Introduction
Just what is an openhole completion? In a pragmatic sense, Baker Hughes defines openhole completions as a product line
encompassing liner hanger and external casing packer products. The products in the Baker Oil Tools division of Baker Hughes have a
natural “fit,” complementing each other perfectly from an applications approach. During a single operational sequence, a liner can be
run and anchored in the wellbore and, at the same time, zonal isolation can be achieved by advanced cementing and annular barrier
technologies. State-of-the-art seal designs ensure life-of-well performance and safety.
Openhole completions are an integral part of every drilling and completions engineer's tool bag. They allow operating companies to
reduce capital expense and minimize risk on a wide variety of applications. Strategic use of these technologies results in quantifiable
reduction in overall well construction costs and often improves well performance.
Baker Hughes has maintained its position as the industry leader by focusing on excellence—in technology, quality, and service. Our
engineering, manufacturing, marketing, and operations groups strive to discover innovative technologies that can be applied across the
board, from the most technically challenging high-pressure/high-temperature well to the infill drilling programs of mature fields. Our service
personnel are the most highly trained in the field; they understand how our tools function and are prepared to handle contingencies.

Premium High-Pressure/High-Temperature
Cemented Liner Completion
This premium liner hookup incorporates many modern innovative
features, ensuring reliable operation and service in today’s most
demanding high-pressure/high-temperature (HP/HT) openhole
completions. This liner is run on a HRD-E™ setting tool that allows
the liner to be worked to bottom.
The ZXP™ Ultra HP/HT compression-set liner top packer is a
redesigned ZXP packer intended for use in HP/HT applications.
The standard ZXP packer was redesigned to withstand the higher
pressures and temperatures encountered in today’s deep, hostile
environments. A solid, one-piece mandrel provides maximum burst
and collapse properties. Dual body lock rings lock in the FLEX-LOCK™
hold-down slips and ZX seal to limit any movement after the packer
is set.
The ZX seal has been modified for applications up to 500°F (260°C).
The seal has been lab tested to 16,000 psi (1103 bar). The LFC™ fourplug system allows the cement to be separated from the wellbore
and displacement fluids until it reaches the shoe.

Premium Cemented Liner Completion
With Hanger/Packer Tested To ISO V-0
Production Packer Specification
The UniFlex™ Pro liner hanger/packer is the industry’s first complete
liner hanger system for cemented liner applications. The hanger/
packer is built on a one-piece mandrel with no internal connections.
External moving parts are rotationally locked to the body, preventing
back-off of threaded outer components and damage to hydraulic
seals if extensive rotation of the liner is required to reach bottom.
The hydraulic-set rotating liner hanger requires no pipe rotation
to set, supports very heavy loads, and allows rotation of the liner
during cementing operations for an improved cement job. The
hanger/packer system complies with and has been tested to ISO
14310 grade V-0 production packer specification. The liner is run
on a HRD-E™ hydraulic release setting tool, which allows the liner
to be pushed, pulled, and rotated as required to work the string to
bottom. The ST landing sub allows setting of the hanger and release
of the running tool. After the HRD-E setting tool has been released,
the ball seat reduces the magnitude of the pressure spike when the
ball is expelled from the tool. Once pressure has been reached to
shift the tool and expel the ball, a rupture disk bursts, hydraulic oil
slowly bleeds through an orifice and provides adequate time for the
pressure to be reduced at surface before the ball seat extrusion. No
appreciable pressure spike hits the formation.

INLine Tight-Clearance Liners
A modern trend in wellbore construction involves reducing the size of
the steps between casing diameters. A significant reduction in overall
well cost often can be realized by using a low-annular-clearance
design. The INLine™ liner hanger/packer system was specifically
designed for installing tight clearance liners. INLine delivers a higher
hanging capacity and pressure rating than conventional equipment
of equivalent size. Higher ratings are achieved with the use of
FLEX-LOCK™-style slips, ZX™ packer element, and setting piston
that eliminates conventional concentric hydraulic cylinders, greatly
improving pressure integrity. INLine is run as a system with the Hyflo™
diverter valve, which is installed just above the liner in the running
string and auto-fill float collar. Auto-fill equipment and Hyflo diverter
valves enable casing to be run at much higher trip speeds without
the risk of formation breakdown. As the liner is run in the hole, fluid
is taken up through the inside of the liner and placed back into the
annulus above the liner through the Hyflo valve.

Premium Cemented Liner System
Baker Hughes has developed a liner system that greatly reduces
the risk of prematurely setting a conventional hydraulic hanger due
to circulation pressures exceeding the setting pressure of the liner
hanger. The ControlSET™ FLEX-LOCK™ III liner hanger uses the proven
design of the hydraulic set FLEX-LOCK hanger as a base model.
A redundant hydraulic cylinder balances out the setting forces,
allowing circulation at high rates without prematurely actuating the
hanger slips. Hydraulic activation of the system occurs when landing
a ball on seat within the running tool assembly while applying
pressure. The ZXP™ liner packer is designed to withstand extremely
high circulation rates, and high temperatures and pressures. The seal
is an annealed steel and elastomer element designed to eliminate
the possibility of swabbing off during high circulation rates. The liner
is run on an HRD-E™ hydraulic-release setting tool. The HRD-E allows
the liner to be pushed, pulled, and rotated during circulation as
required to ream the liner to bottom.

Versatile Cemented Liner Hookup
This liner assembly represents one of the most frequently run
hookups in the world. It is considered the standard in many regions
because of its ability to fit a variety of applications. The hydraulicset, rotating FLEX-LOCK™ III liner hanger supports heavy loads and
allows rotation of the liner during the cement job. The ZXP™ liner
packer provides the most rugged packing element in the industry.
The element allows high circulation rates and ensures a highperformance seal at the liner top. The COMPdril™ composite lead/
follow plug system allows the cement to be separated from the
wellbore and displacement fluids until it reaches the shoe. The
COMPdril system is beneficial in reducing contamination of the
cement slurry. The liner wiper plugs are securely attached to the
COMPdril running tool with fully supported lock dogs rather than
simple shear screws preventing premature release. The bodies of
the COMPdril plugs are molded with a high-strength composite
material and designed so that they can be drilled out easily without
compromising performance. The delayed-opening ball seat offers
a significant benefit, reducing pressure surge when the ball seat
releases. Pressure equalization requires several minutes, allowing
pressure reduction before the seat extrudes, preventing formation
damage that can occur with conventional ball seats placed at the
bottom of the liner.

running in the hole. The CMC handles moderate to heavy loads. Low
profile slips provide a large supported slip area and reduce potential
for damage while running liner in the hole. The CMC multi-cone
design provides excellent fluid bypass. The ZXPN™ compression-set
liner packer is a compact liner top packer using the field-proven
ZXP™ seal technology. The ZXPN is designed to withstand high
circulation rates, high pressure, and moderate temperatures. The
new composite solo plug and composite landing collar have been
designed to increase the reliability and performance of current
industry standard plugs while increasing the drillability of the shoe
track. The body of the solo plug is molded with a high-strength
composite material and designed for quick drillout. The CMC™ and
ZXPN are included in our worldwide liner hanger standardization list.
The standardization allows reduced delivery times, reduced cost, and
better worldwide common practices.

The liner and hanger assembly are run into the hole, the string
rotated to the left to actuate the hanger, and the liner weight slacked
off. The C-2 setting tool is released with right-hand rotation, and
then picked up to confirm release. Cement is pumped, followed by a
pump-down plug. The pump-down plug latches into the liner wiper
plug attached to the bottom of the running string, and together they
are displaced to the Type I landing collar just above the float shoe.
Cement is prohibited from re-entering the liner by check valves
within the shoe. With the cement in place, the running string is
picked up to expose the packer setting dogs, and slacked off to
energize the packer. With the liner top isolated, any excess cement
may be safely circulated or reversed from the wellbore.

the SLP-R can be released and retrieved with a fishing spear. The
SLP-R is run on the SLP hydraulic-release running tool. A mechanical
secondary release feature is incorporated, should the setting tool
fail to hydraulically release. The SLP-R drill-down version is very
similar to the standard SLP-R, but also allows low-torque, right-hand
rotation of the slotted liner before setting.

