Selecting a Wellhead System

Major Considerations for Casing Hanger Selection •

•

•

•

•

•

The first step in determining which Cameron wellhead system is best for your application is to determine the casing hanger style to be used. Each hanger profile is unique and is generally compatible with only a limited number of casing head/spool bowls. Cameron has a complete line of slip-type casing hangers divided into two segments, SB and IC, each serving different applications.

Casing Hangers for S Casing Head Housings and Spools

Cameron S Casing Head Spools and Housings accept all three hangers in the SB hanger family. SB hangers can be lowered through the BOP as soon as the cement plug hits bottom. Once in place, they support the entire casing weight and seal the annulus. Mandrel style casing hangers can also be supplied. The unique slip design of the SB family of hangers achieves controlled friction when precision-machined slips with sharp inner teeth securely bite casing, while dull outer teeth on the back side contact the slip bowl. Because these hangers are installed in the double 45° shoulder housing design, the mechanical load is completely separated from the hydraulic load. This allows the assembly to hold full test pressure while varying the slip load from zero to full joint strength without changing deflection of casing in the pressured zone. SB-3 Casing Hanger The SB-3 Casing Hanger is a wrap-around slip and seal assembly designed for 5000 psi WP service. It is rated for a hang-off capacity of 80% of pipe body yield. Like the other slips in the SB family, it requires a load of only 15,000 lb to set the seal. In addition, the seal can be re-energized by tightening the cap screws. The seal can be replaced with the full rated load on the hanger. • SB-5 Casing Hanger The SB-5 Casing Hanger is a wrap-around slip and seal assembly designed for 10,000 and 15,000 psi WP service. It is rated for a hang-off capacity of 80% of pipe body yield. Like the other slips in the SB family, it requires a load of only 15,000 lb to set the seal. In addition, the seal can be

re-energized by tightening the cap screws. The seal can be replaced with the full rated load on the hanger. The SB-5 Casing Hanger can only be used in the Type S spool (i.e. cannot be used with spools supplied with lock screws). • SB-6 Casing Hanger The SB-6 Casing Hanger is a wrap-around slip and seal assembly designed for 5000 psi WP service. It is rated for a hang-off capacity of 70% of pipe body yield. Like the other slips in the SB family, it requires a load of only 15,000 lb to set the seal. In addition, the seal can be re-energized by tightening the cap screws. The seal can be replaced with the full rated load on the hanger.

IC-2 Casing Head Housings and Spools

The IC-2 Casing Head Housing seals off the surface casing and provides a landing bowl for the next casing string as well as an attachment for the BOP stack. The IC-2 Casing Spool seals off the surface casing string and its landing bowl provides support for the next casing string.

Casing Hangers for IC-2 Casing Head Housings and Spools

Cameron IC-2 Casing Head Spools and Housings accept all three hangers in the IC hanger family. IC hangers offer a selection of manually energized seals or weight set seals, depending upon application requirements. They also offer a choice of one-piece and two-piece design so that use of IC-2 equipment for different applications can be varied by slip selection alone. IC Hangers land on the single 45° shoulder in IC-2 bowls. Mandrel style casing hangers can also be supplied. •

IC-1 Casing Hanger The IC-1 Casing Hanger is an independent slip and seal assembly. The slip assembly is latched around the casing and lowered into the casing head. The seal assembly is installed over the casing after it is cut-off. Pressure applied to the top of the seal assembly is transferred to the casing head, not the slips. This hanger can only be used in the IC-2 bowl profile (i.e. cannot be used with spools provided with lock screws).

•

IC-1-P Casing Hanger The IC-1-P Casing Hanger is a one-piece, non-automatic, wrap-around hanger which is ideal for use where casing weight is insufficient to energize the hanger seal. The seal is

energized using cap screws and can be replaced with rated load on the hanger. This hanger can only be used in the IC-2 bowl profile (i.e. cannot be used with spools provided with lock screws).

•

IC-2 Casing Hanger The IC-2 Casing Hanger is a wrap-around hanger with an

annulus seal which is energized by casing weight. The weight to energize the seal varies with the casing and slip size. The hanger uses a heavy duty latch and hinge design which creates a reliable, strong and stable hanger structure after closing. The hinge mechanism enables the hanger halves to pivot out of the way during “wrap-around.” Tapered “rough backs” allow a quick, secure bite of the casing, restrict continued downward movement, and prevent collapse of the casing. A guide ring maintains slip alignment during installation and operation.

Cameron Tubing Spools and Hangers

Cameron offers a wide variety of tubing spools and hangers for all types of completions: single, dual, high pressure, and severe service. The standard Cameron C bowl design is utilized in both the C and CD-2 Tubing Spool designs. Use of this profile as standard allows Cameron to offer the widest possible array of tubing hanger choices while minimizing tubing spool requirements. Of the tubing hangers offered all but one, the MTBS (designed for critical service applications), fit the C profile. Like our wellhead components, all Cameron completion components meet or exceed API 6A specifications. Included in these products is a complete line of completion equipment and Christmas trees to suit all tubing programs for working pressures up to 30,000 psi. Equipment for surface applications range from low pressure, conventional equipment to systems for severe service and geothermal applications. For completion equipment not covered in this brochure, contact your Cameron representative.

Selecting a Completion System The first step in determining which Cameron completion system is best for your application is to determine the tubing hanger style to be used. Each hanger profile is unique and is generally compatible with only a limited number of casing head/spool bowls.

