severely impacted. Our customers demand the most reliable seals technology can deliver, and our industry has set new standards for seal performance. Conventional O-ring seals no longer meet application demands and industry standards. In order to maintain complete control over the quality and performance of our elastomer seals, FMC Energy Systems has made a substantial investment in an Elastomer Laboratory dedicated to the development of new and improved elastomer seal materials and designs. Field-proven designs developed by FMC Energy Systems include FS-Seals, S-Seals, and Compression Packings with Wire Mesh. At the heart of these premium seal designs are proprietary elastomer compounds formulated to provide the best combination of mechanical properties and chemical resistance to oilfield environments. Molding of FMC Energy Systems’ seal designs using these proprietary compounds is performed at our Nonmetallic Production Facility, located in Houston, Texas. Our experience has demonstrated that in-house elastomer seal manufacture and optimized compounds provide the most reliable combination of mechanical and chemical properties in a premium elastomer seal. This is in contrast to much of the oilfield industry which outsources seal manufacturing. New seal designs demanding new, improved compounds, new molding techniques and testing processes are developed in our Elastomer manufacturing and testing facilities. This assures that FMC Energy Systems brand elastomer seals are not only state-of-the-art design and materials, but rigorously tested for the complete range of customer applications and environmental operating conditions.

In August 1927, brothers Arthur and Kirby Pennick of Houston founded Oil Center Tool (O-C-T) to produce pump liners and rods for the oilfields of East Texas. In 1930, O-C-T introduced a new type of casing head and tubing head that was an immediate success. ➤ O-C-T soon followed these innovations with another first. At the time, completion wellheads (Christmas trees) were assembled and tested on-site – an expensive, time-consuming and dangerous practice. O-C-T had a better idea, along with better completion wellhead components. The company introduced the first factory-assembled and tested Christmas tree, an innovation hailed as a landmark in efficiency, safety and cost-effectiveness. ➤ After only a few years of operation, O-C-T was on its way to setting the standard for the design, manufacture and service of the surface wellhead.

➤ Elastomer SEAL TECHNOLOGY
Higher pressures, well-treatment chemicals, hotter production and longer frac times accelerate the wear and tear on seals, reducing useful life. And if one seal in a wellhead fails, it can blow the budget with lost production and workover time.
Seals Conventional O-ring elastomer seals no longer meet the industry’s stringent design and safety criteria. FMC Surface Wellhead has developed seals that compensate for thermal expansion and contraction, and the larger API casing and tubing tolerances that create increasingly difficult sealing conditions. At the same time, we’ve developed proprietary new elastomers suited to the design parameters of the new FMC Surface Wellhead seals, providing the best combination of mechanical properties and chemical resistance. We design and manufacture our elastomer seals.

Anywhere in the world, in applications ranging from mature low-pressure oilfields of West Texas to critical-service environments from the North Slope to the China Sea, FMC Surface Wellhead is the first name in gate valve technology. We are continually adding value to our superb family of gate valves by listening to your needs, applying engineering improvements to our proven products and making them more cost-effective.
FMC Surface Wellhead offers all Model 100 Series Valves in independent loosevalve configurations for wellhead, tree and manifold applications. Model 100 series valves can also be supplied in composite block configurations for tree and boarding valve applications to suit customer’s special applications and requirements.

➤ Metal-to-Metal
Seals Our oilfield customers look to metal seals as cost-effective technology for extending service life and improving production efficiency. In general, metal seals last longer and provide more reliable service, especially in critical applications. FMC Surface Wellhead’s patented “bump” metal seal is regarded as the technological breakthrough in metal seals for wellheads. We manufacture both self-energized, straight-bore, metal seals and externally energized seals.

FMC KONGSBERG SUBSEA:
SHARED TECHNOLOGICAL ADVANCES
FMC Surface Wellhead was born on land and migrated to the sea. As FMC Energy Systems grew and expanded, the organization was restructured to concentrate like technologies and services into nine highly specialized operating units, including FMC Surface Wellhead. Our sister enterprise, FMC Kongsberg Subsea, which is number one in its global market, grew partly out of the original FMC/OCT wellhead technological group. Today, FMC Surface Wellhead and other FMC Energy Systems operations and their customers benefit from the technology advances developed by FMC’s Energy Systems subsea unit, developing drilling and completion systems for seabed wells, the most hostile of environments for oil and gas production. A notable example, our C22-EG Casing Spool. Its bowl protector retaining subsea technology doesn’t need costly lockdown screws, increasing safety by eliminating the need to work under BOP and potential leak path.

OVERVIEW
T
Standard o Custom The FMC Surface Wellhead Product Line: Standard Flanged Wellheads to Custom-Engineered Systems
Our company is proud to be recognized for its history of technological innovation and its reputation for custom-engineered drilling and completion wellhead systems. But that’s only a narrow slice of what FMC Surface Wellhead offers: In 75 years of listening to your industry, our company has developed a broad spectrum of wellhead drilling and completion components, systems and services. Our C-22 casing head components, for example, introduced in 1962, quickly became the industry standard for this class of product and remain in high regard among company men, drilling engineers and crews, even as we continue to improve and enhance this outstanding line.
For our customers, this broad range of solutions translates into the convenience of relying on a single source – FMC Surface Wellhead – to supply you with exactly what you need for your application, no matter what it is, where it is, how routine or how challenging. For many wells, a standard flanged API wellhead rated at 2,000 psi is the best choice for the budget and risk parameters. For deep critical-service
wells, reliability is the driver: a customengineered project approach may be the best solution. As location, depth, pressures, number of completions per well and other factors complicate the scope, hazards and degree of difficulty of a project, FMC Surface Wellhead is there with a solution that optimizes performance and minimizes your total well cost.

O ff s h o re Designed to Save Time, requires only one major Nipple-Up of the BOP The OBS surface equipment used with SD-1 mudline system has been designed to save time in assembly and disassembly of this unique drilling tool. The major time savings occur when the well is being abandoned. Access to the hanger and packoff/support bushing can be achieved by nippling down the connection at the casing head and lifting the OBS system as a single unit.
Op e r a t i o n s
The OBS surface wellhead has three functions: ➤ To suspend casing risers at the rig ➤ To provide for annulus packoff seals between casing risers ➤ To support the BOP stack When the OBS system is being installed, all of the wellhead spools can be installed as a single unit with the BOP stack on top after installation of the casing head and lowermost packoff/ support bushing. All subsequent casing
CM-1 The CM-1 is a subsea tree utilized to complete subsea wells on mudline suspension systems for shallow waters to 400 feet. ➤ Allows fast-track completions resulting in early production. ➤ Proven, cost effective solution for shallowwater marginal field development. ➤ Allows to tie back to most mudline suspension designs.

hangers and multifunction packoff/support bushings can be installed without nippling down the BOP stack or inserting additional casing spools. In the system shown, additional time savings are achieved through the use of Speedloc II connections on the spools. These connections allow easy and quick access to install hangers and packoff/ support bushings. OBS surface equipment is furnished with clamp connections for 21 1/4˝ 2K, 13 5/8˝ 5K and 13 5/8˝ 10K.

