Smart Intervention
Smart Intervention Service–Closed-Loop Process Control
for Intervention Operations
Introduction
Many wellbore intervention operations, especially those that
get into difficulty, suffer from a lack of accurate information
about true downhole conditions. Actual downhole conditions
in deep, high-angle wells differ significantly from what is
indicated by traditional physical measurements taken at the
surface alone. The parameters measured downhole include
RPM, torque, tension, compression, stick-slip, bending
stress, dogleg severity, and many others.
Measurement-while-drilling (MWD) and sophisticated
drilling optimization technologies have substantially
improved drilling performance and reduced non-productive
time (NPT). Baker Hughes is now bringing the advantages
of drilling optimization, real-time downhole measurements,
and closed-loop process control to intervention operations
with its SMART™ Intervention service.
SENTIO Tool: The Enabler
The enabling technology for SMART Intervention service is
the SENTIO™ Tool, a downhole data acquisition tool based
on drilling optimization technology developed by
Baker Hughes. The SENTIO tool contains an array of sensors
that sample critical static measurements. After the data is
digitized, a digital signal processor (DSP) in the tool analyzes
all data streams simultaneously at a high data rate and
outputs static measurements and computed diagnostics.
The outputs are prioritized into the most suitable jobspecific data sequence and transmitted to a rig-floor display
screen (and, if desired, to a remote real-time operations
center), where they are presented in the clearest and most
meaningful manner. Portions of the information can also be
recorded and stored in the on-board memory, then retrieved
later at surface for detailed evaluation.
SMART Intervention systems acquire critical downhole data
and transmit it to surface to provide valuable information on
intervention parameters that have never before been seen
at surface and give well teams a better understanding of
what is happening at the business end of an intervention
bottomhole assembly (BHA). Armed with this knowledge,
well teams can make informed, just-in-time decisions that
can optimize well intervention operations, significantly
reducing NPT and risk exposure.

APPLICATION
Using the SMART™ Intervention service, well teams have avoided NPT by:
„„Using
knowledge of slight increase in downhole weight to prepare a subsequent operation before the lightweight fish
was out of the hole
„„Measuring Vectored Annulus Cleaning System (VACS) chamber filling progress and allowing progress to be observed at
surface in real-time
„„Using downhole force-on-tool data to verify that workstring stiffening would prevent buckling during packer manipulation
„„Continually monitoring window quality and optimizing torque, RPM, WOB, and ROP in a critical, deep casing exit
„„Increasing rotation by a measured amount to eliminate stick-slip in a reaming-while-milling application
Advantages
(For Field Operators)
„„Reduce risk and NPT
„„Reduce operating costs
„„Optimize intervention operations
(For Intervention Field Engineers)
„„Complement sense of feel while working the string at surface
„„Help deliver optimal intervention performance
„„Accelerate learning curves for new tool service operators (TST) with limited

Smart Intervention
SENTIO
Product Family No. H13500
APPLICATION
The Baker Hughes SENTIO™ tool provides advanced SMART Intervention™ data acquisition and
diagnosis technology for all of the Baker Hughes downhole tool configurations.
The SENTIO tool features a total of 14 well intervention process sensors in a dedicated sub. All
sensors are simultaneously sampled at a high data rate of 1,000 Hz. A highly efficient Digital Signal
Processor (DSP) in the tool continuously monitors the data stream and diagnoses the occurrence and
severity of vibration related problems such as BHA whirl, stick-slip, mill bounce, etc. The dynamic
diagnostics are transmitted to the surface via mud-pulse telemetry along with static tool data such
as downhole weight overpull, torque, bending moment, and annulus pressure. In addition, the tool
offers the unique capability of storing high frequency data onboard. The data can be retrieved later at
surface for detailed evaluation.
The transmitted SENTIO diagnostics and data are displayed on a real-time rig floor display alongside
surface data. This real-time feedback about the downhole environment provides the tool service
technician (TST) with a new level of intervention process control. Immediate remedial actions can
be taken in case of problems by changing job parameters and, more importantly, safely optimize the
entire well intervention process.
Advantages
„„Immediate
detection and resolution of
• Dynamics related problems
• Weight transfer problems
• Milling hydraulics problems
„„Enhanced ROP and optimized intervention process
„„Local dogleg-severity monitoring and control
„„Improved casing exit window quality
„„Longer mill life

Internal/External Cutter Tools
APPLICATION
Internal/external cutter tools are used in a wide variety of fishing
applications. Baker Hughes offers internal cutters for multi-string
cutting of casing associated with well abandonment, down to
single-string cutters used for production tubing. Internal cutters
are normally run with stabilizers to improve cutting time. External
cutters are generally used when the ID of the tubing or
small casing has become plugged. The external cutters are run on
the bottom of washpipe, allowing for cutting and recovery in one
run. It is recommended that the external cutter be run only if the
fish is known to be free or has been washed over in the previous
trip. However, the BG™ cutter can be rotated while washing over
the fish.

Multi-String Cutter
Product Family No. H17008
APPLICATION
Multi-string cutters are used to cut through
multiple strings of casing or large-diameter
strings, quickly, and safely. Multi-string cutters
are used on both fixed and floating platforms as
well as on land rigs.
and/or below. When cutting depth is reached,
rotation begins. Pump pressure is applied to force
the knives against the casing ID. Rotary speed and
pump pressure are then increased until the knives
have cut through the casing and expanded to their
maximum position. A sudden pressure drop and
torque decrease indicates the cut has been made.
After finishing the cut, the pumps are shut off and
the tool is pulled out of the hole.
Operation
The multi-string cutter is hydraulically operated by
drilling fluid flowing through an indicator nozzle
and activating a piston, which contacts the cutter
knives and pivots them into cutting position.
Note: For floating platform operations, a slack
joint or motion compensator, marine swivel, and
space-out assembly are required in addition to
the stabilizers.
The cutter is dressed with proper knives and run
in the well with a stabilizer immediately above

Hercules Multi-String Cutter
Product Family No. H17009
APPLICATION
The HERCULES™ multi-string cutter is a hydraulically operated solid-body tool
used to cut through multiple strings of casing or large-diameter strings, quickly
and safely. The HERCULES multi-string cutter’s three knives are 30 percent
stronger than the standard multi-string cutter. The knives are normally dressed
with either SUPERLOY™ or METAL MUNCHER™ inserts.
The HERCULES multi-string cutter can be used in any cutting application where
rotation and pressure can be applied to the tool.
Operation
The HERCULES multi-string cutter is hydraulically operated by drilling fluid
pressure acting against a piston. The necessary pressure differential is
established by the flow rate of the drilling or workover fluid through the indicator
nozzle. The nozzle size can be adjusted as necessary to produce a sufficient
pressure differential depending on the fluid pump flow rate available. Standard
bit nozzle sizes are used for convenient interchangeability. At sufficient pressure
differential, the piston will move against the compression spring and contact
the knife heel, moving the knives into cutting position. The continued movement
of the piston forces the knives to pivot about the knife pins. When the knives
are near full extension, the indicator contacts the indicator stop. At this point,
drilling fluid begins to flow freely through the indicator, which results in a
sudden pressure drop, signaling the operator that the knives have come to a
fully extended position. In subsea applications, a marine swivel or universal
wellhead recovery system is required. When performing casing repair operations
for a slot recovery, safeguards must be taken to ensure the outer casing is not
damaged. For this type operation, the HERCULES multi-string cutter can also
be mechanically controlled by the positive adjustment screw, which is installed
below the knives, limiting the maximum knife extension.