Tubing Hangers for Single Completions

HT and HT-2 Tubing Hanger Assemblies The HT and HT-2 Tubing Hanger Assemblies are all single completion hanger assemblies for use in either the C Tubing Spool or the CD-2 Tubing Spool. Both designs are made up of a coupling, adapter and Type C wrap-around style casing hanger. The HT-2 also includes a suspension nut which allows installation without rotating the Christmas tree. The HT-2 is preferred for stainless steel hanger and adapter applications due to decreased risk of galling. Both assemblies are rated up to 10,000 psi WP and are simple and quick to install without special running tools. •

HT and HT-2 Couplings Both designs include coarse ACME threads which make up easily with minimum risk of damage. Self-energizing seals isolate threads from well fluids, allowing testing of flange ring gasket.

HT and HT-2 Adapters Both adapter top and bottom connections are normally configured with a flanged bottom and studded top. The designs provides a test port for verification of adapter flange connection and coupling seal integrity. • HT-2 Suspension Nut The HT-2 Suspension nut is made of a high-strength, lowalloy, gall resistant material. A coupling seal isolates the nut from flow pressure, preventing corrosion. • C Tubing Hanger The C Tubing Hanger is a wrap-around slip and seal assembly. The annulus seal is energized by tubing weight or tiedown screws and controls pressure in the casing annulus during installation of the Christmas tree. •

Tubing Spools and Hangers for Critical Service Applications

MTBS Tubing Spool and MTBS Tubing Hanger The MTBS Tubing Spool is a single completion, metal-to-metal sealing spool for critical service applications to 20,000 psi WP. Features include: •

Metal-to-Metal Sealing The MTBS Tubing Spool and MTBS Tubing Hanger provide complete metal-to-metal sealing. The annulus seal is radially squeezed into contact with parallel cylindrical sealing surfaces in the spool bore. The annulus and neck seals are simultaneously pressure-energized with flange makeup. The annulus seal is retrieved when the hanger is pulled from mating bowl preparation.

•

MTBS Tubing Hanger The MTBS Tubing Hanger is made of high alloy materials to withstand corrosive and high temperature environments. The extended neck ensures positive alignment for the seal during installation. The hanger is reusable and the metal seals are replaceable. Bowl Design A straight bore bowl design provides a large through bore and allows a 7-1/16” flange to be used over a 7-5/8” casing string. Type N Lock Screws Reliable N Lock Screws feature packing installed in front of the threads. This prevents contamination of threads by wellbore fluids and helps eliminate build-up of solids behind the screw. See page 21 for more information on N Lock Screws. Side Outlets MTBS Spools are available with studded outlets threaded for valve removal plugs. Secondary Seals MTBS Tubing Spools are available with Single and Double P, Single and Double T, and NX Bushing and CANH secondary seals. See page 20 for more information. Test and Injection Ports All test ports are metal sealing and are designed to allow venting. Injection ports include buried check valves. See page 21 for more information.

Casing Head Housing Bottom Connection Options •

SlipLock™ Casing Connection System The SlipLock Casing Connection System is a simple slip mechanism which reduces installation time because welding is eliminated. Sealing is achieved with elastomeric P Seals. The SlipLock system can be used for working pressures up to 10,000 psi and is reusable for exploration wells.

•

CAMFORGE™ Casing Connection System The CAMFORGE Casing Connection System requires no welding and no premachining of casing. The casing is mechanically cut so that existing production does not have to be shut in. The connection is made using hydraulic pressure to expand the surface casing and housing. The system establishes a pressure-tight, metal sealing connection suitable for working pressures up to 10,000 psi. The CAMFORGE system minimizes rig time and duration of open hole time without BOP protection. Annulus hydro-testing simulates working conditions prior to BOP nipple up.

•

Slip-On Weld Slip on weld bottom connections are standard with O-rings for both S and IC-2 casing heads with 10-3/4” or smaller casing preparations. For larger casing sizes, the O-ring seal option is not available. If utilized, the O-ring seal requires only one external weld. Slip-on weld connections include a 1/2” line pipe test port to validate the integrity of both the weld and the O-ring seals.

•

Casing Box Thread Casing threads are intended for use where threaded

connections are specified for casing heads. In this case, the lower connection outside diameter is standardized where possible to allow use of raw material for either S or IC-2 style heads.

Secondary Seals Cameron offers a wide range of secondary seals for use in casing and tubing spools. These secondary seals are installed in the bottom of spools with corresponding preps. Single and Double P Seals The Single and Double P Seals are ideal for use as crossovers where moderately severe service is expected. Each P Seal consists of a large elastomer seal with separate anti-extrusion rings. Both Single and Double P Seals are sized to accommodate the tolerance range of casing and may be used on machined hanger necks. Double P Seals can be tested with pressure applied between the seals. • Single and Double T Seals Single and Double T Seals are interference-fit, elastomeric seals for use with casing sizes 10-3/4” and smaller. They are ideal for use as crossovers where moderately severe service is expected. Both Single and Double T Seals are sized to accommodate the tolerance range of casing and may be used on machined hanger necks. Double T Seals can be tested with pressure applied between the seals. •

NX Bushing NX Bushings accommodate variations in casing programs. The NX Bushing utilizes a P seal and is retained in the spool with a retainer wire. Either integral or separate bit guides can be provided. • CANH™ Seal The CANH Seal is a metal-to-metal crossover seal which has been designed for severe service and corrosive environments. This seal can be installed and tested on standard “rough” pipe with minimal cleanup. Field machining is not required in normal applications. Its simple, flange-energized design achieves a gas-tight seal. Sealing occurs at four nibs machined into the inner and outer seal rings. Note: The CANH Seal is not recommended for use with IC-2 slips. Spools equipped with CANH Seal bottoms require special CANH Seal support rings when making up to an IC-2 Spool. •