Solutions
Since our days as O-C-T, we’ve led the industry in solutions that save rig time and enhance the safety of your operation. Both those aspects were taken into account when we developed our Diverter Attachment wellhead product offering. One of the inherent dangers of the industry is working under the Diverter/BOP stack when it is being installed or removed. The features we have incorporated in our Diverter Attachment Assemblies greatly minimize the amount of time one is required to spend on the wellhead deck during these operations. Time savings were also a strong consideration taken into account during the development of our Diverter Attachment assemblies. Depending on which design best fits your application, we have incorporated such features as no requirement to wait on cement to set, elimination of “hot work,” ability to land multiple casing strings without nippling down and the speed associated with the installation and removal of the Slip Loc and Speedloc ® quick connections. Depending on which design is selected, the operator could achieve between 6 and 36 hours of rig time-savings.

The wellhead is provided with two load shoulders that allow the operator to land and pack off both conductor and surface casing without ever needing to nipple down. F e a t u re s a n d B e n e f i t s ◆ The wellhead bottom is equipped with a Slip Loc connection and the top with a Speedloc® connection. Both these connections save considerable rig time during installation. ◆ Seals the well bore while drilling out for conductor and surface casing. ◆ If used in conjunction with a mechanical casing cutter, this design eliminates the need for welding; thus there are no longer the dangers associated with “hot work.” Further, adjacent wells do not have to be shut in during installation. ◆ The conductor casing string is landed, packed off and tested prior to cementing. If it is desired that returns be taken across the shale shaker, a flow loop can be installed during the cementing operation. ◆ The surface casing is landed on the upper load shoulder with a fluted hanger for flow by. Once cementing operations are complete, the pack off is run, locked in place and tested prior to nippling down. ◆ The diverter riser assembly is removed and subsequent wellheads installed with the use of the Speedloc® connection, which is designed to save valuable rig time. ◆ Available in Slip Loc or butt-weld prep for 30˝, 26˝ & 24˝ drive pipe.

Clamps
Description: To reduce installation time and wellhead equipment size, FMC Surface Wellhead uses clamp devices in place of flange connections for wellheads. The Speedloc ® Clamp consists of a series of segments which are mechanically isolated from one another, permitting each segment to act as an independent clamp. These clamp segments pull the integral mating hubs together as the nuts are tightened. The contact surface between the segments and the hubs acts as a ramp to maximize vertical clamping force.
FMC Surface Wellhead’s integral Speedloc Clamps can be pre-installed on wellheads, BOPs and other drill-thru components with no rig assembly time required. One person can make up all sizes of Speedloc Clamps in less than 10 minutes. The increased strength and reliability of Speedloc Segmented Clamps over two-piece clamps help ensure safety in the field by greatly reducing the risk of a failure. Other factors inherent in the design of the Speedloc Clamp that help maximize personnel and rig safety include the elimination of special tools, handling devices and loose parts, minimizing time and exposure of service personnel in the area of the wellhead. FMC Surface Wellhead currently offers two versions of the Speedloc design:
Speedloc I: Proven worldwide, Speedloc® Clamps are available in nominal sizes from 7 1/16 to 21 1/4 inches for standard and sour-gas services to 20,000 psi. They provide distinct mechanical and operational advantages over alternative connectors, and are ideal for high-temperature applications. Straight-bore metal seal
Speedloc-I Segmented Clamps use FMC Surface Wellhead’s patented straight-bore metal seal (SBMS) rather than the standard API seal (R, RX or BX) found in other wellhead connectors. The SBMS seal is preloaded radially during assembly as the clamp segments pull the mating hubs together. Therefore, the Speedloc Clamp does not require further vertical preload to generate a seal. Sealing integrity is maintained by radial compression of the seal against the machine surfaces of the seal pocket. Fluctuations in vertical end loads and externally applied bending moments do not affect the function of the seal. Speedloc-I Clamps provide high bending moment and shear-resistance capacities, far exceeding conventional two-piece clamps in strength. Under well pressure conditions, the total load is distributed equally between the Speedloc-I Clamp’s studs, with only moderate torque required for full stud preload. The loss of a single Speedloc-I Clamp stud results in only 8.3% drop in clamp preload, therefore maintaining 91.7% of the installed connector’s preload. In contrast, if one stud fails on a two-piece clamp, failure of the entire clamp could occur.

Speedloc II: Proven worldwide, Speedloc-II Clamps are available in sizes from 7 1/16 to 21 1/4 inches for standard or sour-gas services to 20,000 psi, 0oF to 250oF, providing mechanical and operational advantages over other connectors. Superior “clamping” by design
The Speedloc-II Clamp consists of a series of segments which are mechanically isolated from one another, permitting each segment to act as an independent clamp. The Speedloc II uses a travel nut with a retainer bolt to secure the segments onto the hub. When the travel nuts are being loosened, the retainer bolts keep the nuts and segments together, causing the nuts to positively retract the segments. The Speedloc-II nut threads are coated to provide a lower coefficient of friction, reducing make-up torque and dramatically increasing thread life. The result: you get enhanced clamping and higher end load capacities in a compact, preassembled design with significant safety advantages. Mates with conventional clamp hubs

Clamps
FMC Surface Wellhead’s Speedloc-II Clamps mate to conventional clamp hubs using API RX or BX ring gaskets. The design allows for interface between FMC Surface Wellhead and existing conventional clamp hub equipment. The Speedloc II can also be provided with FMC Surface Wellhead’s straight-bore metal seal (SBMS) for special applications. Speedloc-II Clamps maximize strength by distributing total load equally between the clamp’s studs, with only moderate torque required for full preload. Speedloc-II Clamps typically have 12 or 16 studs, depending on the size, versus two or four studs in conventional clamps. As a result, the Speedloc II’s studs are smaller in diameter for the same load-bearing capacity, and require significantly less torque for installation.

TC-ET The TC-ET tubing head has one aligning pin and accepts all TC-Series tubing hangers and packoffs except the TC-60 dual-split hanger. It can be upgraded to a TC-60-ET by adding two aligning pins at an FMC Energy Systems facility.
The TC-60-ET is the most versatile tubing head in the oilfield. It has three aligning pins and is compatible with all TC-Series tubing hangers and packoffs, including the TC-60 dual-split hanger. When last-minute completion changes are possible, the T-60-ET is a good investment because no shop modification is needed to adapt it to any type of tubing completion.
TC-WD-ET The TC-WD-ET tubing head has an internal wedge that is used for alignment on specific TC-Series tubing hangers. This particular design allows for alignment of multiple-string tubing hangers without external manipulation methods. TC-WD-ET tubing hangers are generally considered specific to particular customers’ requirements and can be run only in the TC-WD-ET tubing head. FMC hangers that normally are aligned with pins (TC or TC-60 type) will not function in the TC-WD-ET head.
A l t e r n a t i ve Tu b i n g H e a d C o n f i g u r a t i o n s Bottom Connections Bolt-through flange, studded flange and clamp-hub connections are available. The type and pressure rating used must match the top flange of the previous casing spool or crossover flange. Bolt-through flange connections are the most popular and economical type of connection in certain parts of the world. Clamp-hub connections are sometimes specified, because they are much faster to make up and because they reduce the diameter and weight of the assembly when space limitations are present.
Top Connections FMC Surface Wellhead tubing heads have either bolt-through flange or clamp-hub top connections, which are compatible with all FMC tubing head adapters. The producing pressure of the well normally determines the pressure rating of the top connection.
Lockdown Screws Most FMC Surface Wellhead Series tubing heads have a series of lockdown screws in the top flange (unless customer or application requires otherwise). These lockdown screws have three functions: ◆ to actuate compression-type hanger or packoff seals ◆ to lock down the hanger or packoff to prevent movement caused by thermal expansion of the tubing string during production ◆ to lock down the hanger in the event of annulus pressure NOTES: ◆
Where customer preferences or applications do not allow the use of lockdown screws, internally locking mechanisms are utilized. See section on Completion Solutions.