Inside Mechanical Casing Cutter
Product Family No. H17012
APPLICATION
Inside mechanical casing cutters are used to cut tubing and casing internally. Each cutter
consists of a friction assembly used to set the tool in the pipe, a slip assembly for anchoring
and a cutting assembly with tool steel or insert knives. The tools cut quickly and easily convert
to alternate casing weights.
The inside mechanical casing cutter is lowered into the hole to the point where the cut is to
be made. The tool is rotated to the right and gradually lowered. This action allows the friction
block assembly to unscrew from the mandrel, which anchors the tool in the pipe. Once the
slips are set, the wedge block forces the knives outward until the pipe is cut. When the cut is
complete, picking up the workstring; automatically returns the friction assembly to the run-in
position. An automatic nut design allows the tool to disengage and reset repeatedly without
coming out of the hole.
Advantages
„„Each
tool easily converts to cut alternate casing weights
„„Automatic nut design allows the tool to disengage and reset repeatedly
without coming out of the hole for multiple cuts
„„Tool is mechanically operated; no hydraulics are required
„„Slip assembly centrally anchors the cutter to ensure a precise, smooth cut
„„Body constructed from AISI 4140 heat-treated alloy steel
„„Knives are made of tool steel or inserts

Inside Hydraulic Cutter
Product Family No. H17003
APPLICATION
The inside hydraulic cutter cuts single strings of casing hydraulically. The cutter features
hydraulically activated knives for smooth, efficient cutting; an indicator which signals through
pump pressure when the cut is complete; and stabilizer slips to keep the cutter anchored in
the casing. The pistons force the slips to firmly anchor the tool prior to the knives contacting
the casing.
When the cutter has been run to the desired cutting depth, rotation is initiated and circulation
started. An increase in torque indicates that casing is being cut. When the cut is complete,
the control dog will move into a recess in the bottom nut, causing a decrease in pump
pressure, indicating that the cut is complete. Straight pick-up will retract the slips and knives.
The inside hydraulic cutter should always be run with a float sub.

BG Outside Cutter
Product Family No. H17017
APPLICATION
The BG™ outside cutter is an automatic, springfed cutter that provides fast and reliable external
cutting and recovery of tubing and drillpipe. The
cutter applies a predetermined and controlled
amount of pressure on the knives, eliminating
the problem of broken knives and missed cuts.
This automatic feature compensates for any
miscalculations or faulty readings regarding the
amount of strain pulled on the fish, eliminating knife
breakage. This feature makes it ideal for high-angle
and horizontal wells. The pipe latching assembly
can be furnished to catch under the couplings or
collars of square-shouldered pipe and under the
upset of integral joint pipe. The ability to adjust the
amount of force on the knives allows pipe of varying
degrees of hardness to be cut quickly and reliably.
The cutter is excellent for cutting tubing with coiled
or smaller tubing inside.
Operation
Prior to running in hole, check to see that the cutter
is properly dressed for the size pipe to be cut. Make
up cutter with optional shoe on bottom. Also, in a
very high angle hole, it is recommended to run a
shoe with the smallest ID as possible and, also, run
an extension or joint of washpipe below cutter to
help stabilize the cutter. Run enough washpipe to
cover the fish. Once over the top of the fish, take
care in elevating the workstring until the cutter is
at the desired depth where the cut is to be made.
Pick up and pull against the tubing collar or upset,
5,000 lb (2 268 kg) minimum to make sure you are at
a collar or tool joint. Rotate pipe at 20–40 RPM. It
is recommended to cut with workstring weight plus
weight of fish to be cut. Do not pull more than the
limit of the flipper dogs. Once the cut is complete,
the cutter and fish can be pulled out of hole and the
fish stripped out of the washpipe. The cut left by the
outside cutter will be smooth on the OD and just
slightly flared to the ID. To engage externally and
run wireline would require no dressing off.
Advantages
„„Eliminates
as many parts and failure points as possible
„„Cuts various grades of pipe hardness and tool joint configurations
„„Assures a cut even if the strain pulled on pipe was above or below desired amount
„„Cuts tubing with coiled tubing inside and recovers both strings
„„Normally cuts pipe in less than five minutes, compared to 1/2–2 hours of rotation previously
„„Large ID allows cutter to pass over gas lift mandrels, ball valves, etc.
„„Eliminates knife breakage when swallowing fish
„„Use in horizontal outside cutting applications
„„Can rotate while washing over fish

depth. Once reaching the desired cutting depth the
string should be elevated to locate a collar or tool
joint. The string is then lowered to take any load
off the knives before cutting.
Operation
Once the cut is complete, the cutter and fish can
be pulled out of hole and the fish stripped out of
the washpipe. The cut left by the outside cutter
will be smooth on the OD and slightly flared on the
ID. To engage externally and run wireline would
require no dressing off.
The tool is operated by pulling the dog assembly
up under a collar or tool joint while rotating. The
dog assembly will force the wedge block down,
which forces the knives in until the cut is complete.
It is recommended to wash over with a rotary shoe
and washpipe before running the cutter. Once
the fish has been washed over, the rotary shoe
is replaced with the cutter. After the cutter has
passed over the fish, the workstring should not be

Internal/External Engagement Tools
APPLICATION
The preferred method of engaging a fish is to screw in with
drillpipe. When this is not possible, internal and external
engagement tools provide an alternate means of reconnecting
to the fish. Preferably, engagement tools will have a releasing
mechanism, allow circulation to the fish and provide an
unobstructed ID to allow for wireline operations. An overshot
is normally the first choice when screwing into the fish is not
possible. If the fish cannot be externally engaged, a releasable
spear (or internal engagement device) should be used to retrieve
the fish. Non-releasable tools such as box taps and pin taps
should only be used as a last resort or when the fish top is badly
damaged or unknown. All engagement tools are run with bumper
jars to assist with engagement and disengagement of the fish.
Non-releasable devices should always be run with a safety joint to
provide an emergency disconnect in case the fish will not pull free.

The Series 150 Bowen Releasing and Circulating Overshot
APPLICATION
The Series 150 Bowen™ releasing and circulating overshot is the strongest tool available to externally
engage, pack off, and pull a fish. The tool's basic simplicity and rugged construction have made it the
standard of all external catch fishing tools.
The Series 150 Bowen releasing and circulating overshot is composed of three outside parts: top
sub, bowl, and guide. The basic overshot may be dressed with either of two sets of internal parts,
depending on whether the fish to be caught is near maximum size for the particular overshot.
Some special conditions apply. If the fish diameter is near the maximum catch of the overshot, a spiral
grapple, spiral grapple control and Type A™ packer are used. If the fish diameter is considerably below
maximum catch size (usually 1/2 in. [12.7 mm]), a basket grapple and a basket grapple mill control
packer are used.