Many areas of the world experience considerable difficulty with
wellbore stability when it is time to run the liner. Sloughing shales,
unconsolidated sands, differential sticking and relief of tectonic
stresses—all may cause hole problems which require rigorous
rotation to ream the liner into the hole. This hookup includes
equipment which is specifically designed for this demanding
application. The SDD™ hydraulic set liner hanger is manufactured
with a rugged solid body, with excellent protection for the slips, and
a patented setting mechanism which requires no hydraulic cylinder.
Large, high-quality flow channels provide excellent bypass of cuttings.
The ZX™ packing element includes a bonded metal and elastomer seal
ring which is proven to withstand long periods of high rate circulation
and resist mechanical damage. The HRD-E™ setting tool’s high
torsional capacity allows high-RPM rotation when the liner must be
aggressively worked into the hole. The liner top debris barrier inhibits
settling of cuttings and debris in the tieback extension, which could
potentially cause the setting tool to become stuck.
Liner Drilling Applications
Expandable Liner Hanger System

interchanged to meet specific well applications. Baker Hughes’
TORXS™ liner hanger system is a fully integrated expandable liner
hanger system that has been designed for the broadest range of
applications without modification or retrofitting of components. As is,
the system can be used for extended-reach liners, drill/ream/washdown liners, heavy- and lightweight liners, as well as most other
liner applications.

TORXS is the industry’s first expandable hanger system that doesn’t
compromise operational risks. TORXS is the only expandable hanger
system on the market allowing the operator to run and rotate as
necessary, hang the liner, release the running tool, cement the liner
and optionally set the packer. This is accomplished without relying on
a plug bump to activate the setting of the hanger or packer or release
of the setting tool. And, because the entire system is pressurebalanced, there is little concern of prematurely setting the hanger
or releasing the setting tool while working a liner in the hole. This
feature, along with maximized bypass areas, high torsional capacity,
no mechanisms exposed to annular fluid flow, and no hydraulic ports
in the hanger body, makes TORXS a better option than conventional
equipment for many well conditions.
The TORXS liner hanger packer is run in on the TORXS liner setting
tool. Upon reaching setting depth, a setting ball is dropped from
the surface and allowed to land on an extrudable ball seat in the
setting tool. Applied pressure will actuate a swage mechanism on
the setting tool causing the hanger body and slips to expand, making
permanent contact to the casing string. Circulation is established
and cementing of the liner can be performed. After cementing, the
drillpipe is reciprocated to close a flapper in the setting tool. Pressure
is applied to the flapper and the swage is actuated to expand the ZX™
seal, making full permanent contact to the casing ID. Once the packer
is set, an increase in pressure will burst a rupture disc in the flapper
seat, allowing the run-in string to be pulled from the liner top. A liner
top test can be performed before coming out of the hole if desired.

Drill-In Liner
The EZLine™ liner drilling system for Baker Hughes delivers casing
and liner across tough, problematic zones. The system integrates
Baker Hughes’ fluids, EZCase™ casing bits, and the field-proven liner
hanger system. The combination of drilling bit and casing in one
run eliminates the need for a dedicated milling trip, and allows the
system to drill to bottom and be cemented in place in one trip. With
a full PDC cutting structure and special alloy crown, the EZCase
bits are strong enough to drill through problematic formations, yet
are drillable with a milled tooth or custom PDC bit. The high-torque
capability of the liner hanger running tool is ideal in reaching total
depth of drilled hole for a variety of difficult formations, including
depleted formations, unstable formations, and loss zones. The simple
proven design of the EZLine liner drilling system is the best choice for
applications where ordinary methods won’t work.

Drilldown Liner System
The Drilldown liner assembly is the most robust conventional liner
system in the industry and is configured to eliminate any possibility
of setting the liner hanger prematurely due to high circulation
pressure or pressure surging. The Drilldown ControlSET™ FLEX-LOCK™
liner hanger outside parts are rotationally locked so that there is
no movement during drilling. Carbide wear buttons placed on the
top and bottom of the hanger provide the cylinder and slips better
protection during drilling. The ZXPD™ compression set liner packer
is a compact liner top packer utilizing the field proven ZXP™ seal
technology. It is designed to withstand extremely high circulation
rates, pressures and moderate temperatures. All outside parts are
rotationally locked so that there is no movement during drilling
and carbide wear buttons provide the seal with protection during
drilling. The EZCase™ casing bit has the most reliable PDC cutting
structure that can be drilled out with either a roller cone bit or a
PDC bit. EZCase bit are manufactured from a specialized steel alloy
that allows PDC cutter to be brazed directly to the one piece bit. The
HRD-E™ setting tool allows the liner to be pushed, pulled, rotated
during circulation as required to drill the liner to bottom.

The Steerable Drilling Liner (SDL) features the capability to run a
liner while drilling with an AutoTrak™ Rotary Steerable System.
This technology allows the casing to be run when drilling to target
while saving extra trips and avoiding interruption when compared
conventional drilling operation. Unlike conventional drilling liner
system, the SDL incorporates the technology leading AutoTrak
Rotary Steerable System allowing for liner drilling of a reservoir
with tight targets. With Baker Hughes field proven liner hanger
system and PDC bit technology, this combination provides for a
Best-In-Class system for liner drilling. The system features the
ability to change the inner bottom hole assembly if needed while
the liner remains downhole.

Coiled tubing has become a cost-effective method of sidetracking
or deepening wells through the existing production tubing. In
many cases, coiled tubing offers reduced rig-up and operating
expense when compared to a drilling or workover rig. Deploying and
cementing liners in these wellbores has become commonplace, due
to the development of dedicated CT liner systems by Baker Hughes'
openhole completions group. Liners (2-3/8 in. (60.3 mm), 2-7/8 in.
(73.0 mm), and 3-1/2 in. (88.9 mm)) are routinely run on coiled tubing
through 4-1/2 in. (114.3 mm) production tubing.
Because rotation of the coiled-tubing bottomhole assembly (BHA) is
not practical during liner operations, all primary tool functions must
be hydraulic. The CT liner setting tool is used in conjunction with a
special CT setting sleeve to carry the liner into the hole on a fully
supported collet system, similar to the reliable HR™ setting tool (HR).
Other standard coiled tubing BHA components are run above the CT
setting tool, such as a coiled-tubing connector, tubing swivel, and
hydraulic disconnect.
Since many of these ultra-slimhole liners are set horizontally, a liner
hanger may not be required. These liners are typically set on bottom.
After pumping down a setting ball, pressure is applied to the coil and
the CT setting tool is released. A miniature coiled-tubing pump-down
plug wipes the coil, mates with the appropriate liner wiper plug, and
is pumped to the landing collar as the cement is displaced.

fluid types in uncemented open hole completions. Baker Hughes'
patented HMR™ Horizontal Inflation Tool (HIT) is designed to
positively locate and inflate multiple ECPs with cement or other
desired inflation fluids. The HMR HIT assembly also prevents loss
of cement from the inner string while moving between ECPs and
permits excess cement to be circulated from the wellbore after
final inflation. The HIT assembly may be run on an inner string
during the initial liner installation, permitting single trip setting
and inflation of packers as the running string is pulled out of the
hole. The HMR HIT assembly can also be used to inflate ECPs on a
second trip if desired.

In many openhole completions, operators require positive cement isolation
above the production interval. An ECP™ and pressure-actuated cementing
(PAC) valve run in tandem can provide the desired isolation. The PAC
valve is used to perform a stage cement job just above the slotted pipe or
wire wrapped screen. The valve opens and closes hydraulically; no pipe
manipulation is necessary to operate. An ECP is required to isolate the
slotted pipe or screen from the cement job above. Compatibility between
liner setting tool, PAC valve closing seat, landing collar, and plugs must be
verified before the installation.