A l t e r n a t i ve Tu b i n g H e a d C o n f i g u r a t i o n s Bottom-Bowl Packoffs (secondary seals) Tubing head bottom-bowl packoffs are used to seal around the production casing stub in the bottom bowl of the tubing head. They are often referred to as “secondary seals.” The various packoff types are described below:
Double FS Seals This design consists of two elastomeric-shaped seals located in grooves in the bottom of the tubing head. A seal is achieved by interference of the seal with the outside diameter of the casing and the bottom or OD of its retaining groove. A spring molded in each inside corner of the seal provides an anti-extrusion mechanism when sealing against pressure by bridging the gap between the tubing outside diameter and casing head seal bore. The shape of the seal allows it flexibility to maintain sealing interference with the large variations in tubing outside diameter.
PI Seals These seals consist of a T-cap seal element, nonextrusion rings and a receiver ring. These components will fit the HPE bottom prep configuration. The PI seal is designed for use up to 15,000 psi working pressure and temperatures up to 75 o F or as low as -50 o F, depending on the elastomer selected. It provides the proper compression and squeeze even with the larger API casing tolerances. The design effectively intensifies the annulus pressure and thus the internal stress in the elastomer to minimize the effects of explosive decompression.
SBMS-II Seals This metal-to-metal seal consists of a “U”-shaped ring with a “bump” sealing surface at the outside and inside legs of the “U.” When installed, the entry ramp compresses the legs of the “U” inward and creates contact stress in each “bump” that provides the seal. This seal requires the casing stub OD to be field machined after the casing is hung to provide the proper sealing tolerances and surface finish. This is accomplished with a portable pneumatic-driven tool. It is good for temperatures ranging from -75 o F to 1200 o F.
RCMS Seals The Rough Casing Metal Seal (RCMS) is designed to use up to 20,000 psi. This seal does not require special machining of the casing stub; is compatible with temperatures from -20 o F to 350 o F in corrosive environments; does not require special installation tools and is simple to install; is NACE compatible; is compatible with casing spool and tubing spool strength; is compatible with casing string strength properties. NOTES: ◆ TC-Series packoffs are usually installed in the tubing head prior to shipment. FMC tubing heads are also available with threaded bottom preparations in some sizes and pressure ratings.

Tu b i n g H e a d A d a p t e r s Description: The tubing head adapter provides a transition between the Christmas tree and the tubing head. The bottom adapter connection matches the tubing head, and the top adapter connection matches the tree. Tubing head adapters are available for all types of single- and multiple-string completions, including those using electric submersible pumps, packers, downhole control valves and gas lift valves. These adapters come with threaded, flanged or studded-flanged top connections. Most tubing head adapters are available with hydraulic supply inlets for downhole control lines. If the customer requires, FMC Surface Wellhead also supplies various types of adapters that will accommodate continuous control-line capabilities. Following you will find the most generally used.
Basic Adapters A4
Dual-Seal Bore Adapters A-4-D
Single-Seal Bore Adapter A4
ESP Adapter
Basic Adapters They provide only a transition between the tubing head and the tree. These adapters do not hang the tubing or provide a controlled seal bore. Basic tubing head adapters have a smooth seal bore and are used when tubing is suspended from the tubing hanger. They are designed for low-pressure completions where downhole line or tubing strings manipulation are not required. The basic adapter is normally installed with the tree after tubing is run.
Features and Benefits ◆ Simple transition piece between the tubing head and the tree ◆ Used with a TC-1A tubing hanger ◆ Available with threaded, flanged or studded top connection
Seal Bore Adapters Seal bore adapters have the inside diameter machined to provide a controlled seal bore for an extended-neck tubing hanger or a seal nipple. They are available with a test port and/or a hydraulic supply inlet for downhole control lines. Like basic adapters, they are normally installed with the tree.
Features and Benefits ◆ Provides a seal bore for the TC-1A-ENS extended neck (Single-Seal Bore) ◆ Provides seal bores for the seal nipples on dual-completion tubing hangers (Dual-Seal Bore) ◆ Available with SCSSV control line inlets ◆ Studded top connection only
ESP Adapters ESP adapters have seal bores to accommodate both a tubing hanger neck seal and an electrical power feed-thru device. Standard ESP adapters are equipped with rotating flanges to mate to the tubing head, minimizing concerns over alignment issues. Positive alignment can be obtained through the use of optional features in the mating ESP hanger. ESP adapters can be supplied to match standard tubing heads rated to 3,000 and 5,000 psi working pressure.

Features and Benefits ◆ Provides sealing bore for a variety of electrical feed-thru configurations, including penetrators, cable packoffs and continuous feed-thru penetrator mandrels. ◆ Provides reliable seal bores for tubing hanger neck or seal sleeves. ◆ Provides rotating attachment flange for ease of alignment to ESP hanger and tubing head flange.
Tubing Suspension Adapter B-2-S
Tubing Coupling Adapter BO-2
Tubing Coupling Adapter BO-10
Tubing Suspension Adapters These adapters provide a means to hang the tubing via tubing threads machined in the lower-connection inside diameter. The tubing threads can be used to suspend tubing when an operator wants to reciprocate tubing, but does not require a back-pressure valve in the tubing hanger. These adapters do not provide a seal. They are normally used on low-pressure completions with a wraparound packoff or stripper.
Coupling Adapters Coupling adapters provide a means to suspend the tubing in conjunction with a special coupling. They provide a lower connection for the tubing head and an upper connection for the tree and are used with a tubing coupling, which suspends the tubing and accepts a back-pressure valve. It is used for high-pressure completions where the operator wants to manipulate tubing through a wraparound packoff or stripper and needs a back-pressure valve and/or a hydraulic supply inlet for downhole control lines. An ACME thread is machined into the adapter’s bottom inside diameter to be utilized in conjunction with the coupling to hang the tubing. Then it can be screwed onto the coupling. When a tree is trimmed for critical service, a coupling adapter with a coupling nut is available to prevent possible galling of threads between the adapter and coupling on makeup.
BO-2 Coupling
BO-10 Coupling
Features and Benefits ◆ Used with the BO-2 tubing coupling ◆ Adapter makes up to the tree. ◆ Entire assembly is installed by rotating it onto the coupling. ◆ Studded top connection only

