Drill-Through Wellhead System
Drilling

The drill-through wellhead system maximizes efficiency by streamlining
drilling operations. Well control is achieved with one BOP rig-up, resulting
in safer drilling activities and providing significant time savings that reduce
rig costs. Mandrel hangers eliminate the need to set slips and perform
rough and final casing cut. Rig-up and rig-down is faster, fewer personnel
are required during the process, and the period of time personnel need to
work under suspended loads in confined area is minimized. Additionally,
hot work during the drilling phase is not required.

MN-DS Multibowl Nested-Diverter
Snap-Ring Wellhead System
Drilling

The MN-DS* multibowl nested-diverter snap-ring wellhead system
is specifically designed for shale plays. Its compact design is configurable
to eliminate intermediate casing strings and enables the wellhead system
to be run through a diverter riser, saving time and cost. The system
enhances safety and well integrity because it uses internal mechanical
locking rings rather than external locking mechanisms such as lockscrews,
and it has no unnecessary body penetrations. Eliminating lockscrews—
which are widely used in conventional wellheads—significantly reduces
potential leak paths and facilitates any wellhead intervention under the
BOPs that may be required during drilling.

SOLIDrill Modular Compact Wellhead System
Correctly installing the wellhead is crucial to drilling and workover operation
success. But most conventional installations involve landing tubing hangers on top
of the casing hanger packoff’s flat area, where debris can accumulate. This condition
causes the wellhead to be misaligned, preventing proper installation and resulting
in NPT. For operators conducting drilling and workovers involving complex land or
deepwater wells, these challenges are accentuated.
Such conditions are mitigated with the SOLIDrill* modular compact wellhead system.
Available in either two-or three-stage arrangements with 11-in and 13⅝-in nominal
sizes, the SOLIDrill system has a compact, unitized housing and provides operational
flexibility in a single system. The system is designed to endure extreme operating
conditions, pressures up to 10,000 psi, and severe kickoff well angles up to 60°
kickoff at 80 m while increasing safety and efficiency. Its proprietary design reduces
the possibility of hanger tilt and secures reliable hanger alignment while reducing
wellhead debris.

CAMShale Fracturing Fluid Delivery
and Flowback Service
For operators with challenging unconventional
play economics, where maximizing operational
efficiency while maintaining the technical
integrity of all high-pressure activities is
essential, the CAMShale* fracturing fluid
delivery and flowback service is the answer.
The service provides seamless delivery of
hydraulic fracturing fluid from the pumping
service provider’s missile trailer to the wellbore
and through to flowback. Comprehensive,
integrated service and support from a single
provider helps optimize overall efficiency while
reducing NPT, costs, and the environmental
impact of unconventional completions.
Multiskilled crews minimize wellsite personnel
and reduce logistics demands. The continuity
of trained personnel, innovative equipment,
and rigorous maintenance programs improve
operational integrity and safety.
By removing as much nonproductive preparatory
work from critical-path operations as possible,
the CAMShale service helps you reach first oil
or gas faster and minimize the cost per barrel
of oil equivalent.

Streamlined operations through
technology integration
The service incorporates frac trees—including
composite frac trees, which are shorter
and lighter than the conventional models;
flexible, modular fracture manifolds that
enable control of fluid flow to multiple wells,
eliminating rig-up and rig-down between
stages; flowback equipment and well test
separators tailored to operating conditions and
regulatory requirements; and multiskilled trained
personnel using standard procedures developed
through a proprietary Schlumberger process
improvement methodology.
Technologies and services that bring significant
advantages to the CAMShale service include
■■

Monoline* flanged-connection fracturing fluid
delivery technology, which provides a safer,
faster, cleaner alternative to conventional frac
iron for multiwell and pad operations
composite frac trees, including F-T90*
horizontal frac trees, which are 50% shorter
and 25% lighter compared with conventional
frac trees.

Continuity of ownership and competency
With the CAMShale service, a Cameron crew
is on site from the time fracturing fluid delivery
equipment is installed through the entire
fracturing operation, flowback, and any well
testing. The result is a smooth transition from
completion to production and a single point of
contact for the entire surface completion beyond
the pressure pumping provider. Additionally,
the service assists in contingency planning. For
example, in the event of a screenout, flowback
equipment and a trained crew are already on
site to clean out the wellbore in the shortest
possible time.

Frac Trees
With the advent of large-scale fracturing operations, fracturing equipment has undergone an
evolution in design as the systems have been tasked to cope with an aggressively corrosive and
abrasive service life that is well beyond the original design parameters. Valves used in fracture
stimulation processes have a significantly different life cycle than those used in production.
Cameron frac trees provide a substantial advancement in performance for shale applications by
providing increased durability, flexibility, and operational safety. They have also been specially
manufactured to endure the sustained pressure pumping of erosive fracturing fluids. The value of
these capabilities becomes obvious as operators push lateral lengths and increase fracturing stages
to increase completion and production performance for their shale applications. Our frac trees are
available in conventional and vertical and horizontal composite configurations in sizes up to 7 in
and working pressures up to 15,000 psi.

