S AND IC WELLHEAD SYSTEMS

Camerons two conventional wellhead systemsthe

S system and the IC systemare both compatible with

most Cameron tubing spool and hanger configurations.

The S Conventional Wellhead System is the indus-

trys highest capacity conventional spool-type wellhead.

Designed for use with all well depths and all types of

completions, the S system may be used in place of the

IC Wellhead for all applications.

For a wide range of applications, the IC Wellhead

System offers a cost-effective, reliable alternative

designed for less intense conditions.

SELECTING A WELLHEAD SYSTEM

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 heads and spool bowls.

The four components to consider when selecting a

casing hanger are the temperature range, hang-off

capacity, working pressure and the method used to set

the annulus seal. Please refer to the charts on this page

as you select the casing hanger to suit your needs.

It also provides an attachment for the BOP stack.

CASING HEAD HOUSINGBOTTOM CONNECTION OPTIONS

SLIPLOCK CASING CONNECTION SYSTEM The SlipLock

Casing Connection System reduces installation time by

eliminating the need for welding. The system achieves

the necessary seal using elastomeric T Seals or plastic

injection-energized P Seals.

The SlipLock system performs in working pressures

up to 10,000 psi. Because it is reusable, it is an appropri-

ate choice for exploration wells.

CAMFORGE CASING CONNECTION SYSTEM The

CAMFORGE Casing Connection System requires no

welding and no pre-machining of the casing. Because

the casing is mechanically cut, 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-

CASING HANGERS FOR IC-2 CASING HEADHOUSINGS AND SPOOLS

Cameron IC-2 Casing Head Housings and Spools accept

all three hangers in the IC hanger family. Cameron offers

a selection of IC hangers using manually energized seals

or weight-set seals, depending upon application require-

ments. IC hangers are available in one-piece and two-

piece designs, so 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 also can 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 to the

slips. The IC-1 hanger can be used only in the IC-2 bowl

profile; it 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 that is

ideal for use when casing weight is insufficient to ener-

gize the hanger

seal. The seal is

energized using

cap screws and can be

replaced with rated

load on the hanger.

This hanger can be used only in the IC-2 bowl profile; it

cannot be used with spools provided with lock screws.

IC-2 CASING HANGER The IC-2 Casing Hanger is awrap-around hanger with an annulus seal. This hanger

is energized by casing weight, which varies with the

casing and slip

size. The hanger

uses a heavy-duty

latch and hinge design

that 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.

TUBING SPOOLS AND HANGERS

Camerons wide variety of tubing spools and hangers

suits all types of completions single, dual, high

pressure and severe service.

Cameron uses a standard C profile for tubing spools.

Use of this profile allows Cameron to offer the widest

possible array of tubing hanger choices while minimiz-

ing 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 comple-

tion components meet or exceed API 6A specifications.

These products include a full line of completion equip-

ment and Christmas trees to suit all tubing programs for

working pressures up to 30,000 psi. From low-pressure

conventional equipment to systems for severe service

and geothermal applications, Cameron can supply the

completion components.

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 (see chart on page 13). Each hanger

profile is unique and is generally compatible with only

a limited number of casing head and spool bowls.

TUBING SPOOLS FOR SINGLE COMPLETIONS

Camerons C Tubing Spool is the standard spool for

single completions in 7-1/16 and 9 nominal top

flange sizes. The IC-2-L Spool is used for 11 and13-5/8 nominal tubing spools. Features include:

BOWL DESIGN A straight bore with a single 45

shoulder design provides support for the tubing load

and reduces the risk of bowl damage from drill stem

rotation. This design minimizes hoop load on the spool

while maintaining high hanging capacity.

TUBING HANGER COMPATIBILITY The tubing spool

accommodates a wide variety of tubing hangers for single

completions including HT, HT-2, C-SRL-CL, T, T-CL and CXS

designs. See the following page for more information.

TYPE N LOCK SCREWS Reliable Type N Lock Screws fea-

ture packing installed in front of the threads to prevent

any contamination of threads by well-bore fluids and to

help eliminate build-up of

solids behind the screw.

See page 18 for more infor-

mation on Type N Lock

Screws.

SIDE OUTLETS Line-pipe

threaded and studded out-

lets are available.

Studded outlets are

threaded for valve

removal plugs.