Based on tubing movement calculations, it may not be desirable to
use a floating seal assembly on the production tubing. This hookup
allows the tubing seal assembly to be anchored into the liner top,
but provides a reliable method of spacing out to land the tubing at
surface. Standard production tubing jewelry and safety systems can
be used, eliminating the need for additional specialized equipment.
First, a standard liner assembly is run, set, and cemented in place.
On the second trip, a double-grip JMZX™ liner tieback packer with a
special snap-in/snap-out shear-release-compatible S™ liner setting
sleeve is run, stabbed into the existing liner top, and set. The
double-grip JMZX liner tieback packer includes premium features
such as the patented ZX™ seal element, opposing FLEX-LOCK™
slips to accept axial loading in either direction, and the highly
dependable Bullet Seal™ technology. The setting mechanism of the
JMZX requires no setting balls, blanking plugs, or rotation.
On the final trip, a completion-type snap-in/snap-out, shear-release
anchor seal assembly is run on the completion string, along with any
other jewelry and safety valve as required. After the necessary space
out is determined using the snap-in/snap-out feature, the tubing
is landed and the seal assembly is anchored in place. No rotation
is required during this completion process. The seal assembly can
be furnished with rotational and/or shear release, for redundant
methods of retrieving the tubing should the well require workover.

Inner String Cementing
for Large-Diameter Liners
Large-diameter cemented liners are becoming a common practice
because of increased drilling activity in deep water. Historically,
shallow gas was covered with the 13-3/8-in. casing string. Today,
16-in. liners are typically used to case off shallow gas in deep water.
Baker Hughes uses the hydraulic-set FLEX-LOCK™ liner hanger for
all large-diameter liners. Inner string cementing reduces cement
contamination and reduces displacement time. The inner string
equipment is designed for cementing large diameter liners through
tubing or drillpipe inner string. The inner string eliminates drilling
out large quantities of cement. The inner string extends down to the
bottom of the liner and provides better displacement accuracy than
16-in. liner wiper plugs. The small pump-down plugdrills much faster
than large 16-in. liner wiper plugs.

When a major North Sea operator wanted to run a very heavy
liner in an extended reach horizontal well, they were faced with
a number of significant challenges. Equivalent Circulating Density
(ECD) had to be watched closely due to the narrow fracture gradient
to pore pressure window. Hole drag in the horizontal section would
be an issue, based on modeling and field experience. Due to the
high-profile nature of the project, it was preferable to use as much
proven equipment as possible.
A decision was made to design a Mud-over-Air (MoA) floating liner
system. This would effectively reduce the weight of the liner casing
in mud from 43.4 lb/ft (64.7 kg/m) to only 6.3 lb/ft (9.4 kg/m) with air
inside the liner. This would greatly reduce friction between the liner
and the borehole wall.

Over 14,950 feet (4,560 m) of 9-5/8 in., 53.5 lb/ft (79.8 kg/m) liner
casing was run with local standard FLEX-LOCK™ hydraulic set liner
hanger, ZXP™ liner top packer, and RS™ nipple. The modified hookup
also included a polished bore receptacle to provide an additional
sealing location below the hanger. The liner was run in on a
conventional HRD-E™ hydraulic release liner setting tool, with dual
ST™ landing subs, a ported sub and dual packoffs as shown. The
lower ST landing sub was modified with a single bore trip ball, which
provided the isolation between the air and mud while floating the
liner in.
To provide necessary weight and rigidity to push the liner into
the hole, 6-5/8 in. (168.3 mm) drill-pipe was used. The 6-5/8 in.
(168.3 mm) was kept full from the ST landing sub to surface on
the trip in. When the liner reached TD, pressure was applied to
trip the lower ST sub, and the entire hole was filled and stabilized.
Normal liner hanging and cementing operations were carried out
per standard operational practice, and the liner top packer was set
and successfully tested. The operator is able, using Baker Hughes'
technology and the MoA technique, to reach target bottomhole
locations that would typically require at least one more casing point.
Savings in capital and rig expense are notable.

If a hydraulic seal cannot be achieved by either cement or a liner top

existing tieback extension in the well, a tieback packer may be run to
remedy the leak.
The first run is made with a casing scraper and tandem tieback mill
assembly. The casing scraper is worked across the packer setting
depth, while the polishing mill cleans the ID of the sleeve and the top
dress mill removes any potential burrs or damage.
On the second run, a ZXP™ liner tieback packer with seal assembly
is run with the corresponding setting tool. After the seal assembly
is stabbed into the tieback extension, a pressure test is performed.
After successful pressure test, set the ZXP packer. A final pressure
integrity test is preformed. If required, a negative or inflow test can
be performed on the same trip using a Retrievamatic™ test packer,
run above the liner setting tool. Elimination of an additional trip
considerably reduces rig time and expense.

ControlSET FLEX-LOCK III Hydraulic-Set
Liner Hanger
Product Family No. H29416
APPLICATION
Various regions of the world have historically experienced difficulties
getting liner systems to target depth due to well conditions that
inherently result in a stuck liner. The practice of washing and reaming
liners through these difficult hole sections is a proven technique for
getting liners to bottom. However, a significant risk increase exists of
prematurely setting a conventional hydraulic hanger due to circulating
pressures exceeding the setting pressure capabilities of typical
hydraulic hangers.
Baker Hughes has developed a liner system that greatly reduces the
risk of reaming or partially drilling a liner to total depth. Using the
proven design of the hydraulic-set FLEX-LOCK™ III hanger as a base
model, modifications were then implemented to produce a robust
and functional system. A patented, redundant hydraulic cylinder,
which balances out the setting forces, was developed to allow the
liner to be run in, while circulating at high rates, without prematurely
actuating the hanger slips. Hydraulic activation of the system occurs
when landing a ball on seat within the running tool assembly while
applying pressure.

FLEX-LOCK III Hydraulic-Set Liner Hanger
Product Family No. H29410
APPLICATION
The patented FLEX-LOCK™ hydraulic-set liner hanger series is capable of hanging
exceptionally heavy liners. This unique hanger can be provided as a complete
assembly, or in kit form. The kit is installed without welding onto a standard
FLEX-LOCK body, a joint of liner casing, or on a polished bore receptacle body.
The FLEX-LOCK liner hanger is ideal for liner applications where corrosionresistant alloys (CRAs) are used. The FLEX-LOCK kit can be mounted directly onto
the CRA casing, representing a significant savings over a CRA solid body hanger.
Like the familiar HMC™ hydraulic liner hanger, differential pressure across an
integral hydraulic cylinder strokes the slips into engagement with the casing.
The dramatic increase in hanging capacity over cone-type hangers results
from state-of-the-art design and finite element analysis study. Loads transfer
circumferentially into the slip seat, rather than radially inward to the mandrel as
the liner weight is hung. High load stresses on the mandrel beneath the slips are
avoided, preventing collapse of the hanger body under heavy loading. Stress hot
spots in the parent casing are eliminated.
FLEX-LOCK III Hydraulic-Set Rotating Liner Hanger
Product Family No. H29410
APPLICATION
The FLEX-LOCK hydraulic-set rotating liner hangers incorporate a tapered roller bearing
assembly that allows the liner to be rotated with the hanger in the set position while

HMC Hydraulic-Set Liner Hanger
Product Family No. H29223
APPLICATION
The HMC™ hydraulic-set liner hanger is the standard by which all
other modern liner hangers are compared. It is set hydraulically by
applied pressure through the run-in string, and is designed to support
medium to heavy liner loads. The hanger is widely used in deep and
high angle wells, where actuation of mechanical-set hangers may not
be preferred. A setting ball is dropped and/or circulated to a ball seat
in the landing collar or running string. Differential pressure acts on
the hydraulic cylinder, moving slips up the cones to the set position.
The high-strength hydraulic cylinder is designed to provide high burst
and collapse resistance. Recent upgrades to the HMC include a
positive cylinder stop and premium FLEX-LOCK™-style cylinder seals.