Frac Trees | 25

Composite Frac Trees
Designed for hydraulic fracturing pressures up to 15,000 psi, the Cameron
composite frac tree houses the master valves, swab valves, and horizontal
wing outlets in a single block body, resulting in a significantly shorter
assembly—25% shorter than a conventional stacked-valve design. The
reduced tree height decreases the bending stress transferred from the goat
head to the tree and wellhead connections below. The system enables
using a second actuated swab valve, increasing flow control while still
maintaining a reasonable height.

F-T90 Horizontal Frac Tree

Compared with conventional frac trees, the F-T90 frac tree’s goat head
is located closer to the wellhead. By giving the tree a lower center of
gravity, the bending moment is reduced, which protects the wellhead
tree interface. The F-T90 frac tree can be operated with pneumatic,
hydraulic, or electric actuation and is available in three systems:
■■

5⅛ in and 10,000 psi

■■

71/16 in and 10,000 psi

■■

Built to minimize the bending moments often induced by fracturing operations, the F-T90
tree has a substantially reduced moment arm between the lower tree connection and the
point of attachment to the fracturing head.

F-T90 Horizontal Frac Tree | 27

Unconventional
Completions

The patented F-T90* horizontal frac tree is the industry’s first horizontal
frac tree and was specifically developed to complement multiwell pad
drilling and completions and simultaneous operations. The F-T90 frac
tree is approximately 50% shorter and 25% lighter compared with
conventional frac trees, resulting in a shorter, more stable, and more
easily anchored tree.

Frac Manifolds
A frac manifold is an arrangement of flow fittings and valves installed
downstream of the fracturing pump output header and upstream of each
frac tree being served. Modular and flexible Cameron frac manifolds can be
assembled in many configurations. Each leg of the manifold can be aligned
vertically, horizontally, or at any angle and will typically have one or two
gate valves.
Time spent waiting while an isolation plug is set, perforating guns are
positioned and fired in the next zone, the wireline and gun carriers are
retrieved, and the lubricator is isolated from the well contributes to costly
underutilization of the fracturing crew and equipment. The Cameron frac
manifold minimizes idle time for resources and enables their continuous
use. Manifold outlets are preconnected to multiple frac tree goat heads,
and the manifold output is directed to alternating wells while isolation
plugs are set and new fracturing zones are perforated.

Cameron gate valves in frac trees and manifolds can reliably flow and control highpressure, high-volume, erosive, corrosive, and sometimes sour fracturing and flowback
fluids for days.

Frac Valves | 29

Unconventional
Completions

Gate valves assembled into frac trees and manifolds are exposed to
continuous service, flowing and controlling high-pressure, high-volume,
abrasive fracturing fluid for long periods of time. The Cameron frac valve
offering consists of the widely recognized and field-proven manual FLS-R
API 6A gate valve with reliable metal-to-metal seals throughout and the
actuated FLS-DA2* API 6A double-acting actuated gate valve designed
for quick and easy field maintenance. The FLS-Frac* API 6A slab-style
gate valve is a high-quality valve designed specifically for fracturing
applications. They are specially fitted with corrosion- and erosion-resistant
trim, CRA inlay in seat pockets and ring grooves for added protection,
zero-chamfer flowbores to mitigate turbulence that is known to increase
erosion, and grease ports for flushing and greasing the valve body cavity.

Monoline Flanged-Connection Fracturing Fluid
Delivery Technology
Monoline flanged-connection fracturing fluid delivery technology presents
a safer, faster, cleaner alternative to conventional frac iron on multiwell
pads, changing the way proppant and fracturing fluid are delivered from
the pump spread to the wellbore. The technology is faster to mobilize and
increases fracturing uptime while requiring fewer technicians on location.
It simplifies the rig-up procedure by arriving on location preassembled;
installation time is reduced by more than 60%.
The technology eliminates the potential to mismatch equipment, simplifies
hookup, eliminates multiple flowlines, and reduces the number of
connections or potential leak paths by up to 75%, thus decreasing HSE
risk (conventional systems have 4–8 lines per well with 8–14 connections
per line).
The single-line technology adheres to API 6A standards and comprises
straight high-pressure pipe segments, 90° elbows, and swivel flanges
that are bolted together. Replacing multiple hammer unions with far
fewer, measurably torqued flanged connections with metal sealing
gaskets promotes a higher level of system integrity, safety, and reliability
and lower NPT. The technology enables the full 3° of freedom needed to
accommodate alignment between the frac tree and frac manifold.

Indirect Heaters

Unconventional
Completions

Heaters are used in almost every phase of oil production and processing.
In gas applications, where lower flowing or ambient temperatures are
present, production challenges exist when a pressure differential is
anticipated. These conditions can lead to the formation of hydrates, which
can cause damage to equipment and lower overall separation efficiency.
In these cases, Cameron recommends the use of an indirect heater to
raise the inlet process temperature and control the pressure drop prior
to separation.