Description: Tubing hangers are installed in the top bowl of a tubing head. Tubing hangers both suspend tubing and provide a primary annulus seal between the tubing and production casing. Hangers are run through the blowout preventers and are landed in the top bowl of the tubing head. Tubing hangers are available for any type of tubing completion. Tubing hangers also act as a means to access and manipulate additional smaller tubing lines that are utilized downhole and extended to the surface on the outside of the tubing string or strings. Packoffs allow tubing string manipulation for setting packers or displacing fluid while sealing the annulus between the tubing and the production casing.
FMC Surface Wellhead TC-Series tubing hangers are available for any type of single- or multiplestring tubing completion, including those requiring packers, subsurface safety valves, gas-lift valves and electric submersible pumps. All FMC Surface Wellhead hangers can be run through the blowout preventers, allowing the well to be secured before the preventers are removed. Most TC-Series tubing hangers accept a back-pressure valve, which seals the tubing bore. These BPV profiles may be of FMC Surface Wellhead design or they may be of another manufacturer’s design, depending upon the customer’s requirements. Some hangers are ported for hydraulic control lines, downhole safety valves or other equipment as required by the customer.
S i n g l e - S t r i n g Tu b i n g H a n g e r s Most TC-Series single-string hangers do not require aligning pins and are compatible with any TCSeries tubing head. Generally speaking, alignment pins will not be required unless there is a need to orient a hanger a particular way. An example of this might be when an additional line is being run with the tubing string and needs to be ported through a particular position in the tubing spool.
TC-1A
TC-1W
TC-1A The TC-1A is a threaded tubing hanger with an integral compression-type annulus seal that is actuated by string weight and or by lockdown screws. This hanger is also known as a threaded mandrel-type hanger and is considered one of the most basic and least expensive hangers in FMC Surface Wellhead’s TC product line.
TC-1W The TC-1W is a split, wraparound packoff that allows tubing-string manipulation to displace fluid while maintaining complete control of annular pressure. Like all TC-Series packoffs, tubing string weight must be suspended from a tubing suspension adapter or coupling adapter. The TC-1W has a compression-type seal which is actuated by lockdown screws.

BO-2 Coupling
Page 13
BO-10 Coupling
TC-B-EC
BO-2 Coupling A BO-2 coupling-type tubing hanger uses a one-piece coupling that is externally threaded with a coarse heavy-duty ACME thread. Internally the coupling will provide tubing threads in the top and bottom along with a back-pressure valve groove. The BO-2 coupling is attached to the last tubing joint and is run in conjunction with a TC-1W wraparound-type packoff. Ultimately, the BO-2 coupling is made up into a BO-2 adapter that is assembled on the bottom of the Christmas tree.
Features and Benefits ◆ Threaded coupling is used in conjunction with the BO-2 tubing head adapter for high-pressure completions requiring both string manipulation with BOP protection and SCSSV control lines. ◆ Requires a TC-1W wraparound annulus seal. ◆ FMC Surface Wellhead “ISA” back-pressure valve preparation is standard.
BO-10 Coupling The BO-10 coupling-type tubing hanger is generally utilized on completions demanding higher completion shut-in pressures. This hanger is a coupling by design but also incorporates a separate rotating, ACME-threaded locking nut. This design is also attached to the last tubing joint, and is run in conjunction with a TC-1W wraparound-type packoff. Ultimately, the BO-10 coupling is made up into a BO-10 adapter that is assembled on the bottom of the Christmas tree.
Features and Benefits ◆ Coupling nut allows the BO-10 coupling to be installed without rotation of the tree, making it the choice for heavy trees or where dissimilar metals could cause galling problems. ◆ Requires a TC-1W for annulus seal.
TC ESP The TC ESP hanger is dual-ported, with one port designed to accept a single production tubing string. The second port is designed to accommodate the electrical conductors that pass the current between the surface cable and the subsurface cable that goes to the pump. The TC ESP hanger is designed for 7 1/16"- 3,000/5,000 and 11"- 3,000/5,000 flange sizes. We standardized on EUE thread configurations. Nevertheless, additional thread profiles and different configurations can be supplied. While configurations and designs may differ with customer requirements, the basic design concepts stay the same.
Features and Benefits ◆ Has redundant “B” Type “S” seals on the body of the hanger. ◆ No alignment groove. It has an attachable alignment plate on the bottom of the hanger when alignment is required. ◆ No threads for penetrator makeup. Penetrator will be equipped with a “jam” nut on the bottom of the penetrator to hold in the hanger body.
Benefits ◆ Can easily convert an existing flowing well to an ESP without the need to change out the tubing head. Can utilize a TCM-type tubing head. ◆ Can convert a finished hanger with a QCI penetrator profile to accept a BIW penetrator.

Penetrator does not require rotation for makeup. Eliminates the potential of seal or thread damage when rotation of penetrator is necessary.
Multiple-String Tubing Hangers and Packoffs TC-Series multiple-string hangers and packoffs permit the independent suspension and sealing of multiple-tubing strings, allowing simultaneous production or injection to or from separate zones. They require one or two aligning pins in the tubing head bowl and are compatible with either TC or TC-60 tubing heads. The TC-60 split-type hanger may be run only in the TC-60 tubing head.
TC-60 Dual-Split Hanger
TC-2C
TC-60 Dual-Split Hanger The TC dual-split hanger is an easy-to-run split hanger with an integral compression-type packoff. The packoff seal is actuated by lockdown screws before the blowout preventers are removed. No plastic injection is required. With the TC-60 dual-split hanger, tubing strings can be run and pulled independently, allowing maximum clearance for gas-lift or subsurface safety valves. Each segment accepts a back-pressure valve and is available with control-line preparations for surface-controlled subsurface safety valves.
Features ◆ Allows tubing string to be run and pulled independently. ◆ Provides for maximum clearance for gas-lift valves, SCSSV and packers. ◆ FMC Surface Wellhead “ISA” back-pressure-valve preparation in each hanger half is standard. ◆ Tubing head must have the dual TC-60 aligning pins.

Alberta (Canada) There are moments when the challenge is not the environment, the pressure or the reliability. Shallow, marginal low-pressure well production dictates a very tight budget. The oil company then needs to maximize its use of customer property and to utilize the adequate technology to match its application. There is not extra cash for any luxury beyond the basic requirements. At FMC Surface Wellhead we listened to market situations and decided to develop our FH line with tapered bowl and exclusive elastomer seal design to stay “on budget.” Features and Benefits ◆ Tapered configuration matching the market needs ◆ Elastomeric seal ◆ Low pressure ◆ Material Trim AA ◆ Pressures up to 2,000 psi o o ◆ Temperature –50 F to 250 F

Time Optimization (DTO) System
Rocky Mountains (United States) Our customer’s infield drilling program needed to minimize his rig time for multiple shallow wells (with surface casing pressures less than 5,000 psi) and to improve safety. FMC Surface Wellhead’s solution was the DTO ® wellhead, which delivers significant time savings by eliminating a number of steps in the traditional drilling process and reducing time required for other steps. The ideal situation for using the DTO would be a single rig that’s drilling multiple consecutive wells by using a common casing program. Each rig is outfitted with a DTO diverter connector fabricated into a diverter riser. The assembly stays with the rig for the drilling project, and it is used on each well. A DTO drilling spool connector is assembled into the rig BOP and is moved with the rig from well to well. Features and Benefits ◆ Eliminates steps in the drilling process. ◆ Offers time savings during nipple up/down of the BOP’s stack, landing casing hanger and installing the tubing head. ◆ Increases safety by eliminating the need for cutting torches and hammer wrenches. ◆ Locking ring design on drilling spool provides 360 degrees engagement to increase load capacity and reduce fatigue. ◆ Contingency systems for stuck pipe retains system benefits and time savings. ◆ Tests production casing seals prior to removal of BOP. ◆ Load capacity of surface casing hanger exceeds joint strength.