High-Pressure Packoff Assembly
Product Family No. H11059
APPLICATION
The high-pressure packoff assembly is an overshot accessory that is used to establish high-pressure
circulation down the well or for tubing patch applications. The packoff is a simple design consisting of
the packoff sub with packing and packing retainer rings.
Operation
The high-pressure packoff is run between the top sub and the bowl. Once a clean fish top has been
established, the high pressure packoff can be run with the overshot. The fish is engaged following
the operation instructions for the overshot. Once the fish has been positively engaged, it is possible
to apply two to three times the pressure that can normally be applied to a standard overshot packing.
The packing is normally stacked to hold pressure internally and externally.
Advantages
„„Converts
standard overshot to a temporary or permanent tubing patch
high-pressure circulation to the fish to remove ID blockage and spot releasing fluid
„„Packing is corrosion-resistant to downhole fluids; H2S service assemblies are available by
special request
„„High-pressure packoffs withstand two to three times the pressure for which standard
overshot packing is rated

Kelo Socket Overshot
Product Family No. H11006
Application
The kelo socket overshots are simple bulldog overshots used to catch small-diameter workstrings and
sucker rods inside casing. They are also used to recover coiled tubing that has parted and remains in
the hole.
Operation
Before running, the kelo socket is dressed with the correct slip. The tools are tripped in the hole and
the kelo socket is lowered over the top of the fish without rotation. If the fish has a flared top, it is
dressed off with the SUPERLOY™ dressed guide using right-hand rotation. The rotary is then stopped
and the kelo socket is lowered over the fish.
The slip is engaged by picking up on the workstring. The slip, which is pushed up the slip guide,
catches the OD of the fish and starts down the slip guide’s tapered slot. The more pull, the tighter the
slip will grip the fish.
Note: This overshot is not releasable after the slip is engaged.
Advantages
„„Slip
is the only moving part
„„Slip rides in a T-slot in the tool and opens and sets without rotation
„„Optional oversize guides available to prevent overshot from missing fish when
washing over

T-Dog, Mouse-Trap, and Flipper-Dog Overshot
Product Family No. H11407
Application
The t-dog, mouse-trap, and flipper-dog (TMF) overshot is an overshot that
can be dressed three different ways for different applications. It is threaded
on both ends so that it may be run anywhere in a washover string. There
are no windows in the body of the tool, therefore it may be used in full
washover applications.
The t-dog slips are used to catch square-shouldered collared pipe. The
t-dog overshot is used to washover and recover mud stuck or sanded up
collared pipe in one-trip when the entire fish can be washed over. This type
is releasable.
Flipper-Dog
Cage Assembly
The mouse-trap assembly is used to catch sucker rod or integral joint tubing.
The mouse-trap overshot is effective at fishing cable, coiled tubing, and
sucker rods. Depending on the application, the flapper may be manufactured
with cutting or gripping capabilities. When used for this application, the
overshot is not releasable.
T-Dog Cage Assembly
The flipper-dog assembly is used to catch integral joint tubing or a fish with
different ODs. The flipper-dog overshot can be used to washover mud stuck,
sanded up collared or integral joint pipe. When used for this application, the
overshot is not releasable.
Advantages
body with no windows allows the overshot to be used in
the washover string for one-trip recovery
„„Cage design allows unrestricted passage of coupling through
the tool and let's the operator wash over several joints of pipe
„„Dogs and slips are energized by springs that place them in the

Hydraulic Casing Spear
Product Family No. H12309
Application
The hydraulic casing spear is run above a mechanical or hydraulic inside
casing cutter and used to retrieve casing sizes from 9-5/8 in.–13-3/8 in.
(244.5 mm–339.7 mm). This application allows cutting and pulling the casing
string in one trip. The spear can be rotated inside the casing string without
engaging. Once the cut is completed, the spear can then be positioned at the
desired location inside the casing string. The rugged design of the spear makes
it well suited to withstand the most severe downhole environments for retrieval
of casing.
Operation
Dress spear to the correct size casing to be engaged. It is recommended to run
the hydraulic spear one joint above the cutter you are using. This will prevent
having to strip out of the casing at surface to lay down cutter and accessories.
Once cut has been made, pick up to position the spear at the top of casing
string. Drop restriction plug in drillpipe. Allow one minute per 1,000 ft (305 m) for
restriction plug to seat in spear. Pressure up slowly to the necessary pressure
drop (minimum of 500 psi [34.47 bar]) to set spear. Once the spear is set, pick
up, and pull on casing. Pull out of hole slowly. Set the joint of pipe on top of
the spear in rotary and drop shear release ball in pipe. Pick up kelly or top drive
and screw into same. Pick up and set casing in slips and secure. Pressure up
on spear to the necessary shear load. Once shear screws are sheared, spear is
released and can now be laid down.
Advantages
„„Allows
cutting and retrieval in one trip
construction, easy operation and maintenance
„„Bore-through ID of tool permits circulation to casing cutter
„„Slips are retracted inside of body to prevent damage to tool or
casing when casing is being cut downhole

Type B Casing and Tubing Spear
Product Family No. H12609
Application
The Type B™ casing and tubing spears are used to retrieve casing
sizes from 4-1/2 in.–13-3/8 in. (114.3 mm–339.7 mm). The design of
the spear makes it the easiest spear on the market to release. The
spear can be set for right-hand or left-hand release and is easily
field-dressed to change the release setting.
Operation
To engage the spear, it is lowered into the fish until the slips are past
the top of the casing. One-quarter rotation will place the spear in
the catch position. Due to the slotted mandrel design, the spear can
be released with only enough downward travel to break the freeze
between the slip segments and the mandrel. Once the freeze is
broken, rotate one-quarter round in the release direction, releasing
the spear. The spear design will protect the slips when running down
inside the fish and may be run to any depth. This feature makes the
Type B perfect for setting underwater casing patches.

Product Family No. H12009
Application
The Type D™ casing and tubing spears is used to retrieve all casing sizes
from 4-1/2 in.–30 in. (114.3 mm–762 mm). It is ideal for backing off casing
or rotating out mudline hangers and packer bore receptacles. The spear
can be set for right-hand or left-hand release and is easily field-dressed to
change the release setting. The J-Slot, which holds the spear in the catch or
release position, makes this spear the most reliable for the recovery of small,
lightweight fish.
To engage the spear, it is lowered into the fish until the stop ring is taking
weight. One-quarter rotation will place the spear in the catch position. The
spear is released by bumping down and then applying one-quarter rotation in
the opposite direction. Because the mandrel must travel down the body length
of the J-Slot to release, the stop ring should not be removed from the body.

Type E Casing Spear
Product Family No. H12109
Application
The Type E™ casing spears enter and engage
casing so it can be pulled from the hole. These
casing spears, designed to withstand the most
severe downhole requirements, are available
in two sizes. The smaller-size handle
7 in.–11-3/4 in. (177.8 mm–298.5 mm) casing
and the larger size handle casing that is
13-3/8 in.–30 in. (339.7 mm–762.0 mm).
Operation
The tool is normally run into the hole while in
the catch position. Drill collars and jars are run
when a stuck fish is anticipated.
The Type E casing spear may be operated in
two modes: with a stop ring (i.e., when the top
of the casing is fairly uniform and the OD of
the tool is unrestricted); or, without a stop ring
(i.e., in split casing or to set the spear deep
within the casing).
Caution: When running this spear without a
stop, the friction between the spear slips and
casing wall must be great enough to release
the slips.
When tripping in, the spear is carefully
lowered as it approaches the fish until it is
fully inserted into the fish. The spear is then
lowered several feet into the fish to avoid
splitting the casing and to assure a firm grip for
pulling. If a stop ring is used, sufficient weight
must be applied to ensure that the spear stop
rests on the casing. Picking up on the string
then forces the slips outward from the slip
cone to engage the pipe.
The spear can be released at any time by
sharply dropping the string to break the
contact between the slips and mandrel, then
rotating one-half turn to the right. The spear
can be reset to the catch position by rotating
one-half turn to the left. The spear can be set
and released repeatedly without coming out of
the hole.
Advantages
„„Heavy-duty,
high-strength design withstands the most severe downhole requirements

„„Full-bore ID through tool
„„Smaller size may be run with an alternate slip retainer nut with stop to indicate
proper depth within the fish