Liner Hangers
SDD Hydraulic-Set Liner Hanger
Product Family No. H29262
APPLICATION
There are formations that are absolutely uncooperative when it’s time to run
the liner. The string may require aggressive rotation for many hours to be
worked to depth. The SDD™ hydraulic-set liner hanger is designed as the most
rugged hanger available to the industry for these applications. The solid hanger
body is machined from one piece to ensure durability, complete protection for
the slips, and quality fluid bypass for unimpeded circulation of cuttings and
debris. FLEX-LOCK™-style slips are standard to provide high load capacities.
The hanger slips are actuated by discrete pistons, rather than by a hydraulic
cylinder. As a result, fluid courses may be milled as deep as the OD of the liner
between the slip cavities. In most sizes, burst and collapse ratings equal to
mechanical-set hangers can be achieved since there is no hydraulic cylinder.
The aggressive cutting shape of the skids helps to break up cuttings while
working the liner down. Carbide buttons reduce OD wear.
Advantages





Robust solid-body design allows rotation at high torque
and RPM, with total protection from slip damage
Quality bypass allows high circulation rates and removal
of larger cuttings without packing off
Slips tied to a common activator ring, ensuring uniform
contact with casing. Pressure acting on the setting pistons
generates force to stroke activator ring
Compact design reduces pressure drop and minimizes rigid
tool length when working through dog legs
Elimination of hydraulic cylinder improves burst and collapse
ratings over conventional hydraulic-set hangers

SDD™ Hydraulic Hanger
Liner Hangers
FLEX-LOCK III Mechanical-Set Liner Hanger
Product Family No. H29413
APPLICATION
The patented FLEX-LOCK™ mechanical-set liner hanger series is capable of hanging
exceptionally heavy liners. This unique hanger can be provided as a complete assembly,
or in kit form. The kit is installed without welding on a standard FLEX-LOCK body, a
joint of liner casing, or on a polished bore receptacle body. In effect, the liner casing is
the mandrel of the hanger. A single kit may be mounted on a variety of mandrels with
different threads, weights, or grades.
FLEX-LOCK mechanical-set liner hangers are ideal for liner applications where maximum
burst and collapse pressure ratings are required. The FLEX-LOCK kit can be mounted
directly onto corrosion-resistant alloy casing, representing a significant savings over
a corrosion-resistant solid body hanger. The improved drag spring/J-cage assembly is
available for right- or left-hand setting, and reduces presetting compared to pin-type
actuation mechanisms.
The dramatic increase in hanging capacity over cone-type hangers results from stateof-the-art design and finite element analysis study. Loads transfer circumferentially
into the slip seat, rather than radially inward to the mandrel as the liner weight is hung.
Load stresses on the mandrel beneath the slips are eliminated, preventing collapse of the
hanger body under heavy loading. Stress hot spots in the parent casing are eliminated.
Excellent circulation is achieved through fluid courses located in the slip seat and behind
the slips. Flow area is the same after setting the hanger as in the run-in position.
FLEX-LOCK III Mechanical-Set Rotating Liner Hanger
Product Family No. H29413
APPLICATION
The FLEX-LOCK mechanical-set rotating liner hanger incorporates a tapered roller
bearing assembly that allows the liner to be rotated with the hanger in the set position
while cementing the liner. This bearing package allows the liner to be rotated at higher
RPM than hangers incorporating conventional ball or journal bearing systems.

RCM 2 Mechanical-Set Rotating Liner Hanger
Product Family No. H29226
APPLICATION
The RCM 2™ mechanical-set rotating liner hanger is a light- to medium-duty cone-type hanger
that allows rotation after the liner is hung. The tapered roller bearing assembly is designed and
constructed to ensure rotation in high-temperature environments. The liner may be rotated at
higher speeds than when using hangers employing conventional ball or journal bearings.
The automatic J-cage allows the hanger to be reset if required. A rotating 2 RH™ or HR™ setting
tool is used to set the hanger with right-hand rotation. After the hanger is set, the setting tool
is released. The liner may now be rotated through the hanger during the cement job. The RCM 2
version includes a one-piece mandrel and optimized slip load distribution.
Advantages




Tapered roller bearing allows liner to be rotated in the set position
T-slot bowsprings eliminate use of set screws in the J-cage
Material suited for H2S service available upon request
Automatic J-cage allows simple resetting of hanger to run-in position

Liner Top Packer
Product Family No. H29643
APPLICATION
The ZXP Ultra™ compression set liner top packer is a redesigned ZXP™
liner top packer intended for use in high pressure/high temperature
applications. The standard ZXP Packer was redesigned to withstand
the higher pressures and temperatures encountered in today's deep,
hostile environments. The cone under the ZX™ seal is integral to the
body and located near the lower end of the packer. The one piece
mandrel provides maximum burst and collapse ratings. The ZX seal
has been modified with dual PEEK* seal rings molded in to the
AFLAS* seal element and high temperature element for application
up to 500ºF. The PEEK rings act as a secondary barrier to the metal
to metal element to prevent cold flow of the elastomer in high
temperature applications. The hold down slips are standard
FLEX-LOCK™ slips for maximum casing bite and will withstand high
end loads during high pressure production cycles.

ZXP Liner Packer
Product Family Nos. H29625, H29629, H29645, and H29648
APPLICATION
The patented ZXP™ liner packer is recognized industry-wide as today's premier high-performance
liner top packer. More than 35,000 successful installations over the last decade have established
the ZXP as the industry leader in annular sealing technology.
The innovative ZX™ seal element is designed and constructed to endure exceptionally high
circulation rates and achieve high-pressure and -temperature sealing in the most demanding wellbore
environments. Flow loop testing at over 17 bpm (2.7 m/min) confirms durability of the ZX seal.
An elastomer sheath is bonded to a unique metal cylinder, which is swaged by a cone out to the casing wall
during the setting process. Raised tangs on the circumference of the metal ring make full-circle contact with
the casing ID, trapping the elastomer cover and preventing extrusion as differential pressure is applied.
The ZXP liner packer is typically run as an integral component of the primary liner hookup. It may also be
run in conjunction with a tieback seal assembly to serve as a tieback packer in the event remedial repair
of the liner top is necessary. The packer is compression-set using a packer setting dog sub or a hydraulic
pusher tool.
The ZXP liner packer is available with or without hold-down slips. ZXP packers can be run on 2 RH™, and
HRD-E™ liner setting tools. tieback extensions are commonly available in lengths of 6 ft (1.82 m),
10 ft (3.04 m), 15 ft (4.57 m), and 20 ft (6.09 m). Other lengths available upon request.

ZXPN Liner Packer
Product Family Nos. H29640 (2 RH Profile), H29646 (HRD-E Profile)
APPLICATION
The Baker Hughes ZXPN™ liner packer is a compression-set liner top packer that uses a modified ZX™ packing
element design. The seal element for the ZXPN is molded with a nitrile elastomer for a high pressure rating,
high circulation rates, but for moderate temperatures. The annealed steel and elastomer ZX element is
actuated by applying set-down weight to the tieback extension, via the setting dogs on the liner running
tool. This force drives the ZX seal up the cone ramp, causing it to expand and conform to the casing ID. The
element’s external tooth profile will seal off any extrusion gap, trapping the setting force between the teeth
and preventing cold flow of the elastomeric cover. A body lock ring system incorporated in the ZX seal holds
a permanent set in the seal once actuated. The packer will provide an effective annular seal between the
top of the liner and the casing, thus preventing possible formation breakdown, loss of cement slurry and gas
migration above the liner top during cement cure.
The ZXPN liner packer is typically run as an integral component of the primary liner hookup. The ZXPN may
also be run in conjunction with a tieback seal assembly to serve as a tieback packer in the event remedial
repair of the liner top is necessary. The packer is compression-set using a packer setting dog sub or a
hydraulic pusher tool.
The ZXPN can be run on a 2 RH™, or the HRD-E™ liner setting tools. Tieback extensions are commonly
available in lengths of 6 ft (1.82 m), 10 ft (3.04 m), 15 ft (4.57 m) and 20 ft (6.09 m).

