TechnipFMC | Our drilling technology
Experience faster time to production, lower operating costs
and reduced non-productive time through field-proven
standardised drilling systems
Field proven from cost effective conventional to high
performance Uniheads®
TechnipFMC’s structured and comprehensive portfolio
delivers a broad set of standardised drilling products
with cost and time efficient solutions, delivering the
perfect balance of functionality and reliability for all
our customers’ well applications.
The technology is fully validated through rigorous
test protocols that align with API standards, and when
required exceed those limits providing a greater level
of reliability for customer operations coupled with
many years of field use, this ensures our technology
meets our customer’s requirements of reliability
and quality.
We continually invest in research and development
to meet the evolving needs of our industry. All
innovations are subjected to exhaustive laboratory
and field tests to ensure their reliability and integrity
before they are released to the marketplace.
Safety and reliability
TechnipFMC’s standardised equipment and renowned
sealing technology help eliminate the threat of
working under suspended loads, minimise BOP
manipulation, reduce installation risks and improve
safety throughout the drilling process.
Our ability to address complex project challenges
comes from a strong track record of project
management expertise. We deliver projects on time,
reducing installation risks and never compromising on
quality or safety.
Shorter time to production
Non-productive time (NPT) can have a major impact
on well economics. Our drilling technology mitigates
risks through our robust design verification and
validation program, optimising well integrity and
minimising NPT and the risks associated with the
drilling and equipment installation process.
TechnipFMC’s stocking programs ensure our standard
components and sub-assembly products are
available and ready to be installed to help boost your
productivity and accelerate time to first oil.
We deliver top-rated field execution services 24/7,
with trained, competent technicians to make sure the
job is done right and safely.

TechnipFMC | Sealing technology
Sealing technology
The foundation of any wellhead system is the sealing
technology and its integrity over the productive life of the well
When enhanced sealing performance is needed, we offer a wide variety of
metal-to-metal seal technology:
`
Industry leading Rough Casing Metal Seal (RCMS) for gas tight sealing on
rough casing. High and low tolerances seal elements accommodating the
full API tolerance range.
`
Externally Energised Metal Seal (XEMS) for annular sealing on casing
and tubing hangers. Activated via the External Thread (ET) lock screws.
`
Straight Bore Metal Seal (SBMS) for gas tight sealing between the tubing
hanger neck and Christmas tree.
`
Fire testing on metal-to-metal seals.
The conventional product family provides a broad range of non-metallic
seal technologies:
`
S and FS Seals for machined and rough casing designed in-house using
proprietary elastomer compounds (NBR, HNBR and FKM)
`
Slab packing for our slip hanger portfolio
`
Pressure Intensified packoff bushing for working pressures up to
15,000 psi on rough casing
`
Dovetail, L-Packing and compression packing for installation tooling
Metallic and non-metallic seals have been qualified
in accordance with API 6A PR2F.

Externally Energised Metal Seal (XEMS)
TechnipFMC has solid track record of investing in the development of new seal technologies both metallic and non-metallic to
handle all well conditions from low pressure oil wells to high pressure and high temperature gas wells. Our seal technologies
are reliable, robust and practical, delivering trouble-free seal integrity throughout the life of the well. Our seal capabilities
cover 2,000 psi through 20,000 psi and temperatures from -75°F to 400°F.
Conventional wellhead
solutions for maximum
interchangeability
Selecting a conventional wellhead product
provides the operator a solution that has the
greatest flexibility and interchangeability,
lowest CAPEX and highest convenience. With
conventional wellheads, complexities are
reduced and modular formats fit all casing
programs.
Our standardised approach has provided an
agile and global supply chain to deliver our
wellhead products in the shortest possible time
frame. Stocking programs allow our drilling
products to be held in inventory, providing our
global customers maximum flexibility for their
drilling programs.
Our conventional wellhead products comprising
heads, spools, hangers and completion
equipment has gained a solid reputation of
delivering customer success for more than
80 years. We collaborate with our customers
to understand their challenges and provide
practical and proven solutions for their drilling
and production operations. We deliver simple,
robust and reliable systems for both onshore

Casing heads and casing spools
Extensive range
TechnipFMC offers an wide range of C-22 and C-29 casing heads and spools covering multiple flange sizes
from 7 1/16 to 30-inches. The maximum rated working pressure ranges from 2,000 psi to 20,000 psi. The
equipment is rated for temperatures from -75° F to 350° F.
The casing heads are configured with a common lower profile for the base plate and are available with
studded side outlets or line pipe outlets. The lower connection can be configured with a variety of
profiles including slip-on-weld, threaded or Slip Loc. For hanger retention, the heads can be configured
with external thread (ET) lock screws.

Casing head
For low to medium casing loads, the heads can be
configured with the C-22 bowl profile accepting all C-21 and
C-22 style slip hangers.
For heavier or more extreme casing string loads, the heads
can be equipped with a C-29 bowl allowing all slip hanger
options to be used.
Installation is quick and straightforward using either
individual running and retrieving tools or combination tools
that also allow BOP testing.
The C-22 and C-29 style heads and spools are practical and
offer our customers a robust and economical means of
drilling wells onshore or offshore.

The C-22 Elastomer Groove (EG) profile eliminates the
need to lockdown screws to retain the bowl protector.
This profile is also common for the C-22 casing heads.
The bottom preparation accepts a variety of secondary
elastomer or metal to metal seals to achieve annular
seal integrity.

TechnipFMC | Casing hangers
Casing hangers
Standard
Casing suspension is achieved with our standard C-21,
C-21F, C-22 and C-29 slip hangers. These hanger options
cover a wide range of applications:
`
Casing suspension with individual seal ring
`
Automatic weight set
`
Non-automatic requiring manual energisation of the
annular seal
The C-22 and C-29 style hangers use a split packing
manufactured from nitrile or HNBR material. These
materials cover both sweet and sour service applications
(AA thru HH). Our casing hangers meet API 6A’s PR1 or
PR2 requirements.

C-229 casing hanger
C-100 and C-200 series
For more extreme well conditions where PR2F
qualification is required, we have developed the C-100
and C-200 range of slip hangers.
The C-121, C-122 and C-129 are qualified to 80 percent of
pipe body yield to API temperature class U.
The C-200 series of slip hanger is designed for extreme
casing loads in excess of 1M pounds and temperatures
of 300° F. Extensive qualification testing has validated
these heavy duty hangers for a variety of casing sizes in
accordance with API 6A PR2 Appendix F.
