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.

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-
ments associated with well flow. Its flexible neck main-
tains the metal seal despite thermal or pressure cycling.
T-CL TUBING HANGER The T-CL Tubing Hanger with-stands stress of high pressure and corrosive or erosive
elements associated with well flow. A control line exit
block is available in either a bull plug style or block nee-
dle valve style.
C-SRL-CL TUBING HANGER The C-SRL-CL Tubing Hanger
incorporates a pressure energized SRL neck seal, which
accommodates vertical movement in the tubing hanger
during BOP testing. A control line exit block is available

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.
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.

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.