ZXPD Liner Packer
Product Family No. H29646 (HRD-E Profile)
APPLICATION
The ZXPD™ compression set liner packer is a compact liner top packer
using the field proven ZXP™ seal technology. It is designed to withstand
extremely high circulation rates, pressures, and moderate temperatures.
All outside parts are rotationally locked so that there is no movement
during drilling. Carbide wear buttons placed on the top and bottom of
the packer provide the seal with protection during drilling. The annealed
steel and elastomer ZX™ element is actuated by applying set-down
weight to the tieback extension, via the setting dogs on the liner running
tool. This force drives the ZX seal up the cone ramp, causing it to expand
and conform to the casing ID. A body lock ring system incorporated in the

Liner Hanger Packers
TORXS Expandable Liner Hanger System
Product Family No. H29337
APPLICATION
TORXS™ is a new addition to the industry’s largest selection of liner hanger
solutions. It is the only expandable liner system that can be installed
conventionally, without requiring a critically timed high-pressure plug bump
as the primary activation method for the hanger or packer, or for release
of the setting tool. This minimizes the risk of poor-quality liner-to-cement
bonding that can occur when a liner is ballooned with a high-pressure plug
bump. Also, there is no need to compromise the optimum cement formulation
with additional retarders or other additives that extend the cementing pump
time–a common practice with plug-bump-dependent systems.
Deployment of TORXS is simple:




Run, circulate, and rotate into the hole as necessary
Hang the liner and release from the setting tool
Cement the liner
Set the packer
All setting mechanisms are integral with the setting tool. The multiple
hydraulic setting cylinders provide downhole setting force to the adjustable
swaging cone, enabling it to independently expand the hanger and annular
seal. First, the swaging cone expands the hanger body to engage the
mechanical slips into the casing–before displacing cement. The running tool
is released before cementing. After cementing, the swaging cone expands
the packer body to energize the ZX seal against the casing before the
cement sets.
Advantages






Expandable liner hanger/packer system that is applicable to
most liner scenarios
Hydraulically balanced system that eliminates presetting
while circulating in the hole or during cementing placement
High-torsion capacity capable of liner drilling or robustly
working liner through difficult hole sections
No annular mechanisms that risk malfunction with cuttings or
debris circulated up the annulus
All hydraulic system that does not require drillpipe weight to
set the packer.
Little or no reduction in annular circulating area with hanger
set versus unset, to minimize pressure drop across hanger
during circulation and cementing

Product Family Nos. H29314 (2 RH Profile), H29345 (HRD-E Profile)
APPLICATION
A modern trend in wellbore construction involves reducing the size of the steps between casing
diameters. Often, a significant reduction in overall well cost can be realized by using this “low
annular clearance” design. Historically, the performance ratings of liner hanger assemblies in these
casing combinations were marginal because of limited wall thickness available. Burst/collapse
pressure ratings and hanging capacities were often inadequate to meet project requirements.
Baker Hughes designed the INLine™ liner hanger/packer system specifically to address the challenges
of installing tight-clearance liners. With the INLine system, you get nearly twice the load capacity
and significantly improved pressure integrity over conventional equipment of equivalent size. The
standard 11-3/4-in. x 13-3/8-in. INLine has a million-pound load capacity (454 metric tons) and a
5,500-psi (379-bar) pressure rating to handle the most demanding tight-clearance application.
To achieve these high-performance ratings, we combined several leading edge technologies into a
single tool. The INLine system is composed of:




SLP-R Slotted Liner Hanger/Packer
Product Family Nos. H29307, H29309, H29310, and H29367
APPLICATION
The SLP-R™ slotted liner hanger/packer is a light-duty hanger/packer designed primarily for running
a slotted liner in horizontal well applications. The tool is set hydraulically, and if desired, may be
straight-pull released with a fishing spear.
The SLP-R is available in three basic configurations. The standard SLP-R (product family no. H29307)
is run on the SLP™ hydraulic release running tool (product family no. H26532) on drillpipe. The hanger/
packer is set with applied pressure through the running string. A mechanical secondary release
feature is incorporated should the setting tool fail to hydraulically release. The drill-down version
(product family no. H29309) is very similar to the standard SLP-R, but also allows low-torque, righthand rotation of the slotted liner before setting. The third type, HRD-E™ Compatible (product family no.
H29310) is designed to be run on an HRD-E setting tool (product family no. H29367), and is set using
a hydraulic pusher tool (product family no. H26534). The HR compatible version is favored when more
aggressive rotation may be required to work the liner to bottom.

Liner Hanger Packers
3D Liner Hanger/Packer
Product Family No. H29308
APPLICATION
The 3D™ liner hanger/packer serves as both a liner hanger and packer when the liner is not to be
cemented. As the slips hang the liner, the packing element is also compressed to seal against the
casing ID. The 3D liner hanger/packer is available with a single J-slot for right- or left-hand setting.
An internal lock ring permanently maintains setting force.
The 3D may be used as the lower packer on a scab liner to isolate damaged casing. It is typically run
below a compression-set liner packer such as a Hyflo™ III liner packer with hold-down slips. First the
3D liner hanger/packer is actuated and set, and the liner setting tool is released. After picking up to
expose the packer setting dogs, the upper liner packer is set by slacking off drillstring weight.
Another popular application for the 3D liner hanger/packer is as a large-bore injection packer on
disposal wells. The 3D provides the largest ID available for injection packer applications.
Advantages






Economical, one-piece hanger and packer for uncemented liners
Reliable single-slot J-cage allows slips to be reset to the run-in position
Standard internal lock ring locks in setting force
Optional cone-grip slips prevent upward movement after setting
Ideal for use as lower packer of scab liner to isolate damaged casing
Can also be run upside-down and pulled in tension for shallow scab liners

Liner Hanger Packers
JMZX Liner Tieback Packer
Product Family No. H27228
APPLICATION
Many innovative features combined with Baker Hughes' patented
ZX™ sealing system make the JMZX™ liner tieback packer the most
advanced tieback packer on the market. The JMZX is typically run
using a setting sleeve and setting tool on drillpipe. Upon running into
the existing liner tieback extension, the integral seal stem is inserted
until seated and pressure-tested down the work string. Additional
slackoff weight trips the collet lock nose and actuates the packer.
The setting tool is released after an annular pressure test. The JMZX
is also commonly used when tying back a liner to surface, or when
scabbing across damaged casing above the liner.
Three state-of-the-art technologies are incorporated
in the JMZX design:



Innovative ZX seal offers unsurpassed pressure and temperature
ratings and rugged dependability. The bonded elastomer and metal
seal element is highly resistant to swaboff and mechanical damage
while running in the hole.
Proprietary Bullet Seals™ on the seal stem ensure high-pressure
integrity even after repeated hot-stabbing into the tieback extension.
FLEX-LOCK™ slips provide maximum hold-down capacity without
damaging casing or packer mandrel. Double-grip slips available to
accept exceptionally high tensile or compressive forces, preventing
potential overload of existing liner hanger.
Advantages






Product Family Nos. H29546 (C-2), H29507 (2 RH), and H29552 (HRD-E)
APPLICATION
The S sleeve with tieback extension is primarily designed to be used
when setting a liner and tying back to surface is planned (two-stage
long-string). When tieback is completed, using the metal-to-metal
tieback stem, the integrity of the liner top will be equal to the liner.
S Sleeves are available with C-2™ (product family no. H29546), RH™
(product family no. H29507), which are located near the top of the
sleeve. The carrying profile and honed bore are constructed from one

The CT™ liner setting sleeve, used with a CT setting tool (product family
no. H26607) allows slimhole liners to be deployed on coiled tubing.
The CT setting sleeve and CT setting tool are very similar in function to
the familiar HRD-E hydraulic release system. The weight of the liner is
carried on a hydraulically released collet, rather than on threads, since
the setting tool cannot generally be released with rotation on coiled
tubing on the primary liner run. The liner can be pushed or pulled while
running into the hole. It is ideal for use in through-tubing horizontal
sidetrack applications. One-piece setting sleeve may be ordered with
or without the honed bore below the collet profile to facilitate landing
tieback or production seals. Optional slots at the top of the setting
sleeve body accept torque if backup release of the CT setting tool is
required. Available for use with 3-1/2-in. and smaller liners.