Spear Packoff
Product Family No. H12115
Application
The spear packoff is run just below a casing
spear to pack off and allow hydraulic pressure
to be applied to the fish. Applying this pressure
dramatically improves the lifting power of the
fishing string and helps break down sediment
or formation by forcing circulation through and
around the fish.
Once the packoff is inside the casing, spear
operation continues. The pump is turned on
if the casing needs to be pressurized or
circulation established.
Operation
Caution: Special care should be taken when
entering the casing stub not to damage the
packing element, particularly when the casing
top has been damaged and has burrs or jagged
edges that will cut the element.
The spear packoff is made up to the lower pin
connection of a casing spear when fishing for
casing. The tool is guided into the casing by a
special guide positioned just below the
packing element.
Specifications
The spear packoff is available in casing sizes
from 4-1/2 in.–20 in. (114.3 mm–508.0 mm).
Advantages

Taper Tap
Product Family No. H12100
Application
Taper taps engage the inside of a fish where conventional releasing spears would not be
feasible. Like the box tap, the taper tap is designed to cut threads where no threads are
present. Taper taps can be used to fish tubulars, bridge plugs, packers, or other types of
downhole equipment.
Operation
Run the taper tap into the hole and lightly tag the top of the fish. Pick up and begin to
rotate slowly. Note the free torque of the workstring. While rotating, slowly lower the
taper tap into the fish until the torque begins to build up rapidly. Increase the set-down
weight as the torque increases. Once the taper tap is firmly seated in the fish, attempt to
retrieve the fish with straight pull (dependent upon the fishing scenario).
Caution: Taps are nonreleasable and should be run with bumper jars and safety joints.
Taps should only be used when releasable engagement-type tools are not an option.

Hollow Pin Tap
Product Family No. H12101
APPLICATION
The hollow pin tap is designed for a very specific operation. When a joint
of washpipe has twisted off with a fish sticking out of the top, a hollow pin
tap is usually the only solution. Hollow pin taps are manufactured with any
connection. The taps have the same ID as the washpipe connections. This
allows washpipe that has twisted off over the maximum washover size to
be engaged.
Operation
Run the hollow pin tap into the hole and lightly tag the top of the fish. Use
caution going over the fish sticking out of the top of the washpipe. Pick up
and begin to rotate slowly. Note the free torque of the workstring. While
rotating, slowly lower the hollow pin tap into the fish until the torque
begins to build up rapidly. Increase the set-down weight as the torque

Mills and Shoes
Mills and Shoes
Application
Mills and shoes remove metal, cement, or other debris
lodged in the wellbore. Mills come in a wide variety
of types and are generally used when the full ID of
the tubular needs to be cleaned. Applications include
milling tight spots, cement, tubing, packers, bridge
plugs, and other debris. Boot baskets are run above the
mills to collect larger pieces of debris. Rotary shoes are
generally run with washpipe in applications where only
the material between the tubular being washed over and
the ID of the casing or formation needs to be removed.
Applications include but are not limited to sanded-up
tubing and openhole where the formation has fallen in.
Washover shoes are also used to mill over packers. This
allows for minimum material removal in order to free the
packer. With both mills and shoes, it is recommended to
run jars and drill collars to help prevent sticking.

METAL MUNCHER Junk Mill
Product Family No. H15102
application
The METAL MUNCHER™ junk mill is used for milling stationary obstructions. The junk
mill uses the patented METAL MUNCHER technology as the lead cutting structure while
being backed up by SUPERLOY™ tungsten carbide. With the SUPERLOY backing, if the
METAL MUNCHER inserts become damaged, the mill will perform like a standard junk
mill until a new row of inserts are exposed.
The mills have been used to mill cemented tubing, in some cases at rates exceeding
30 ft per hour (9 m/hr). Cemented drill collars and drillpipe have in many cases been
milled faster than they could be washed over and recovered.

Taper Mill
Product Family Nos. H15110
application
Taper mills enter restricted areas in casing, tubing or openhole and remove restrictions or
obstructions by milling.
Taper mill designs vary, based on the intended use. Taper mills designed for uses inside
casing are dressed with SUPERLOY from the reduced OD at the bottom of the mill to the
full drift of the casing. Once full-drift OD is reached, the taper mill will have a length of
smooth, turned-down SUPERLOY for stabilization, minimizing any unnecessary casing
damage. For openhole applications, the rough SUPERLOY cutting structure extends over
the entire dressed area of the mill.
When run with a section mill or pilot mill, the taper mill acts as a stabilizer, reducing
vibration, and increasing section mill life. The taper mill also acts as a guide when
entering the casing.

The string and watermelon mills elongate casing windows during
a whipstock operation. They can also be used to remove tight
spots, restrictions, or dog legs in casing. These types of mills are
often run above section mills so any bird nesting of cuttings can
be broken up and circulated to ensure that the section mill can be
pulled out of the well. Most of the mills have a standard drillpipe
or drill collar connection to eliminate crossovers.

Hollow Mill Container and Insert
Product Family Nos. H11024, H11246 and H15120
Application
The hollow mill assembly, which consists of a hollow mill extension and a hollow mill insert, is used
as an overshot accessory to mill away flared or oversized tops of pipe that have been jet cut or broken
off during drilling or workover operations. The hollow mill assembly makes it possible to mill over and
recover fish in a single trip.
Operation
The hollow mill assembly is installed between the overshot bowl and guide. Due to the total torque
being applied to the tang of the hollow mill insert, the milling operation should be carried out with
low weight and torque. Once the oversized fish top is milled away, the overshot can be lowered to
engage the fish with the basket grapple.
Advantages
„„Permits
milling and recovery in a single trip
design of insert permits full removal of flared or oversized fish top
„„Mill insert placement allows the fish to be dressed before the grapple engages
and gives the operator positive indication that the overshot will swallow the fish

and Applications
METAL MUNCHER
Application
In 1985, Tri-State Oil Tools (now part of Baker Hughes) changed the fishing industry
forever with the introduction of the METAL MUNCHER™ carbide insert. This insert and
its patented application for milling tools has increased penetration rates and mill life
by as much as 1000%. METAL MUNCHER buttons, as they are referred to, are made
by pressing tungsten carbide powder into a mold and heating them in a furnace. The
design of the button allows downhole milling similar to what is done using a machine
shop lathe. Available in .375-in. (9.5-mm) and .25-in. (6.35-mm) sizes.
METAL MUNCHER cutting structures are used primarily on window mills, section
mills, and pilot mills. With the controlled cutting angle and chip-breaking features,
these mills can be effective on high-chrome content steels and are engineered to cut
the metal away instead of grinding it. METAL MUNCHER mills produce small, uniform
cuttings that eliminate bird nesting and make it easier to circulate the cuttings out of
the well. By using METAL MUNCHER technology, the weight on mill required can be
significantly reduced.
METAL MUNCHER
Opti-Cut
Application
A new cutting insert from Fishing services is now available. Preliminary testing has
shown very favorable results. The cutters are an improvement over the traditional
SUPERLOY™ randomly crushed carbide cutters now in use. In some very specialized
applications, they may also be used in place of the METAL MUNCHER insert. The cutters
are designed to act much like SUPERLOY, but are no longer randomly shaped. Each piece
has identical geometry optimized so that no matter how the cutter is placed on the body
of the cutting or milling tool, there is always a sharp cutting edge and/or point looking
up. As the cutter is worn down, new cutting edges and points are exposed. The new
cutter has a total of sixteen cutting points and eight cutting edges. Applications range
from thru-tubing fishing, packer milling, washover shoes, casing/tubular cutting and
milling anywhere extremely sharp cutting edges are desirable. Opti-Cut™ is available in
rods similar to the SUPERLOY rods. They are applied using the same heat guidelines as
SUPERLOY. The individual inserts are laid randomly.
Opti-Cut
Advantages
„„Optimum-shaped
geometry assures sharp cutting edges and points are looking
up no matter how the insert is positioned
„„Sixteen cutting points and eight cutting edges
„„Sharp edges and points result in less weight and increased rate of penetration
„„Rod form for easy application
„„Increased surface area for improved bonding to base metal
„„Dual concave ends for maximum exposure of cutting points
„„Smaller cuttings easier to circulate out of the hole