China Sea (China) This project in the China Sea’s Ya Cheng field, which supplies gas energy to Hong Kong, presented the challenges of critical conditions: high corrosive, high temperature, fire resistant, severe weather, large-bore production, high reliability and a long life cycle to reduce the need for workovers. Our state-ofthe-art “dry tree” system, the UWD-15, is an excellent example of our quest to design highly reliable wellheads for difficult environments and conditions and still contain costs. Developed out of our subsea wellhead technology, the UWD-15 is a 15,000 psi wellhead that combines advanced technology for high-pressure and hazardous-service environments. All seals are metal-tometal, with the UWD-15 packoff providing the basis for annular sealing. This packoff does not rely on the tubing hanger weight to energize and can be removed separately from the tubing hanger. It utilizes an SBMS seal at the tubing hanger neck as standard. The seat is recessed to help ensure that the seal contact surface is not damaged when the packoff is installed. The design includes a fire-safe envelope for the upper master valve to the annulus A. Features and Benefits ◆ The 15,000 psi wp UWD-15 Wellhead System minimizes leak path to the environment. ◆ Has a metal-to-metal seal, SBMS technology. ◆ Includes internal latch. ◆ Has major connections with Speedloc ®. ◆ Offers field-proven advanced technology. ◆ Standard subsea tooling facilitates availability and learning processes.

Gulf of Campeche (Mexico) Injecting 1.2 million cubic feet of nitrogen per day into a formation through a 9˝ bore is a major challenge to face with traditional solutions. The limited available height and weight on the platform plus the handling of a 9˝ Christmas tree during installation and workover ruled out a conventional production wellhead solution. Our engineers who have platform working experience understood better than other suppliers the operational challenge, and proposed the first horizontal wellhead tree system of its size in the Gulf of Mexico. Features and Benefits ◆ Full 9˝ bore system. ◆ Allows workover without removing Christmas tree. ◆ It has hydraulic or pneumatic valves. ◆ Wire Mesh FMC Surface Wellhead seal technology. ◆ Allows drilling through the tubing hanger. ◆ Maximizes platform’s available surface.
Side-By-Side
(SXS)® System
Java Sea (Indonesia) Fragmented reservoirs requiring multiple interventions are a major challenge due to the reduced space on platforms, especially when, as in this example, you need to complete (or abandon) wells and perform interventions without disturbing adjacent wells. For such challenges, FMC Surface Wellhead has developed a Side-By-Side (SXS) Wellhead System for optimization of space on new platforms or workovers on existing platforms. The SXS also accommodates configurations involving a combination of single and dual completions inside a single conductor. Features and Benefits ◆ Allows installing either a 2-in-1 or 3-in-1 well configuration inside a single conductor, sized from 26˝ OD onwards to suit requirements. ◆ Eliminates the need for additional conductor pipe. This creates up-front savings and reduces abandonment costs. ◆ Allows the use of standard drill-bit sizes. ◆ Independent Tubing Heads (Unihead ®) allow greatest flexibility in choosing wells to complete or abandon and to perform independent intervention, entry and re-entry without disturbing adjacent wells or flow lines. The wellheads are installed with full BOP protection. This system promotes time saving through batch drilling and drilling with reduced rig move time. ◆ Maximize platform size and the use of well slots on the platform. For existing wells, the SXS wellhead maximizes the use of existing spare well slots.

System
Gulf of Mexico (USA) By far the most experienced suppliers of TLP/SPAR systems in the Gulf of Mexico, we also installed the deepest and most fire-resistant SPAR in the Gulf. As certain platforms are designed to move with water action, every element connected to the sea floor becomes an integral part of a dynamic system and requires specialized wellhead solutions like our TLP/SPAR systems. From the initial stages of your project, we can help you decide to go with a “wet” or a “dry” tree. Example: If you’re facing a fragmented reservoir offshore and must execute multiple interventions, economics indicate a surface tree. FMC Surface Wellhead installed the first TLP/SPAR system in the Gulf of Mexico during the 1980s and has been the leader in this technology since, installing more systems worldwide than our competitors combined. Features and Benefits Special slip-lock assembly securely attaches wellhead to riser. ◆ Straight-bore metal seal (SBMS) provides a more secure seal against heavy sideloads that can be generated by wave activity. ◆ More compact profile reduces vertical space requirement. ◆ New tubing head design provides full metal-to-metal seal. ◆ Special plug and lubricator adapter provides easy vertical access to the gas-lift string. ◆ SCSSV and inhibitor lines exit through the upper wellhead connection. ◆

A wellhead is as good as its valves, and FMC Surface Wellhead’s valves are as good as it gets.
S e r i e s 1 0 0 G a t e Va l v e s FMC Surface Wellhead’s Series 100 Gate Valves have successfully met customer demands for performance, endurance and ease of maintenance since their introduction in 1984. Available in working pressures from 2,000 to 20,000 psi, these metal-seal gate valves provide bubble-tight operation throughout their rated pressure and temperature ranges. Sizes, configurations and materials are available for virtually any application. Model 100 Series Valves by far exceed the requirements of API 6A. Model 120, Model 125, Model 130, Model 135, Model 160 and Model VLT have been qualified in excess of Appendix F for material class AA to HH and temperature rating –75 to 400oF. An additional 300 endurance cycles are applied to simulate 20 years of life expectancy. Series 100 gate valves come in trims for a complete range of water, oil and gas services – including corrosive, high-temperature, subsea, arctic, sand and steam.
Belleville spring
Metal-to-Metal seal design FMC Surface Wellhead’s Series 100 gate valves use a precision-machined floating slab gate and seat design that provides a fully energized metal-to-metal seal between the gate and seat surfaces at all times. A Belleville spring behind each seat keeps the seat in contact with the gate to ensure effective sealing at very low pressures. These fully symmetrical valves effectively seal against flow in either direction. Even though the seats “float” in their respective pockets, the downstream seat still creates a metal-to-metal seal against the body when the valve is closed. The back face of each seat has FMC Surface Wellhead’s exclusive double-bump profile (right figure). As the valve closes, line pressure forces the gate against the downstream seat, which in turn is driven against the back of the pocket, where the double bumps form a gas-tight, metal-to-metal seal.

L O N G L I F E E X P E C TA N C Y A N D R E L I A B L E O P E R AT I O N Key features to ensure reliability for the life of the valve are: Metal-to-metal sealed bonnet assembly: Separate weather seals on the Series 100 valve bonnet assemblies isolate the stem, stem bearings, packing nut and other internal components from external environment. Heavy-duty stem bearings: Dual stem bearings support all axial loading on the stem. These low-friction, tapered roller bearings also help reduce operating torque. High-strength stem threads: Standard ACME threads offer high shear strength and high contact area for maximum endurance. A separate gate-lift nut contains the mating threads instead of the gate itself. This flexible design permits optimum stem/lift nut material combinations and allows the gate to float independently from the stem. In the unlikely event of thread damage, only the nut or stem needs to be replaced. Stem shear pin: The stem is protected against accidental twist-off by the stem shear-pin. The pin can be quickly replaced without disassembling the valve bonnet. Close-fitting gate guides: Stainless-steel gate guides stay within a few thousands of an inch of the gate, acting as mud skirts to minimize well fluids, sand and mud from entering the valve body as the gate opens and closes.

The actuator is fail-safe/fail-close because it will close with the loss of control pressure, with or without pressure in the valve body. Heavy-duty coated spring package is designed to provide closing force at zero or low pressure. Actuators are designed with back-seat capability. Designed to accept our full range of accessories, i.e., stem protectors, fusible lockout caps, etc. Quick-disconnect design and spring box design reduces time required during maintenance operations.
HP– PN Pneumatic Piston Actuator mounted on a reverse-acting gate valve. The HP-PN Pneumatic Actuator is designed to be failsafe and fail-close. When installed as part of a safety system, it will automatically close with the loss of control pressure and will open automatically when the control pressure is restored.