Liner Setting Tools
APPLICATION
Liner setting tools provide the physical attachment between the running string and the liner. The setting
tool is run in conjunction with a liner setting sleeve or liner top packer with the corresponding setting
tool profile. Together, they perform several key functions during liner running and cementing operations:
1. Support the weight of the liner while running in the hole.
2. Ability to push, pull, and circulate freely until release is desired.
3. Reliable releasing mechanism (mechanical, hydraulic, or both) to detach running string once liner
is in desired position.
4. Some tools allow rotation of liner before and after release.
5. As required, provide ability to set liner top packers after setting tool release.
Advantages

Torque fingers on certain tools permit liner to be rotated, helping to work liner to
bottom or allowing rotation during cementing for improved placement of slurry
HRD-E Liner Setting Tool
Product Family No. H26680
APPLICATION
The HRD-E™ liner setting tool incorporates most of the features found in the field-proven
HR™ liner setting tool (product family no. H26666). The HRD-E is designed to transmit greater
torque and compressive loads from the running string to the liner in more demanding applications,
such as reaming a liner to bottom through badly sloughing formations. In certain regions, the
HRD-E has been successfully used in conjunction with a specially designed drill bit liner shoe
to literally drill a liner through new formation intervals.
The increased torque rating of the HRD-E liner setting tool is achieved by increasing the number
and the length of the torque fingers as compared to the equivalent HR liner setting tool. Additionally,
the fingers are milled directly into the OD of the setting tool housing, increasing the housing's rigidity.
Considerably greater compressive loads can be applied from the running string to the liner, due to the
aggressive load shoulder configuration. The liner setting sleeve or liner top packer must be specifically
ordered for use with the HRD-E liner setting tool.

2 RH Liner Setting Tool
Product Family No. H26523
APPLICATION
The 2 RH™ liner setting tool is designed to run all types of mechanical
and hydraulic-set liner hangers. The 2 RH tool uses a left-hand
threaded nut assembly, with a spring-loaded, splined clutch that
prevents rotation of the nut until the tool is compressed. With the
tool in tension, right-hand torque may be applied to set right-hand
mechanical hangers, and then weight is slacked off to allow right-hand
release of the setting tool.
A special rotating version of the 2 RH liner setting tool is available to
be used with rotating liner hangers for improved cementing operations.
Eight additional turns to the right after the float nut has released will
rotationally lock the setting tool, permitting torque to be transmitted
through the torque fingers to the setting sleeve.

C-2 Liner Setting Tool
Product Family No. H26521
APPLICATION
The C-2™ liner setting tool is used to run, set, and cement liners, as
well as to activate liner top packers. A splined, left-hand threaded nut
engages left-hand threads in the setting sleeve to support the liner
as it is run. The nut is supported by a bearing system to allow easy
right-hand release of the running string after the liner hanger is set.
A sealing packoff system is included to direct the flow of mud and
cement down through the liner, rather than up past the setting tool. If
a compression-set packer is run with the liner, then the setting tool is
raised after cementing is complete to expose the packer setting dogs.
The running string is then slacked off and weight is applied to the
tieback extension to set the packer.

Hydraulic Pusher Tool
Product Family No. H26534
APPLICATION
In some applications, it may not be preferable to use a conventional packer setting dog sub to
set the liner top packer. The hydraulic pusher tool is designed to generate the required packer
setting force downhole with applied pressure on the running string. The hydraulic pusher tool
is commonly used with slotted or uncemented liners, for example, with the SLZXP™ slotted
liner hanger packer (product family no. H29635); it is also frequently used to set standard
compression-set packers such as the ZXP™ liner top packer when used as a tieback packer.
The hydraulic pusher tool may be used with cemented liners that are intended to be
reciprocated. The liner setting tool remains attached to the liner during cementing operations,
and anchors the pusher tool while setting the packer.
Advantages



packer itself, improving packer burst and collapse pressures
Available to set liner packers from 5 in. to 11-3/4 in.
Liner Top Debris Barrier
Product Family No. H26543
APPLICATION
The liner top debris barrier is designed to prevent cuttings and other debris from entering the
tieback extension, which could potentially settle out and stick the liner setting tool. The liner
top debris barrier remains positioned in the top of the tieback extension until cementing is
complete, when it is shear released and retrieved with the running string. Fluid enters and exits
the extension through the screen section, preventing potential collapse of the tieback extension.
Available to fit most extension IDs from 5.000 in. to 11.500 in. (127 mm to 292.1 mm).

Hyflo Surge Protection System
Product Family No. H26547
APPLICATION
Often, tight clearance liners are incorporated into the well plan to
reduce overall well cost. One challenge faced when installing these
liners involves hydrodynamic pressure surging. The liner, acting as
a large piston, requires slow trip speeds and frequently contributes
to expensive fluid losses. In the past, the solution was to run simple
auto-fill float equipment and allow some of the displaced mud to flow to
surface through the ID of the liner and drillpipe. The technique helped,
but did not effectively solve the problem, and certainly made a mess on
the rig floor.
Baker Hughes' Hyflo™ surge protection system has helped operators
of tight clearance projects improve operating efficiency and reduce
installation cost/risk. Integral to the system is the Hyflo diverter valve
(product family no. H26547), which is installed just above the liner in the
running string. Together, these devices eliminate surging at all practical
liner running speeds.
While running into the hole, mud is allowed to flow up the ID of the
liner and liner setting tools, and then is diverted to the drillpipe annulus
immediately above the liner hanger assembly. This provides maximum
flow area from TD to the surface and directs displaced mud returns to
the pits. Once the liner is at setting depth, the Hyflo diverter valve is
shifted closed by pressuring against a setting ball. The system includes
an autofill float collar. Pressure is applied to activate any hydraulic
devices necessary, and additional pressure activates a releasing
mechanism to convert the float valves to the normal “back pressure
valve” function. The Hyflo diverter valve includes an extrudable seat
that reliably passes balls and pump-down plugs at specific pressures.

Packer Setting Dog Subs
Packer Setting Dog Subs
APPLICATION
Packer setting dog subs are used to activate and pack off compression-set liner top
packers. Multiple spring-loaded dogs are compressed within the packer extension
throughout liner running and cementing. At the appropriate time, the setting dog
sub is raised out of the packer extension and the dogs expand out to the OD of the
extension. Setting force is transferred through the dogs and onto the packer extension
as drillpipe weight is slacked off.
Indicating Rotating Packer Setting Dog Sub
Product Family No. H26542
APPLICATION
The indicating rotating packer setting dog sub is similar to the standard dog sub above,
with two additional features that make it useful in all wellbores, including extendedreach. To provide visual confirmation that adequate setting force was applied to the
liner top packer, an adjustable shear indicator is included above the setting dogs. Also
incorporated is a tapered roller bearing assembly that allows rotation and slackoff of the
running string without damaging the packer extension or setting dogs. Rotation breaks
the static friction between the drillpipe and casing, reducing buckling and ensuring
adequate transfer of setting force to the liner top packer.

APPLICATION
An alternate configuration of the indicating rotating packer setting dog sub is available

packer extension one time without exposing the setting dogs. When stabbed back into
the extension, the setting dogs become armed, ready to expand the second time the
dog sub is pulled out of the extension.
Rotating Circulating Indicating Packer Setting Dog Sub
Product Family No. H26545
APPLICATION
The rotating circulating indicating, or RCI packer setting dog sub is a modified version
of the indicating rotating packer setting dog sub (product family no. H26542), and
is typically run in conjunction with an inner string. The tool includes a selective
circulating system that is activated upon setting the liner top packer. With the
indicating mechanism sheared, flow ports are opened between the ID of the running
string and the annulus above the packer. This allows circulation at the liner top to
remove excess cement, without the need to pull the inner string up to a circulating
position. The ports may be opened and closed repeatedly as required, and the running
string can be rotated during cleanup circulation if desired.