Application
This material is made of crushed sintered-tungsten particles that are suspended in
a special copper-base, brazing-type alloy with high nickel content. Tungsten carbide
is the finest milling material available for downhole steel cutting or milling tools.
SUPERLOY™ is used for all types of downhole cutting and milling. We provide junk
mills of all types and sizes, rotary shoes for all sizes and tapered and string mills of
various ODs. SUPERLOY works well on milling loose junk such as bit cones, tong
dies, packers, and for washing over stuck or cemented pipe. SUPERLOY can be
used to dress off the OD or ID of casing to provide for a clean top for casing patch
operations. SUPERLOY is used on the upper and lower watermelon mills for the
WindowMaster™ system.

are milled with a packer shoe that has an ID 1/16 in.
bigger than the OD of the mandrel and an OD at casing
drift. After milling down to the top slips, the packer can
usually be pulled from the well. For retrievable packers
that will not release, it is recommended to run a shoe
with a large ID and an OD at drift. With retrievable
packers, it is normal to mill down to the top slips before
the packer can be pulled. There are two categories of
packer recovery tools; one type engages the top of the
packer and the other engages the bottom. Itco spears
and taps engage the top of the packer. Mechanical or
hydraulic packer and retrieving tool (PRT) run below the
packer into the millout extension and engage the packer
from the bottom. Boot baskets and jars are recommended
in all packer milling and recovery operations.

Quick Pick Packer Milling System
Product Family No. H14028
Application
The quick pick packer milling system is designed for milling packers in the shortest possible
time and retrieving them in one trip. The system contains a mill that uses the patented
METAL MUNCHER™ technology as the lead cutting structure backed by SUPERLOY™. With
SUPERLOY backing, if the METAL MUNCHER inserts become damaged, the mill will perform
like a standard packer mill until a new row of inserts is reached. The aggressive cutting
structure of the inserts can be effective in milling high-chrome, harsh-environment packers.
The system also contains a new, innovative packer retriever that is directly connected to the
packer mill. This system allows engagement of packers with a seal bore or a smooth ID. It
allows for constant rotation while remaining in the engaged position to prevent the packer
from falling when it breaks loose. It can be engaged and released multiple times.
Operation
Choose the correct milling head and retrieving tool for the job. The OD should be equal to
the drift ID of the casing size and weight you will be working in. Make up packer retrieving
mandrel to top sub, makeup top sub/mandrel to milling head, slide bearing assembly with
grapple up on the mandrel and make up nut. Make sure in the milling position that the top of
the grapple is no more than 4 in. (101.6 mm) below the bottom of the mill head.
Running procedures for this tool are to pick up tool, run in hole, locate the top of the packer,
stop rotation, and enter the packer bore. As the retrieving tool enters the bore, the grapple and
the grapple carrier will slide up to the shoulder on the mandrel. The upward movement occurs
because the grapple OD is larger than the ID being engaged. Additional downward force will
compress the grapple to enter the bore. Lower the entire assembly until the mill contacts the
top of the packer (slight overpull can be performed to ensure that grapple is in catch position).
Again, lower string until mill sets on top of packer—pick up and begin milling. At any point in
the milling process, the grapple can be released by stopping rotation, setting down load, and
lifting as lightly as possible while rotating slowly to the right.

Mechanical Packer Retrieving Tool
Product Family No. H14031
Application
The mechanical packer retrieving tool (PRT) removes drillable packers from the wellbore.
It is used as the retrieving mechanism of a packer milling-retrieving assembly. The PRT
passes through the bore of the packer and engages the lower end of the packer to allow
a one-trip milling and recovery operation.
Operation
The PRT is installed at the lower end of the milling assembly by means of extension
joints. This allows the spear to clear the lower end of the packer bore before the packer
milling shoe or mill makes contact with the outside of the packer. When the spear enters
the packer bore, the retrieving slip is forced up into a position where the OD is reduced
to allow passage through the packer bore. As the slip clears the lower end of the packer,
it drops into the catch position. The milling operation may now be performed and the
packer retrieved. The spear will remain in the catch position and withstand severe
upward strain and sudden movement of the packer. If necessary, the retrieving spear may
be released from the packer bore by right-hand rotation and lowering of the fishing string
after the spear slip has been pulled into friction contact with the packer bore.
Advantages

Product Family No. H14136
Application
The shear pin type PRT is a combination mill and spear designed to recover drillable
packers in a one-trip milling and recovery operation.
Operation
Prior to running the tool, it is important to ensure that: 1) the proper grapple has been
installed; 2) sufficient lengths of PRT extension joints have been added; and 3) the correct
number of shear pins have been installed in the spear mandrel and grapple. As the spear
enters the packer bore, the grapple shear set screws shear, giving a positive indication
of entry into the packer. The grapple remains in the catch position during the milling
operation. If it is necessary to release the spear from the packer, the workstring is picked
up to the load that has been predetermined to shear the pins in the spear mandrel.

Hydraulic Packer Retrieving Tool
Product Family No. H14066
Application
The hydraulic packer retrieving tool (PRT) provides a reliable method of milling and retrieving
permanent packers in one run. This tool provides two methods to release from the packer downhole.
Operation
The primary release is activated by increasing the flow rate through the tool forcing the grapple up
the PRT mandrel into the release position. The increased circulation rate is maintained until the PRT
spear has been pulled through the packer bore. This method has proven to be very desirable in highly
deviated holes where the activation of J-Slots or straight over-pull shearing can be difficult.
The secondary method of releasing is accomplished by shearing the emergency shear ring. Normal
shear ring values range from 200,000–500,000 lb (90719–226796 kg) of overpull. Hydraulic jars should
be run to apply the high shearing force required at the tool.
Advantages

Type B Packer Retrieving Tool
Product Family No. H14132
Application
The Type B™ packer retrieving tool (PRT) is used to burn over and retrieve in one trip
packers without millout extensions, cement retainers, and bridge plugs. The tool is
used with a releasable engaging device. The tool is also used to retrieve blanking plugs
from permanently set packers. The Type B PRT consists of two parts: the body with the
washpipe threads on both ends and a J-Sub with a small-diameter workstring thread.
The body has a built-in stop and two internal lugs to control the J-Sub. The stop will not
allow the J-Sub to pass through the bottom of the body. Shear pins in the body lock the
J-Sub in position until the fish is engaged.
operation
The releasable engaging tool is spaced out so the fish will be engaged before the shoe
can come in contact with the packer or bridge plug. Once the fish has been engaged,
picking up will shear the pins and allow the body to be released from the J-Sub. Normal
packer milling operations are carried out from this point. When the string is elevated, the
J-Sub will re-engage the body.
Advantages
„„Packers
with tailpipe assemblies and without millout extensions may
be milled over and recovered in one trip
„„Constructed from heat-treated alloy steel
„„Wide selection of washpipe connections