API 6A Gate Valves
Over the course of the last century, numerous gate valve design genres have been
developed for use in the oil and gas industry.
Designs that have commonly been used to control fluid flow through production trees and flowlines
include expanding-, wedge-, and slab-style gate valves.
After a careful review of these existing designs, Cameron engineers have selected the best-suited
features for development and implementation into our API 6A gate valve product line. Our valve line
includes some of the world’s most successful and widely recognized gate valves.

Hydraulic Wireline-Cutting Actuators
The hydraulic wireline-cutting actuator is
used primarily during wireline operations. This
actuator operates as a conventional actuator
to open or close a gate valve during normal
production periods; it also becomes a primary
safety device during wireline operations by
ensuring that the well can still be shut in should
an emergency occur. This is possible because of
the springs, which exert high forces to cut the
wireline cable, braided line, or coiled tubing.
Cameron’s hydraulic wireline-cutting actuators
offer a reliable and robust design that can be
installed in harsh and remote environments.

High-Integrity Pressure Protection System (HIPPS) | 55

Production

When operating in high-pressure environments and production fields,
an overpressure event can cause damage to the environment,
infrastructure, and personnel. Mitigating that risk on production wells
and flowlines is a challenge that can be met with a HIPPS, a safetyinstrumented system designed to prevent overpressurization in piping
systems and processing facilities.

Safety Shutdown Valve Control System
Safeguarding wells and flowlines is a constant concern for operators no
matter what the environment. The operator must have total control of the
well at all times, being able to close the fail position of the valve upon
hydraulic pressure loss or to perform an ESD.
Designed with field service and minimal downtime in mind, the Cameron
safety shutdown valve control system can be adapted to work with other
components in various configurations. When an abnormal condition occurs,
the safety shutdown valve and controls must be manually reset to be
put back into service. A protective enclosure protects the system against
the elements.
Using a hand pump with various control components, a zero-leakage
circuit is maintained to ensure valve movement does not inadvertently
occur until a fail-safe signal is received. Controls are typically pilot tripped,
but solenoids also can be utilized for remote control where electricity is
available. The control must be manually reset after a fail-safe operation
has occurred.

DryAccess Deepwater Production System
In tension-leg platform (TLP) and spar top-tensioned riser (TTR)
applications, establishing reliable access to subsea wells from surface can
be a time-consuming challenge. In the early execution phase of a project,
thousands of hours in third-party engineering and interface management
can be required to ensure safe, reliable, and efficient access during the
well construction, operating, and production phases of the project.
DryAccess* deepwater production systems provide complete, seamless
integration of three critical vertical access interface systems from one
supplier, resulting in substantial cost savings for the operator. This solution

Chokes

Choke valves provide pressure and flow control across a wide range of applications,
such as wellheads, production manifolds, and choke and kill manifolds. We supply
various types of proven, durable choke valves for standard, erosive, and corrosive
service. A dedicated choke maintenance program and choke erosion monitoring
services enhance reliability.

Control Chokes
Cameron control chokes incorporate hydrodynamic energy dissipation
to reduce erosion problems while ensuring positive flow control. During
service, the flow enters the choke inlet and circulates around the annulus
between the body and cage. The cage has an even distribution of ports that
determine the maximum flow capacity.
The high-velocity fluid streams produced by the flow collide in the center
f the cage. Because the fluid streams impinge directly with each other, this
enables the most erosive energy to be dissipated. This in turn minimizes the
risk of erosion damage to downstream components.

Multitrim Chokes
With multiple trim options to suit changing conditions, Cameron
multitrim choke valves are suitable for a wide range of operations.
The modular design and easily interchangeable trim styles provide
chokes with enhanced versatility. Adapting the choke valve for different
modes of actuation does not require choke disassembly, minimizing
production downtime.
Chokes are frequently exposed to erosive wear because of sand and other
particles in the production fluids. If left unattended, washouts and choke
failures can result, endangering personnel and environmental safety as
well as causing loss of production. Multitrim choke valves offer full trim
interchangeability, enabling planned maintenance for increased uptime.
Changing trims saves the time and cost associated with purchasing
a different type of choke when well conditions change. The
multitrim choke valves have a significantly extended service life with
enhanced controllability due to innovative trim design and the use of
advanced materials. The result is more efficient production and less
formation damage.

Multistage Chokes
Multistage choke trim is used in applications in which high differential
pressures result in unacceptably high noise and vibration levels, especially
in gas service. Multistage trims are also commonly used to prevent
cavitation in the case of liquids, particularly for water injection.
The trim works by reducing the pressure over a number of discrete stages,
giving a carefully managed pressure profile. Similarly, it manages the
velocities within the trim and prevents the occurrence of undesired flow
effects such as sonic velocities and high-velocity jetting. A number of
multistage trim options are available.