Delayed Opening Ball Seat
Product Family No. H27611
APPLICATION
The shearing out of conventional ball seats near the liner shoe is typically accompanied by some
degree of hydraulic surging. Certain formations may break down when this pressure wave exits the
shoe. This unintentional hydraulic fracture can lead to severe losses when the hydrostatic pressure
of the cement in the openhole annulus re-opens the fracture.
The pressure surge is caused by stored energy in the compressed fluid above the ball and seat. Baker
Hughes developed the delayed opening ball seat specifically to reduce the magnitude of the pressure
spike. The surge is reduced in two ways. First, the position of the ball seat in the wellbore reduces
the volume of compressed fluid significantly and allows the pressure wave to dissipate through the
volume of the liner before it exits the shoe. In this way, it provides the same benefit as the familiar
ST™ landing sub (product family no. H27605) and the extrudable ball seat (product family no. H27611).
The delayed opening ball seat offers an additional significant benefit toward reducing pressure
surging. Since the intensity of the induced surge is directly proportional to the compression of fluid
above the ball seat, it can be substantially reduced by bleeding back the applied surface pressure
after activating the ball seat release feature. Once the rupture disk bursts, hydraulic oil slowly bleeds
through an orifice and provides adequate time for the pressure to be reduced at surface before ball
seat extrusion. No appreciable pressure spike hits the formation.
Several innovative technologies are combined within the delayed opening ball seat, such as a supported
extrudable ball seat, precision rupture disk actuation, and controlled metering of hydraulic oil.

The shearing out of conventional ball seats near the liner shoe is typically

fracture can lead to severe losses when the hydrostatic pressure of the cement

Baker Hughes developed the delayed-opening ball seat (DOBS) specifically
to reduce the magnitude of the pressure spike. The surge is reduced in two

time for the pressure to be reduced at surface before ball seat extrusion. No
appreciable pressure spike hits the formation.
In additional to the above features, another innovative feature was added to the
next generation of the DOBS, which is called the uniball (UB) DOBS. Beneficial
when running with the ControlSet hangers, the UB DOBS allows applied
hydraulic pressure to consecutively set a hydraulic liner hanger and release a
hydraulic running tool in one actuation. This is accomplished by the use of an
isolating inner sleeve, which initially allows pressure to reach the hydraulic
hanger and then shifts, isolating the hanger and then allowing that pressure to
reach the hydraulic running tool.

ST Landing Sub
Product Family No. H27605
APPLICATION
The ST™ landing sub is installed in the running string below the setting
tool as a means of applying pressure to activate hydraulic devices. The
ST landing sub is especially useful in horizontal applications where it
may be difficult to seat a ball in a conventional Type II landing collar
near the shoe.
A setting ball is circulated to the ST landing sub, and applied pressure
will activate a hydraulic-set liner hanger and HR™ liner setting tool
(product family no. H26666), if used. After release of the setting tool
is confirmed, pressure is further increased to trip the ST landing sub to
the full open position. For most sizes, the setting ball will be expelled to
pass through the liner. Once the ST has been actuated, the tool allows
passage of the pump-down plug during cementing. The ST landing sub
can be used in combination with all conventional liner wiper plug and
LFC™ systems. Available with solid seat for float in liner applications.

Product Family No. H27606
APPLICATION
The Ported ST™ landing sub, similar in design to the standard ST landing
sub, is installed in the running string below the setting tool as a means
of applying pressure to activate hydraulic devices. The Ported ST also
includes upper and lower packoffs, and a ported section that closes
when the setting ball shears out. Typically run with an inner string, the
Ported ST allows actuation of a hydraulic-set hanger and/or setting tool,
and then restores pressure integrity of the running string after ball seat
shear-out.
The Ported ST is used for two main applications. During sequential
inflation of external casing packers, the inflation tool must be raised to
the position of each packer. An open port just below the liner setting
tool would not provide pressure integrity of the running string to
inflate the packers. Another common application is when it is desired
to displace the fluid in the liner to completion fluid immediately after
cementing. A full-length inner string is run, and circulation through the
inner string is possible since the port is shifted closed after actuation.
Available with solid seat for float in liner applications.

Conventional Liner Cementing Plug Systems
APPLICATION
Cementing plug systems used in liner applications typically serve two basic functions:
 They serve as physical barriers between the cement and other wellbore fluids as they are being
pumped, while effectively wiping the cement from the tubulars that it's pumped through.
 They confirm displacement volumes of both the running string and the liner. Visible pressure
indications signal when the cement has been completely displaced from both the drillpipe and the
liner casing.
Pump-Down Plug
Product Family No. H27020
APPLICATION
The pump-down plug, also referred to as the “drillpipe dart,” is used to wipe the running string
behind (and sometimes in front of) the cement. The pump-down plug may be used to latch into a liner
wiper plug as described below, or can be used to wipe both the running string and the liner casing in
small-diameter liner applications. Multiple darts may be used to more effectively wipe the tubulars
and reduce cement contamination. Various wiper fin, nose, and latch configurations are available to
fit a wide range of applications. Available in composite.
Pump-Down Plug
Product Family No. H27020
Type I Wiper Plug
Product Family No. H26921
APPLICATION
Liner wiper plugs are used to separate cement from the displacement fluid during cementing
operations. The Type I liner wiper plug is shear pinned to the bottom of the running string, below
the liner setting tool and packoff. At the tail of the cement, a pump-down plug (product family no.
H27020), is released and follows the cement down the running string. When the pump-down plug
lands in the liner wiper plug, pressure is increased and shears the liner wiper plug free, allowing both
plugs to be displaced as a unit to the landing collar. Both types of liner wiper plugs are manufactured
of drillable materials, and are rotationally locked into the landing collar to prevent spinning during
drillout. Ceramic seat available to prevent erosion at high circulation rates.

with spacers and mud as it is displaced. Similar to the LFC™ four-plug
cementing system, the slimhole plugs bound the cement, reducing
contamination. The slimhole landing collar and plug system is designed
for cementing small diameter liners, from 2-7/8 in. to 5 in.
The system consists of two pump-down plugs and a slimhole landing
collar. The lead pump-down plug is dropped in front of the cement,
and the follow plug dropped at the tail of cement. When the lead plug
reaches the slimhole landing collar, a rise in pressure allows verification
of displacement volume. An increase in pressure opens the bypass,
and displacement of cement continues. Finally the second plug bumps,
indicating the completion of the cement job.
The lead pump-down plug contains a rupture disk, which will burst and
allow displacement of cement to continue if the dart does not reach the
landing collar for any reason.

COMPdril Composite Lead/Follow
Plug System
Product Family No. H26944
APPLICATION
The COMPdril™ lead/follow plug system and COMPdril landing collar
(product family No. H27419) have been designed to increase the
reliability and performance of the current industry standard plugs while
reducing the shoe track drill-out time by using composite materials
instead of aluminum. In addition, the COMPdril system is designed to
maximize cement isolation from wellbore fluids, thereby decreasing
the amount of cement contamination. Several new features have been
incorporated into the new COMPdril lead/follow plug system setting
a higher standard for current plug systems on the market today. The
Liner Wiper plugs are securely attached to the COMPdril running tool
(product family No. H26944) with fully supported lock dogs rather
than simple shear screws preventing premature release. The plugs
incorporate multiple fins, similar to long string plugs that allow multiple
sizes of casing to be wiped. The bodies of the COMPdril plugs are
molded with a high strength composite material and designed so that
they can be drilled out easily, without compromising performance. The
releasing tool incorporates a safety device to ensure that the cement
job is displaced through the liner. In the event that the LWP does not
shear off, the pressure can be increased, and a rupture disk will blow.
This will allow fluid to bypass the plugs so displacement may continue.