M J-Joint
Product Family No. H14133
Application
The M™ J-Joint has a simple, two-piece design consisting of the outer body and the
double J mandrel.
The M J-Joint is used in conjunction with a washover assembly to burn-over and retrieve
packers in one trip. The three main advantages of this tool are the double J release, the
ability to pull out of hole and replace shoe without releasing engagement device, and
the ability to engage the fish with any type of fishing tool prior to the burn-over operation
and remain engaged through the operation.
The double J design of the mandrel eliminates the need to run any type of safety joint
below the releasing joint. This is a great advantage when a taper or box tap must be
used. The double J also makes it possible to use higher weights both up and down
without accidentally releasing..
Advantages
„„Any
type engaging mechanism may be run
the need for a safety joint
„„Easily releases and reengages multiple times
„„Can be manufactured with any washpipe connection
„„Manufactured from AISI 4140 heat-treated alloy steel

CP-3 Plug Plucker
Product Family No. H74714
Application
The CP-3™ plug plucker is used to retrieve Baker bridge plugs and cement retainers. The
plug plucker uses a latch with left-hand wickers that engage the thread bore like a spear.
The wickers are effective even if threads are slightly damaged or have become partially
filled with cement. After milling operations are complete, the remaining portion of the
plug or retainer is recovered in the same run.
operation
It is recommended to run a Baker boot basket and drill collars above the plug plucker.
Run the CP-3 plug plucker in the well and latch into the threads of the bridge plug or
cement retainer body by setting down no more than 5,000 lb (2 268 kg). Take an upstrain
to assure the latch is properly engaged. Once the latch is properly engaged, set down
approximately 10,000 lb (4 536 kg) to shear the shear screws. Milling operations can
now be performed.
Advantages
„„Bridge
plugs and cement retainers can be milled over and retrieved

The RatPACK
Product Family No. H14070
Application
The RatPACK™ retrievable packer impulse tool provides a source of impulses for items that are
friction-point stuck. Unlike jars, the RatPACK creates impulses versus high impacts on the fish.
It also has the ability to recover a fish in a matter of minutes The RatPACK fills the gap between
jars, which can only hit every minute or two with high impacts and surface vibrators. Surface
vibrators have limited effect on point- stuck equipment and in deviated or horizontal wells.
The RatPACK is designed to be run on a BHA directly above an engaging device to retrieve
retrievable packers and/or point-stuck equipment that cannot be pulled free. Some instances
where the packer cannot be freed are: limitations of the workstring or production tubing, junk or
sand on top of the packer, limitations of the workover rig or deviation of the wellbore. In most
cases, jarring would only cause the packer to become stuck tighter or there is a possibility of
jarring the mandrel out, causing the packer to then be recovered by washing over.
The tool operates by flow rates. By changing the rate of flow, the impulse rate varies directly. Tool
operation is independent of overpull. High or low overpulls can be applied while operating the
tool and makes the tool ideal for high-angle or horizontal wellbores. The tool does not require drill
collars or high- strength workstrings.
The tool uses clear fluid types such as water, brine or calcium chloride. The impulses caused by
the tool rattle and shake the packer free as opposed to the high-load impacts that are seen with
jarring strings. This makes The RatPACK the preferred method for recovering stuck retrievable
packers and point-stuck equipment.
Advantages
„„Fast
impulses in comparison to cycling jars
„„Reduces load factors on the workstring
„„Reduces load factors on the service rig
„„Operation is independent of overpull or set-down loads
„„No need to run drill collars
„„No need for high-tensile workstring
„„Works quicker than jars
„„425,000 lb (192 776 kg) tensile rating

Type E Cut and Pull Spear
Product Family No. H12213
Application
The Type E™ cut and pull spear is a Type E spear modified for rotation to be run in tandem with the
multi-string cutter. It is available in two sizes: one for 9-5/8-in. (244.5-mm) –11-3/4-in. (298.5-mm)
casing; and one for 13-3/8-in. (339.7-mm)–30-in. (762-mm) casing. The spear replaces a trip with the
conventional marine swivel and cutter, therefore trip time is reduced to a single trip.
The spear has a drive mandrel with 19 in. (483.0 mm) free travel that rotates inside the slip body
and a thrust bearing in the bottom sub. By incorporating a right-hand set and a left-hand release, the
spear is in the set position at all times when cutting. A fishing bumper sub with a minimum of
20-in. (508.0-mm) stroke is required to release the spear. This also allows the downward movement
of the spear to keep weight off the knives of the cutter when releasing.
Operation
Make up multi-string cutter, 20-in. (508.0-mm) stroke bumper jar, spacer subs and stabilizer so that
distance from cutter knives to stop ring on spear is at the correct depth at which you want to make
the cut. Run in hole until stop ring lands on top of casing to be cut. Rotate 1/2 in. round to the right,
pull on spear to make sure spear is set. Maintain 5,000–10,000 lb (2268–4536 kg) overpull on spear
while cutting. Start rotary and pump pressure as called for in the multi-string cutter manual. If casing
cannot be pulled or knives have to be changed out, slack off 19 in. (483.0 mm) to close spear and
apply 1/2 in. round left-hand torque. Spear can now be pulled to surface.
Advantages
„„Simple
design and operation

Universal Wellhead Retrieving System
Product Family No. H12215
Application
The universal wellhead retrieving system is run in conjunction with a multi-string cutter (capable of cutting
multiple strings of casing) to provide a one-trip method for removal of a subsea wellhead from the sea floor.
Operation
The universal wellhead retrieving system consists of an adjustable lift lug assembly and landing collar
positioned on an inner mandrel. The lifting mechanism is supported on the mandrel by a thrust bearing,
thereby permitting the mandrel to rotate. The multi-string cutter, mounted on the bottom of the mandrel,
is rotated by rotating the mandrel. The lift lug assembly is designed to engage an internal upset in the
wellbore. This technique provides positive engagement and eliminates the reliance on the penetration of
wickers into the ID of the wellhead. Lift lug engaged diameter is controlled with interchangeable sleeves.
Depth of lift lug position in the wellhead is controlled by adjusting the placement of the landing collar.
The stabilizer, multi-string cutter, ring- type space-out assembly, necessary pup joints or pony collars and
bumper jar are made up below the universal wellhead retrieving system for correct cutting depth. Longstroke bumper jars or slack joints are made up on top of the tool. The tool is run in the well in the release
position. The top of the wellhead is slowly tagged with landing ring and 1/4 in. round of left-hand torque
is applied at the tool; 50,000 lb (22 679 kg) –300,000 lb (136 080 kg) is pulled over the workstring weight.
Rotating torque is established. Recommended pump pressure is slowly applied as needed to operate the
multi-string cutter. Cutting continues until the pipe is cut.
If the operator is unable to cut the pipe and needs to disengage the universal wellhead retrieving system, he
can slack off until the J-lug engages J-slot. Slight right-hand rotation may be needed. After engaging J-slot,
the system is picked up. This action will put the tool in the release position. The operator can now pull the
tool out of the hole.
Advantages
„„Simple
operation
adjusted to catch wellheads of all manufacturers
„„Will not damage sealing areas

Marine Swivel Seal Extractor
Product Family No. H17002
Application
The marine swivel/hanger seal extractor is used exclusively
on floating rigs to suspend a cutting string in a fixed vertical
position. To accomplish this, the marine swivel/hanger seal
extractor must land on a fixed point in the riser, blowout
preventer or subsea wellhead. For cutting larger casing strings,
after the riser has been removed, adapter rings can be added
to the marine swivel/hanger seal extractor. The addition of
the hanger seal extractor, which replaces the adapter ring
and blank bottom, enables this tool to extract the hanger seal
assembly from a subsea wellhead.
The marine swivel seal extractor lands onto an intermediate
casing hanger in an 18-3/4-in. (476.3-mm) subsea wellhead.
The integral seal extractor snaps into the casing hanger
seal assembly when landed. To operate effectively in either
application, a slack joint or long-stroke bumper jar should
always be run above the marine swivel/hanger seal extractor.
This will eliminate premature movement of the swivel and
also reduce the drill string flex, resulting in an uneven cut.
After the intermediate casing string is cut, the casing hanger
seal is released with a straight pull. A ring-type space-out
assembly (product family no. H17035) is run below the swivel
so the cutter is positioned at the desired cutting depth if knife
changes have to be made.