Functions ◆ ◆ ◆ ◆
◆ ◆
Actuators are used on secondary master valve and/or wing valve of a Christmas tree, flow lines, header valves, gathering lines and pipelines. As part of a surface safety system, the actuator will shut off flow from the well in the event of a catastrophic event. The HP-PN surface safety valve is a pneumatic-controlled actuator that is operated by an air or gas source. Pneumatic pressure acting on the piston holds the valve open. Loss of pneumatic pressure in the actuator’s cylinder allows the well or flowline pressure acting on the area of the lower stem to force the stem and gate closed. Pneumatic actuators can be used in both gas and oil wells. Care should be taken when using pneumatic actuators on high-pressure and/or large-bore applications. One of the opening characteristics of a pneumatic actuator is that once sufficient force is generated to break the differential, the valve will instantaneously go from closed to full open. This causes a slam-open effect that can cause damage to gates and seats. This can potentially damage the actuator. The following are some methods to reduce this potential problem: o Reduce the differential pressure across the valve. o Reduce the volume of air in the cylinder. o Dampener mechanism. o Use of a hydraulic actuator is considered the best option.
Benefits ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆
Loss of control pressure above the piston will cause the actuator to close the valve. In the event of a fire, the metal-to-metal seal between bonnet and lower stem acts as a secondary seal if the stem packing is damaged. Has a back-seat test port and packing leak detection port. A relief valve on the cylinder prevents overpressurization. Large piston area permits use of low-pressure air or gas control systems. Has a rising stem for visual indication. Pneumatic cylinder and piston are electrolysis nickel plated for corrosion resistance, reducing repair cost. Upper stem packing is easily removed. P N E U M A T I C

Identification The HP-PN Pneumatic Piston Actuator assembly includes the bonnet and the actuator assembly. The HP-PN actuator will be sized to open the valve against full differential with the available control pressure. The designation for the FMC Surface Wellhead pneumatic piston actuator is four alpha characters followed by two numeric characters. For example, the designator for a pneumatic piston actuator is HP-PN38. The HP is the product identifier; the PN references pneumatic piston, and the 38 refers to the piston size. A given piston size can be used on a number of valve sizes.

HP– HY Hydraulic Piston Actuator reverse-acting gate valve. The HP-HY Hydraulic Actuator is designed to be fail-safe and failclose. When installed as part of a safety system, it will automatically close with the loss of control pressure and will open automatically when the control pressure is restored.
Functions ◆ ◆ ◆ ◆
◆
The actuators are used on secondary master valve and/or wing valve of Christmas tree, flow lines, header valves, gathering lines and pipelines. As part of a surface safety system, the actuator will shut off flow from the well in the event of a catastrophic event. The HP-HY surface safety valve is a hydraulically controlled actuator that is operated by a closed hydraulic system completely independent of well fluids and pressure. Hydraulic pressure acting on the piston holds the valve open. Loss of hydraulic pressure in the actuator cylinder allows the well or flowline pressure acting on the area of the lower stems to force the stem and gate closed. Recommended for use in high-pressure and/or large-bore applications.

HP– HYW Hydraulic Wire Shear Actuator
Functions ◆ ◆ ◆ ◆
The actuators are used on the secondary master valve. They are the primary surface safety device during a wireline operation. As part of a surface safety system, the actuator will shear the wireline and seal off the flow from the well in the event of a catastrophic event. The HP-HYW surface safety valve is a hydraulically controlled actuator that is operated by a closed hydraulic system completely independent of well fluids and pressure. Hydraulic pressure acting on the piston holds the valve open. Loss of hydraulic pressure in the actuators cylinder allows the well or flowline pressure acting on the area of the lower stems to force the stem and gate closed. The spring package is sized to cut a specific size of wireline.
F e a t u re s ◆ ◆ ◆ ◆
Coiled spring design provides cutting force. Control line port can be rotated 360°. Hydraulic section is resistant to corrosion. Has a quick-disconnect clamp.

Description: The Type HP-HYW Hydraulic Actuator is a ratio-piston-type actuator mounted on a reverse-acting gate valve. The HP-HYW Hydraulic Wire Shear Actuator is designed to be failsafe and fail-close. The coiled multi-spring assembly provides the added shear force. When installed as part of a safety system, it will automatically close with the loss of control pressure and will open automatically when the control pressure is restored. The wire shear actuator becomes the primary surface safety device during wireline operations. Should an emergency take place while the wireline tool string is in the well, the wire shear actuator is designed to shear the wire and seal off the flow of the well.

◆ ◆ ◆ ◆ ◆
In the event of a fire, the metal-to-metal seal between bonnet and lower stem acts as a secondary seal if the stem packing is damaged. Has a back-seat test port and packing leak detection port. Spring packages are designed to fit customer application. FMC Surface Wellhead has provided spring packages to cut various-sized wires. We provide a North Sea operator a wire shear spring package to cut 7/16˝ braided line (shear force required was 22,400 lbs.). Oil port can be rotated 360 degrees for easy alignment of power-source control line. Has a lifting eye to facilitate removing the actuator when mounted horizontally. Two bonnet types are available to cover a wide range of applications. The Type A bonnet is the extended version, and the Type B bonnet is the flush-mounted version. Nipoloy process (electrolysis nickel) is used on hydraulic cylinder for corrosion resistance. Hydraulic piston is hard chromed for corrosion resistance. H Y D R A U L I C

Seal echnology Seals are critical for achieving reliable pressure integrity in wellhead equipment. FMC Energy Systems is proud of our sealing designs, and we would like to share our seal technology with you so you can take it into account next time you specify your equipment. Common oilfield elastomers are sufficiently reliable for low-pressure, normal-service oil and gas wells, and special elastomer compounds and designs are available for critical-service wells. However, all elastomer compounds lose some of their sealing effectiveness over time, with the rate of degradation dependent on environment. Sometimes a metal seal option can be a cost-effective way to increase service life and improve production efficiencies. FMC Energy Systems has the expertise to help you decide the best fit (elastomer or metal) for your application.

A number of the more conventional wellhead seals can no longer meet the new stringent design-acceptance criteria, such as the larger API casing and tubing OD tolerances now allowed by API Spec-5CT. For example, the conventional O-ring seal is very limited in its ability to bridge large extrusion gaps and remain intact without some kind of antiextrusion device. In addition, some seal designs cannot keep a bubble-tight seal over the wide temperature ranges and large pressure variations encountered. FMC Energy Systems’ response to these new API requirements addresses the limitations found in traditional interference and slab-packing applications with the following key design features: ◆ Seals meet API Spec. 6A, Appendix F, Performance Requirement Level Two (PR-2) pressure and temperature cycle testing. ◆ All seal designs utilize one of the FMC proprietary elastomeric compounds. These seal compounds are rated for all API material classes, including class HH (H2S/CO2 service), and are also amine resistant. ◆ Antiextrusion devices are incorporated into each type of seal design to compensate for thermal expansion/contraction of the seal element and for installation clearances. ◆ All seal elements and antiextrusion components are continuous. ◆ Antiextrusion devices are integrally molded into the seal element, making them easier to install and more durable. ◆ All seals are designed to provide proper squeeze, volume fill and stretch under all API/FMC tolerance conditions, i.e., the largest diametric gap possible and the worst-case misalignment of sealing surfaces.