LFC Four Plug System
Product Family No. H26927
APPLICATION
The LFC™ four-plug system consists of two unique liner wiper plugs and two pumpdown plugs. It is designed to isolate cement from wellbore fluids and minimize
contamination, or can be used in conjunction with an external casing packer and
pressure-actuated cementing (PAC) valve (product family no. H30112), for two-stage
liner cementing. The plugs are securely attached to the LFC adapter (product family
no. H26928), run below the setting tool, and held in place by fully supported collets
rather than simple shear screw attachment.
When used as a “lead-follow” cementing system, the first dart is released ahead of
the cement, is displaced down the running string, and lands in the “lead” liner wiper
plug. With pressure increase, the release mechanism of the lead plug activates
and the collet releases the lead plugs ahead of the cement. Behind the cement, the
second dart is dropped, and displaced to the “follow” liner wiper plug. The two sets
of plugs contain the cement in between, minimizing contamination of the slurry.
When the lead plugs reach the LFC landing collar, cement bypasses around the plugs
and out the shoe. At the end of cementing, the follow plugs latch into the landing
collar, providing a noticeable “bump” displacement pressure at the surface.
Two-stage cementing operations are similar, but plugs with modified nose profiles
and a single-plug LFC landing collar without bypass are used. The “lead” plugs are
pumped behind the first cement stage and are displaced through the PAC valve
to the landing collar above the shoe. The “follow” plugs are pumped behind the
second-stage and land in the PAC valve. An increase in bump pressure closes the
PAC valve and prevents u-tubing of second stage cement into the liner.

Composite Solo Plug
and Composite Landing Collar
Product Family Nos. H26941, H27420, and H26692
APPLICATION
Conventional liner wiper plugs are pumped behind the cement in order
to effectively wipe the liner of cement, and to provide a pressure
indication when the tail of the cement is at the landing collar. The new
composite solo plug and composite landing collar have been designed
to increase the reliability and performance of current industry standard
plugs, while easing the drillability of the shoe track. By incorporating
several new features, the composite solo plug sets a higher standard
for current plug systems on the market today. The plug incorporates
multiple fins, similar to long string plugs, that will allow multiple
sizes of casing to be wiped with the same plug and improve upon the
wiping ability of current plugs. The body of the solo plug is molded
with a high strength composite material and designed so that it can
be drilled out easily, without compromising the performance of the
current solo plug design.
The mechanism that releases the plug has been incorporated into
the solo liner wiper plug releasing tool (Product Family No. H26937).
The composite pump down plug (Product Family No. H27020) seats
and latches inside the composite solo plug. The composite solo
plug incorporates a nose seal that is compatible with our standard
type ( and type II composite landing collars. This allows the plug
to withstand 5,000 psi (336 bar) pressure differentials from above
(depending on the size). The running tool incorporates a safety device
to ensure that the cement job is displaced through the liner. In the
event that the composite solo plug does not shear off, the pressure
can be increased, and a rupture disk will blow. This will dump the
pressure to the annulus, therefore increasing the amount of area
exposed to pressure, and shearing a relieved section of the plug.
This will allow the pump down plug and composite solo plug to be
displaced to the landing collar.

Solo Plug
Product Family No. H26938
APPLICATION
The Solo Plug™ liner wiper plug system includes a number of
advancements designed to enhance reliability and performance over
conventional liner cementing plugs. The multiple fin arrangement,
similar to long-string casing plugs, will effectively wipe a wide range
of casing weights.
The plug is attached securely to the release adapter (product family no.
H26937) by a collet mechanism, which can only be released when a
dart is landed and differential pressure is applied. The plug cannot be
mechanically pulled off of the running string (for instance, while picking
up to confirm release of the liner setting tool) since it does not rely on
simple shear pin attachment. The release adapter includes a rupture
disk feature that provides a reliable backup releasing method if the Solo
Plug cannot be released at normal pump pressure.
Within the body of the Solo Plug is incorporated a ceramic pump-down
plug seat, to eliminate potential erosion at high circulation rates. The
Solo Plug and pump-down plug are designed to be compatible with
standard Type I and Type II landing collars, and will withstand high
differential pressures in both directions when the plug is latched. With
the nose seals landed, the plug's fins are not required to hold pressure
and- most importantly- the cement stays where you want it. Available in
composites 7 in. to 11-7/8 in.

Float Equipment
Cement-Filled Float Equipment
APPLICATION
Float collars and float shoes have long been considered standard equipment when running and cementing liner casing
strings. They perform the very important function of preventing the heavier uncured cement in the annulus from
u-tubing back into the liner when displacement is complete. Floats are basically one-way check valves. Components are
designed for easy drillout with all bit types, including PDC.
API Recommended Practices (RP) 10F specifies testing parameters and regimen for oilfield float equipment. RP 10F
includes two distinct types of testing. The first test qualifies the durability of the valves under high-rate, high-solids mud
flow, and the second test confirms the ability of the valve to hold differential pressure from below. The cement-filled float
equipment offered by Baker Hughes meets API RP 10F test specifications.
Single- and Double-Valve Float Collar
Product Family Nos. H10183 (Single Valve) and H10187 (Double Valve)
APPLICATION
Float collars are typically run one or two joints above the liner shoe and

EZReam Casing/Liner Shoe
Product Family No. H10087
APPLICATION
Heavy-duty EZReam™ technology is the robust casing/liner shoe. A durable
tungsten carbide and PDC cutting structure–an industry exclusive–enables
you to ream longer intervals through the most challenging hole sections. You
can even get to TD in a severely compromised borehole.
EZReam technology is drillable with a standard PDC or roller cone in onshore
and offshore applications. The unique, patented profile combined with the
material properties enables faster drillout than competitive designs.
With some reamer shoes, there is a risk of leaving an undrilled portion of
the nose downhole, which could damage the next bit or BHA. The EZReam
concave profile drills out from the center to the shoulder, eliminating this risk.
This is the industry’s only casing/liner shoe to offer a secondary bypass port,
which allows normal circulation or cementing to continue in the event of
nozzle plugging.
The 360° gauge coverage offers added stability and improves reaming
efficiency. The tool is undersized to promote a smooth transition of the liner
through the predrilled hole.

Tieback Seal Assemblies
Tieback Seal Assemblies
APPLICATION
Baker Hughes offers three standard types of seal assemblies for liner tieback completions. Seal assemblies are ordered to correspond
to the appropriate ID and length tieback extension that they will be stabbed into, and matched to the weight of the tieback liner. The
mandrel is often ported between the lower and middle seal stacks when the tieback is to be cemented. Several additional types,
including metal-to-metal seals, are available for the most demanding HP/HT and hostile environment applications. Optional o-ring
elastomers provide compatibility with most oilfield chemical environments.

Snap-In/Snap-Out Shear Release Anchor
Seal Assembly
Product Family No. H29753
APPLICATION
The snap-in/snap-out, set-down-activated, shear release anchor is an
anchoring and sealing device that connects the retrievable completion
string to the sealbore and thread of an “S” sleeve which is normally
run on top of the JMZX™ double-grip packer. Before committing to
full engagement of the anchor, the snap-in/snap-out function allows
accurate space-out of the completions string at surface in relation to a
tubing hanger.
The tool comprises a seal stack to maintain seal integrity from the
completion tubing/casing to annulus, a set-down sleeve to define
position of the latch within the anchor, and a lock ring to withstand
the forces induced when tension is applied via the tubing string. The
parting ring defines the value at which the tool will release from the “S”
sleeve and shear screws located in the anchor body, where the anchor
is activated to its fully operational state. As long as the predetermined
set-down is not exceeded, the tool will continue to have the ability to
snap in and snap out of the “S” sleeve without committing to its fully
locked-in tensile carrying condition.

APPLICATION
The pneumatic TD2 cementing system performs all of the functions of the standard TD2 system from
the safety of the rig floor, by using pneumatic actuators to replace manual operation. Cementing plugs
and setting balls may be dropped without the need for personnel to be raised into the derrick. Air valves
in the control panel can only be operated in a logical sequence, preventing the chance of accidental
dropping of the wrong plug or ball.
Conventional cementing systems require that rotation be stopped to launch balls and plugs. Resuming
rotation may be difficult or impossible after stopping the pipe. The pneumatic TD2 design permits
continued rotation of the liner at all times, enhancing safety and efficiency of the liner cementing
operation. The pneumatic system may be retrofitted to existing TD2 heads in district inventory.