Hydraulic Casing Backoff Tool
Product Family No. H14210
Application
Hydraulic casing backoff tools are used to back off casing at a known or desired coupling
location. They are often used as an alternative to running a casing patch during a casing
repair program.
Operation
The typical hydraulic casing backoff tool assembly consists of one stand of drill collars,
mechanical collar locator, lower anchor section, backoff section, upper anchor section,
pump out sub, several stands of drill collars and workstring. Normally the casing is cut
and pulled then the hydraulic casing backoff tool is used to remove the stub.
The tool is assembled and run in the well to the desired depth. The mechanical collar
locator pinpoints the collar to be backed off and the backoff tool straddles the collar.
The anchor sections are set hydraulically and the tool is then cycled until breakout is
accomplished. The pump is turned off and the workstring picked up. This releases the
anchors and allows the tool to be tripped out of the well. The backed off casing is then
retrieved with an appropriate spear.
Advantages
„„Eliminates
blind backoffs of casing and allows operator to back off casing at
known depth and location
„„High torque breakout capacity
„„Anchor sections contain special carbide insert slips, which make firm bites
into casing ID to withstand torque output of tool
„„Leaves threaded connection for reengaging with new casing string. Maintains
full casing integrity when casing is screwed back together properly
„„Eliminates restricted ID after repairing casing
„„Simple design consists of the top anchor section, backoff tool and lower
anchor section
„„No left-hand workstrings required for backoff
„„Eliminates over torquing of tool joints in workstring, saving connections
„„Can be used with tubing as a workstring, if necessary

Hydraulic Reversing Tool
Product Family No. H14110
Application
hydraulic Reversing Tools are used to apply breakout torque and to unscrew lengths of
drillpipe, tubing, or drill collars.
Operation
The reversing tool is made up to the top of a typical fishing string (i.e., a left-hand
box tap, taper tap, or overshot; a left-hand J-joint and one or more joints of left-hand
drillpipe). A 5-ft (1.5-m) pup joint, bumper, and oil jars; 4-6 drill collars, crossovers, and
the workstring are then added above the anchor section.
Note: All connections above the anchor section are right-hand. The tools are run in the
well and the fish is engaged. Anchor slips are set with pump pressure, then bled off and
the collar weight is lowered onto the anchor section. Next, the tool is pressured up to
make backoff. When the fish connection breaks, a decrease in pump pressure will occur.
The reversing tool is cycled until the connection is completely backed out. Then the pump
is turned off and the workstring is picked up. This releases the slips in the anchor section
and allows the fish to be tripped out of the hole.
Advantages
„„Good
for deep directional wells

Washover Drill Collar Spear
Product Family No. H14014
Application
Washover drill collar spears are used with washover strings to catch and recover drill collars
and pipe that have become stuck off bottom. The spear enables washover, backoff and recovery
operations in a single trip and eliminates the problem of stripping fish out of washpipe by
allowing the fish to be positioned at the bottom of the washpipe string.
Operation
The washover drill collar spear is run inside the washover pipe, set in a control bushing near the
bottom. The inside assembly generally consists of a screw-in sub, taper tap, box tap, or other
fishing tool, J Type™ safety joint and drill collar spear. The washover assembly is run in and
slacked off over the top of the fish until the screw-in sub or tap makes contact and the inside
assembly is made up into the fish. The washpipe is then slacked off to proceed with washover.
When the fish falls free during washover operations, the spear automatically catches it.
Advantages
„„Saves
time and reduces number of trips by combining washover, backoff and
recovery operations in a single trip
„„Reduces risk of losing fish during washover operations
„„Eliminates fish and hole damage from dropped fish

Hydraulic Pulling Tool
Product Family No. H14027
Application
The hydraulic pulling tool pulls objects from cased wellbores using hydraulic
pump pressure. The tool is designed to anchor in the casing, exert a pulling force
on the fish below and transmit this force to the casing rather than the surface
equipment. This design allows the pulling tool to be used with most conventional
workover rigs and small workstrings. The pulling tool may be used to pull liners,
retrievable packers or any other objects that require heavy pulling strains.
The pulling tool is composed of three sections:
„„The
relief valve—which is run on top of the tool, allows release of the slips
if differential pressure exist at the tool. It also prevents pulling of a wet string.
„„The anchor section—which is run immediately below the relief valve,
anchors the tool to the casing wall. The anchor section provides a large slip
engagement area to safely transmit the heavy pulling strains with minimum
risk to the casing.
„„The pulling section—whichis run below the anchor section. A blanking sub
is run below the pulling section so that hydraulic pressure may be applied.
The pulling tool may be used with mechanical fishing tools, such as an overshot,
spear or screw-in assembly.
Advantages
„„Operates
off rig pumps or reversing unit
be used with:
•• small workstring
•• low weight capacity workover rig
•• any mechanical fishing tool

Expanding Hydraulic Mill
Product Family No. H15098
Application
Expanding hydraulic mills are run above drill bits or mills to open the casing ID to a greater
diameter than drift. They can be used to scrape casing ID to remove scale or cement prior
to running a packer and can also function as hydraulic stabilizers to centralize the cutter
when cutting casing. Blades can be dressed with METAL MUNCHER™-style carbide inserts
to remove steel or cement or with hard metal for stabilizing. Various weights of the same
size casing can be milled with one set of blades, due to the unique design of the tool’s
stop collars.
Operation
Prior to running, the expanding mill’s stop collars are mechanically set to maintain true
full-bore gauge milling and reaming. The expanding mill is made up to the mill or bit and
run in the hole with sufficient drill collars to maintain 2,000–5,000 lb (907–2 268 kg)
of weight on bottom. Nozzles in the bit or expanding mill should be sized to provide a
suggested pressure drop of 500 psi (34 bar), which will keep the blades expanded during
milling. Light weight is maintained on the mill and torque is monitored. When the operator
is satisfied that all restriction has been removed, the hole is circulated clean, the pumps
are stopped and the tools are tripped out of the hole.
Note: Can also be used as a torque barrier (i.e., coiled tubing milling operations).
Advantages
„„Rugged
design enables tool to expand and scrape casing ID and
function as a hydraulic stabilizer when cutting casing

Drilling Safety Joint
Product Family No. H15025
Application
The drilling safety joint is designed to provide a means of disconnecting from the
bottomhole assembly (BHA) or a nonreleasable engaging tool without the use of wireline
or a manual backoff. The drilling safety joint can be easily made up, released and
reengaged and it will still withstand all normal operations.
Operation
The drilling safety joint consists of a top half, friction ring, and a lower half. Springloaded pins keep the friction ring attached to the top half. The friction ring keeps the
safety joint from unscrewing during normal operations. It permits transmission of full
torque in the makeup direction but considerably less torque in the release direction.
o-rings seal off both internal and external pressure. When needed, the drilling safety
joint will easily release to retrieve the string above it.
Advantages
„„Simple