FMC Energy Systems’ patented “bump” seal design has addressed many issues traditionally associated with metal seals to become a technological breakthrough for wellhead equipment. FMC Energy Systems’ metal seals are rugged enough for the oilfield operation, have simple installation procedures, are easily tested after installation and are reusable in most applications. In most applications FMC Energy Systems metal seals are “self energizing” and do not rely on a wedging action, suspended weight or flange make-up force to affect a seal. The seal is “pressure assisted” and can work in any pressure. ◆ Meet API Spec. 6A, Appendix F, Performance Requirement Level Two (PR-2) pressure and temperature cycle testing. ◆ Are rated for all API material classes, including class HH (H2S/CO2 service) and are also amine resistant. ◆ Can be made from almost any high-strength steel or corrosion-resistant alloy, for use in extreme corrosive services. ◆ Work in all temperature ranges, from -75°F arctic service to 1200°F for fire-resistant applications. ◆ Are easy to install and test and can withstand standard oilfield handling. ◆ Do not deform (crush) metal, either on the seal or on the mating surfaces, so both are normally reusable, minimizing workover costs.

E lastomer Seals S-Seal The S-Seal is designed to provide reliable sealing between machined components. It is a versatile and reliable seal in cyclic high-pressure and -temperature applications, where conventional interference-type seals (O-rings, belt packing, dovetail, etc.) are typically inadequate. The S-Seal is an interference-type seal utilizing metal coil springs molded integrally into the exposed seal corners as antiextrusion devices. Another important feature of the FMC design is the use of a “continuous” coil spring, which eliminates weak points around the seal’s circumference. The S-Seal can be used in many applications where there is a controlled/machined gap between the sealing bore and shaft; for example, a mandrel hanger neck and tubing head adapter bore. There are both O.D. and I.D. applications of the S-Seal, with sizes available in nominal diameters up to 20˝. The S-Seal design can be rated up to 10,000 psi working pressure and a 0° to 250°F temperature range for all sizes. Special designs allow qualification to 15,000 psi working pressure and 300°F.
S-Seal
FS-Seal The FS-Seal has been designed to seal against rough casing where wide tolerances and varying surface finishes create difficult sealing conditions. It is utilized as a large cross-section interference seal to bridge large extrusion gaps associated with sealing on rough mill casing. The bump provides higher sealing contact stresses, while the curved recess on the back of the seal controls the amount of compression (squeeze) on the seal element by allowing it to deflect outward when sealing against a larger-than-normal outer-casing diameter or an out-of-round section of casing. The FS-Seal can be supplied integral to a casing-head bottom preparation as a 1-FS (one seal with no secondary) or 2-FS (two seals with one secondary) packoff. It can also be supplied as a separate 4-S packoff bushing, which incorporates a secondary S-Seal on the bushing OD and a secondary FS-Seal on the ID. The FS-Seal is available for 4 1/2˝ to 30˝ pipe sizes. The FS-Seal is rated to 10,000 psi working pressure and a 0° to 250°F temperature range for sizes up to 16˝, while the larger sizes are rated to 5,000 psi working pressure.

Compression Packing with Wire Mesh This design is mechanically energized by lockdown screws after assembly and utilizes integrally molded wire mesh rings on top and bottom of the elastomeric element to increase extrusion resistance. Its design and elastomer compound enable excellent temperature and environmental resistance. It can be used up to 15,000 psi working pressure and a -50° to 250°F temperature range. The wire mesh is annealed 316 stainless-steel material for corrosion resistance.

Elastomeric Sealing Element
PI Seal The FMC PI Seal design is an extremely reliable high-pressure sealing mechanism. The PI assembly is comprised of an upper junk ring guide, the pressure-intensified (PI) seal assembly, and lower ACME threaded lock ring to hold the packoff in the bottom of the tubing head. The PI design addresses some rather complex problems associated with oilfield elastomer seal designs, including explosive decompression, extrusion at high pressures/temperatures, and seal shrinkage/poor response at low temperatures. The PI seal uses the casing annulus pressure to generate a higher pressure in the elastomer seal, which eliminates the diffusion of gas into the elastomer. This pressure intensification is generated by a movable “T” ring which creates an unbalanced pressure area across the elastomer seal. This design is coupled with FMC’s proprietary seal formulation, which also has improved gas permeation as well as excellent oilfield fluid resistance. The T-ring design also allows the elastomer to self-compensate for seal stress fluctuations caused by thermal cycling. The movement of the T-ring automatically controls excessive seal stresses caused by elastomer expansion. At very low temperatures, the phenomenon of seal stress relaxation caused by elastomer shrinkage is again automatically compensated for by annulus pressure applied to the unbalanced area T-ring. Seal failure due to extrusion is addressed by the use of automatic “ramping” antiextrusion rings made from thermoplastic material. The antiextrusion rings are located at all four corners of the seal. These rings compensate for the extrusion gaps caused by API casing tolerances and manufacturing head tolerances. The PI seal is rated to 15,000 psi working pressure and was developed for use as a lower casing or tubing spool packoff where long-term reliable sealing in hostile environments is required.

M etal Seals SBMS Seals FMC Energy Systems’ straight-bore metal seal (SBMS) is energized by interference between the designated primary sealing surface and the metal seal’s contact area with that sealing surface. The SBMS is a nonintegral double-ended seal sleeve manufactured from high-strength, low-alloy steel or corrosion-resistant alloy. The seal can be installed separately and can be easily replaced. The seal design is based on an interference fit with pressure-intensified sealing. As the tubing head bonnet is nippled up, the seal lip (“bump”) engages an entry ramp in the seal bore, radially deflecting the seal lip inward, creating the contact stress required to effect a seal. In the fully installed position, the seal lips engage a straight bore above the entry ramp (see illustration). The SBMS maintains sufficient contact-sealing stress even at very low pressure. As working pressure increases, contact-sealing stresses increase, making it seal even tighter. The SBMS qualification tests were conducted with low pressure and high pressure, the fire test pass (API RP-6F “Improved”) of 2,000°F flame temperatures and 1,200°F internal seal temperature with zero leakage.
SBMS-II Seals The SBMS-II has “bumps” on the inside diameter and the outside diameter. Each seal lip engages its entry ramp, creating the sealing contact stress with the sealing diameter. The SBMS-II is used mainly as a production casing metal seal on either extended-neck mandrel-casing hangers or directly against the casing stub when slip hangers are used. When employed to seal against a casing stub, it is required to machine the casing stub after the casing is hung off. However, it requires only approximately 1 1/4˝ of the casing stub. The operation can be executed with a portable pneumatic tool. The SBMS-II is normally used on production casing where extreme temperature fluctuations are anticipated or in critical-service applications. When used against slip-suspended casing, FMC Energy Systems provides an ACME threaded casing holddown nut to minimize upward thermal expansion of the casing and act as a bit guide to protect the SBMS-II seal when running tubing or conditioning the hole. The SBMS-II seal has been used in sizes up to 20˝. Various applications of the SBMS-II design include valve stem back-seat seals, valve seat body seals and tubing hanger annular packoffs.
RCMS Seals The most recent addition to the family of metal seals is the rough-casing metal seal (RCMS). This seal design does not require special complex field machining of the casing stub; is compatible with a wide range of temperatures and corrosive environments; does not require special installation tools and is simple to install; is NACE compatible; is compatible with casing spool and tubing spool strength; and is compatible with casing string strength properties.
XEMS Seals FMC Energy Systems’ externally energized metal seal (XEMS) is used in Unihead ® wellhead systems for special mandrel casing hanger and tubing hanger applications. The externally energized seal requires mechanical force to effect a seal. The XEMS seal can be run through the BOP stack and is energized by lockdown screws or by an internal lockdown ring and running tool.