SECONDARY SEALS C Tubing Spools are available with

Single and Double P, Single and Double T, and NX

Bushing and CANH secondary seals. See pages 8-9 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 18 for more

information.

TUBING HANGERS FOR SINGLE COMPLETIONS

The HT and HT-2 Tubing Hanger Assemblies are 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, an adapter and a Type C wrap-

C Tubing Spool

around style casing hanger. The HT-2 is the preferred

design for stainless steel applications. It incorporates a

suspension nut that allows installation without rotating

the Christmas tree. Both assemblies are rated up to10,000 psi WP and are easy 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 the flange ring

gasket.

HT AND HT-2 ADAPTERS Both adapter top and bottom

connections are normally configured with a flanged

bottom and studded top, providing a test port for veri-

fication of the adapter flange connection and coupling

seal integrity.

HT-2 SUSPENSION NUT The HT-2 Suspension Nut is

made of a high-strength, low-alloy, gall-resistant mate-

rial. 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 ener-

gized by tubing weight or tie-down screws and controls

pressure in the casing annulus during installation of the

Christmas tree.

The T, T-CL, C-SRL-CL and CXS Tubing Hangers are single

completion, mandrel-type hangers for use in either the

C Tubing Spool or the CD-2 Tubing Spool.

T TUBING HANGER The T Tubing Hanger withstands

the stress of high pressure and corrosive or erosive ele-

TUBING HANGERS FOR DUAL COMPLETIONS

Camerons dual completion tubing hangers include

three designs: the CD-2N Tubing Hanger, CD-T Tubing

Hanger and CD-T-CL Tubing Hanger. These hangers

used with the CD-2 Tubing Spoolare split dual man-

drel style hangers that can be run and pulled independ-

ently. The alignment slots are located below the load

shoulder to protect the alignment pins from tubing

weight, allowing maximum load capacity.

TUBING SPOOLS FOR DUAL COMPLETIONS

The CD-2 Tubing Spool features the same bowl as the

C Tubing Spool but incorporates alignment pins for

dual completions. The CD-2 also can be used for single

completions by retracting

the alignment pins.

Features include:

BOWL DESIGN A straight

bore with a single 45 shoulder

design provides support for the

tubing load and reduces

the risk of bowl damage

due to drill stem rotation.

This design minimizes hoop load on the spool while

maintaining high hanging capacity.

TUBING HANGER COMPATIBILITY The tubing spools

accommodate a wide variety of tubing hangers for sin-

gle completions including HT, HT-2, C-SRL-CL, T, T-CL

and CXS designs for single completions and the CD-2N,

CD-T and CD-T-CL hangers for dual completions.

TYPE N LOCK SCREWS Reliable Type N Lock Screws fea-

ture packing installed in front of the threads to prevent

contamination of the threads by wellbore fluids and to

help eliminate build-up of solids behind the screw. See

page 18 for more information.

ALIGNMENT PINS Alignment pins for dual completions

are located below the load shoulder to avoid test plug

interference and to provide alignment without reduc-

ing load shoulder capacity. CD-2NTubing Hanger

TUBING SPOOLS FORCRITICAL SERVICE COMPLETIONS

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 squeezed to contact

parallel cylindrical sealingsurfaces in the spool bore.

The annulus seal is set using tubing weight with addi-

tional pressure load when required. The neck seal is

energized by flange make up.

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 all 7casing strings.

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

18 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 pages 8-9 for

more information.

LOCK SCREWS, TEST PORTS AND INJECTION PORTS

N LOCK SCREWS All Cameron spools and housings use

N Lock Screws. These field-replaceable screws contain

packing in front of the threads to prevent contamina-

tion by well bore fluids and build up of solids behind

the screws, which could prevent proper retraction.

An external oil seal protects threads from atmospheric

corrosion.

TEST PORTS All test ports used in Cameron convention-

al wellhead equipment meet the standard for API 6A

Type II metal seal design for safety and reliability.

These ports can be vented safely and are usable with

all pressure ratings.

INJECTION PORTS For casing and tubing spools that

require injection of sealant to energize or re-energize

the secondary seal, two styles of fittings are available.

Each style has a buried ball check (without spring). For

applications 10,000 psi WP and below, the port features

a simple plug with a 1 NPT thread. For working pres-

sures above 10,000 psi WP, the port incorporates a two-

piece plug with a pressure vent.