Metal-to-Metal High-Performance Seals The metal-to-metal high-performance (M2M HP) Annulus Seal Assembly seals the annular space between the Unihead and the UWD-15 Casing Hangers. The seal is preloaded at installation, giving outstanding sealing performance even at low pressures. Two seal bumps on the OD of the M2M HP seal assembly seal against a recessed groove in the ID of the Unihead. Three radiused seal bumps on the tapered ID of the M2M HP seal assembly seal against the mating tapered surface on the OD of the casing Hhanger. The seal element material is a corrosion-resistant alloy, rendering the seal assembly fit for use in carbon dioxide environments. All mating equipment is overlaid with a corrosion-resistant alloy. The seal bumps plastically deform during installation, filling scratches that may be present on the sealing surfaces. The M2M HP seal assembly OD locates and aligns within the bore of the Unihead during installation and centralizes the M2M HP seal assembly. The OD also protects the two seal bumps on the seal assembly OD from damage during installation. A square shoulder in the bore of the locking mandrel sits on top of the casing hanger. The M2M HP seal assembly is positioned in the Unihead so that the seal elements align with an undercut in the Unihead bore. This undercut area minimizes scratching or scuffing of the seal surfaces which can occur during drilling operations. When the energizing mandrel is operated, locking segments engage with a groove on the ID of the Unihead. A lock ring in the ID of the M2M seal assembly engages with a groove on the OD of the UW-D15 Casing Hangers. The M2M HP seal assembly bottom surface protects the seal by having a larger diameter that shields the retracted sealing elements during running. The M2M HP seal element is retained on the seal assembly with a retainer strip. This retainer strip is held captive and provides uniform support during seal retrieval. The M2M HP Annulus Seal Assembly is designed to prevent premature energization as the assembly is run downhole. It is rated for 15,000 psi, H2S service and 250oF service. They were successfully tested to 350oF.

Ca p a b i l i t y
wellhead is as good as its valves and seals, and
performance is about seal performance. Higher pressures, well-treatment chemicals, longer frac times and other critical-service conditions place emphasis on seal integrity. If a seal failed, the budget can be severely impacted. Our customers demand the most reliable seals technology can deliver, and our industry has set new standards for seal performance. Conventional O-ring seals no longer meet application demands and industry standards. In order to maintain complete control over the quality and performance of our elastomer seals, FMC Energy Systems has made a substantial investment in an Elastomer Laboratory dedicated to the development of new and improved elastomer seal materials and designs. Field-proven designs developed by FMC Energy Systems include FS-Seals, S-Seals, and Compression Packings with Wire Mesh. At the heart of these premium seal designs are proprietary elastomer compounds formulated to provide the best combination of mechanical properties and chemical resistance to oilfield environments. Molding of FMC Energy Systems’ seal designs using these proprietary compounds is performed at our Nonmetallic Production Facility, located in Houston, Texas. Our experience has demonstrated that in-house elastomer seal manufacture and optimized compounds provide the most reliable combination of mechanical and chemical properties in a premium elastomer seal. This is in contrast to much of the oilfield industry which outsources seal manufacturing. New seal designs demanding new, improved compounds, new molding techniques and testing processes are developed in our Elastomer manufacturing and testing facilities. This assures that FMC Energy Systems brand elastomer seals are not only state-of-the-art design and materials, but rigorously tested for the complete range of customer applications and environmental operating conditions.

OUR UNIQUE RECRUITING PROCESS.
OUR RIGOROUS TRAINING PROGRAM.
While most of the industry tends to recruit service technicians from experienced rig crews, we have followed a different path by recruiting directly from vocational schools and the military services. Technician candidates recruited from these two major sources of talent are already comfortable with formal training courses, have a disciplined approach to following procedures and have great attitudes: they are proud of their company, their skills and their commitment to safety and enjoy helping customers by providing superior service.
Before joining our service team as a fullfledged FMC wellhead technician, every recruit must complete a comprehensive 26-week training program. The curriculum includes classroom study in drilling technology and FMC Surface Wellhead products, hands-on lab and field instruction, as well as a rotation through many functional areas of the business. Above all, our service trainees have the FMC Surface Wellhead safety culture ingrained into every aspect of their thinking, planning and job performance. Before graduating, each apprentice must pass a written competency examination.

Gate Valve Lubrication Ser vices Regular lubrication and maintenance of gate valves can substantially prolong the life of your wellhead system. An ongoing program of valve lubrication is simply good business, as it can reduce the frequency and cost of repairs and well shutdowns. Our technicians flush treating fluids, lubricate bearings and fill the valve body with grease for a single well (for instance, after the equipment has been exposed to corrosive chemicals) or on a routine basis as part of a total field lubrication program. On your valve lubrication maintenance calls, our highly trained and experienced technicians follow a strict schedule of procedures step-by-step to assure thoroughness and uniform service throughout the life cycle of the equipment. They are also guided by detailed reports (including photographs and schematics) that document the size, working pressure, serial numbers and manufacture of each piece of equipment on each wellhead.

Pre-Workover Inspection S e r v i c e A well workover is no time to discover problems with the wellhead. Your FMC Surface Wellhead technicians can help prevent costly workover rig and crew downtime by identifying and documenting the installed equipment and verifying the proper functioning of all wellhead components before the rig arrives. This inspection includes tests for pressure leaks, valve inspection to assure proper functioning, prepping the bolts for fast and easy removal and any necessary repairs. Our technicians also provide test results and documentation for each wellhead as the units are scheduled for workover or moving.

Lubricator installs VR plugs in casing head, casing spool or tubing head side outlets so gate valves can be isolated from pressure for removal or repair. Lubricator mounts on the gate valve outlet flange. With the lubricator holding the pressure, the gate valve can be opened, allowing the VR plug to pass through the valve and be threaded into the head or spool outlet. All studded and flanged outlets on FMC Energy Systems casing heads, casing spools and tubing heads are threaded to accept VR plugs. VR adapters are available for threaded outlets. For outlet working pressures of 15,000 psi, straight-thread, metal-tometal seal VR plugs are standard. For lower working pressures, tapered-thread VR plugs are standard.

Similar to the back-pressure valve, but with the seat and stinger arranged to hold pressure from above, sealing the tubing bore against tree test pressure. Test plug installs exactly the same way as the back-pressure valve. Since the plug will not hold pressure from below, well pressure must be isolated from the tree using a downhole plug or SCSSV.

Latches into mating groove in TCSeries tubing hangers or couplings to seal the well bore while the blowout preventers are removed and the tree is installed. Also used to temporarily isolate the tree from well pressure for repairs without killing the well. Installed by hand or by hydraulic lubricator. Shear pin release provides positive setting indication. Seals in hanger or coupling where strength is maximum and dimensional tolerances are controlled, not in tubing. Valve cannot accidentally pass into tubing. Internal stinger makes it easy to check well bore for pressure, or to equalize pressure across the valve.