Casing Jack System
Product Family No. H18556
Application
On abandonment jobs, casing jacks can help free stuck casing and pull enough
pipe to lower the overpull, allowing the rig to finish pulling the casing out of
the hole. On jobs where casing is rehung in the wellhead, casing jacks provide
pull necessary to reset the casing hanger at the original tension at which the
casing was run, regardless of the type of rig on the well.
Operation
After the jack system is set up and the manifold connected, a casing spear and
drillpipe pup joint are made up and inserted into the top of the casing. Then,
the spear is set with enough of the pup joint sticking up to set the top set of
slips. With upper and lower slips in place, the jacks are slowly cycled and the
casing picked up in the wellhead. Once the casing hanger is high enough above
the bottom-slip area, the bottom slips are set and the casing hanger removed.
For rehanging jobs, the casing hanger is replaced and the jacks removed once
the decided tension is applied. For abandonment jobs, jacking continues until
the casing is free enough for the rig to pull.
In cases that do not permit the use of the jacking spool, two wide flange beams
to support and stabilize the jacks may be used.
Advantages
„„Combined

Application
The kelly drive bushing is a pup joint with a hex-shaped middle
body section 10 ft (3.04 m) long. A split bushing that will fit pin
drive or square drive rotary tables is set around the body for
transmitting torque.
Operation
The kelly drive bushing is spaced out in the string so the engaging
tool or washover assembly will be at the top of the fish when
the body of the bushing is in the rotary table. The bushing is then
installed. Once the top of the fish has been engaged or swallowed by
the washover assembly, the bushings are removed and the kelly pup
joint is left in the string during the fishing or washover operation.
Advantages

J-Type Safety Joint
Product Family No. H14037
Application
J-Type™ safety joints provide a simple, yet effective means of releasing and re-engaging
fishing tools, particularly those such as taps or die collars that are normally not releasable.
J-Type safety joints can be used as backoff connectors on washover jobs to save rig time
by connecting to the washed-over fish while the washover pipe is in the hole.
Operation
The J-Type safety joint is a two-piece unit that is secured when lugs on the top half
engage with a J-Slot on the bottom half. Special shear screws keep the tool securely
fastened until the fish is engaged. Once the fish is engaged, a tension load of 10,000 lb
(4 536 kg) per shear screw is applied to the string. When the screws have been sheared
and the tension released, the string is elevated while applying slight left-hand torque.
The lugs then shift into the release slot and the two halves of the safety joint separate.
To reengage the safety joint, the string is lowered while rotating slowly to the right until
the lugs on the top half engage the slots in the lower half. Rotation is then stopped;
right-hand torque is maintained and the string is lowered until the joint is fully engaged.
The joint remains engaged until the releasing procedure is repeated. Standard operation
is as a left-hand release and right-hand connection tool. Right-hand release and left-hand
connection configurations are available through special order.
Advantages
„„Provides
a release option from tools such as taper taps or die collars, which
are normally nonreleasable
„„Provides a way to connect or disconnect fishing string and stuck fish
„„Shear screws prevent accidental unlatching of the J-Type safety joint before
engagement with the fish
„„Simple construction allows easy makeup and release
„„Accessory parts such as a packoff sub and two different stingers are available
for operations that require circulation through the safety joint to the fish

Washover Backoff Safety Joint (Full-Opening)
Product Family No. H14038
Application
The washover backoff safety Joint is a
multipurpose safety joint installed in the
washover string in place of the washpipe drive
sub. The washover backoff safety Joint can be
used like standard drilling safety joints. In the
event of a washover string becoming stuck,
the washover backoff safety joint can easily
be backed off from the surface so the fishing
string above the washpipe may be recovered.
Operation
In a washover and backoff situation, the
Washover Safety Joint, run in conjunction
with the J-Type™ safety joint, makes it
possible to wash over a stuck string, screw
into the fish and perform a backoff.
Once the fish has been screwed into and it
is established that the fish cannot be pulled,
the J-Type safety joint can be released
to allow the washpipe to reciprocate and
rotate. Once a string shot has been run just
above the J-Type safety joint, the fish can be
reengaged and backed off. If the washpipe
will not turn freely to the left, the anti-friction
ring of the washover safety joint will allow
this point to unscrew. The long threaded area
makes it possible to back off all tool joint
connections and most tubing connections
without completely unscrewing the washover
safety joint.
Advantages
„„Available
in most washpipe and tool joint connections
„„Saves rig time by making it possible to wash over, back off, and recover in one trip
„„May be used as standard washover safety joint

Whipstock Systems, Anchors, and Retrieving Tools
Application
Whipstocks are used to sidetrack a wellbore for many reasons such as re-entry of an existing wellbore,
a drilling bottomhole assembly (BHA) that has become stuck and is too costly to fish out, severe
formation or drilling problems, the need to change the direction of a wellbore or the need to drill
multiple exits from a single wellbore.
They are available in both permanent and retrievable versions, with three retrieving tool options to
accommodate even severe hole conditions. Whipstocks produce a kick-off point with exact depth control
and a precise direction. The complete system includes a whipstock orientation device, anchoring device,
and a milling system.
Dual-string exits have now become commonplace and triple-string exits completed successfully. Recent
advances in directional drilling technology, combined with advances in whipstock technology, have
sparked a substantial increase in sidetracks from existing wellbores.
A sidetrack from an existing wellbore can normally be completed for two-thirds the cost or less when
compared to a new well. Baker Hughes has led the industry with new products in this area, such as the
one-trip WindowMaster™, G2™, Multilateral (ML) Whipstocks and TorqueMaster™ anchoring systems.

WindowMaster Whipstock System
Product Family No. H15094
Application
The WindowMaster™ whipstock system is the first true one-trip window cutting system. The WindowMaster
whipstock system can be run in hole, oriented to the new hole direction, anchored in place and a window
completely milled, all in one trip. This state-of-the art system saves substantial rig time by eliminating at least
two round trips with drillpipe, which are required by conventional window-cutting systems. In addition, the
WindowMaster whipstock system eliminates the risk of mill connection and body failure during milling.
The system is retrievable when run with the TorqueMaster™ bottom trip anchor or TorqueMaster packer in
conjunction with retrievable anchor. Two retrieving tool options ensure retrievability within a wide variety of
hole conditions. The WindowMaster BHA has been refined using finite element analysis (FEA). During every
window-cutting application, when milling the casing and drilling the rathole, the milling BHA is subjected
to severe combined loads of cyclic bending, torsion and compression. These high-stress points in the BHA,
which approach or exceed the failure limit of the BHA, have been identified through FEA. The geometry and
metallurgy of the WindowMaster whipstock system distributes these stresses uniformly throughout the
length of the BHA. This reduces the level of high-stress peaks at the connections and on the mill body to a
level substantially below the minimum yield strength of the material.
By shifting this excess stress to areas specifically designed to handle it, Baker Hughes has virtually eliminated
any chance of twist-off during the milling operation. The more evenly distributed stresses during milling also
result in minimum damage to the whipstock, which greatly enhances the success if retrieval is required.
The WindowMaster window mill has been engineered using the Baker Hughes renowned METAL MUNCHER™
cutting structure. METAL MUNCHER technology enables the operator to mill the window quickly and
efficiently, without sacrificing window quality and while applying minimum weight and torque to the
workstring. The resulting cuttings are small and easily circulated out of the hole.
Advantages

one trip with drillpipe to complete window

WindowMaster G2 Whipstock System
Product Family No. H15153
Application
The new WindowMaster G2™ whipstock system combines a one-trip feature with a full-drift OD
window mill. The full-drift window mill requires less rathole to be drilled, which saves valuable
rig time. The WindowMaster G2 can be run in hole oriented to the new hole direction, anchored
in place and a window completely milled, all in one trip. This state-of-the art system saves
substantial rig time by eliminating at least two round trips with drillpipe, which are required by
conventional window-cutting systems. In addition, the milling BHA eliminates the risks of mill
connection and body failure during milling.
The system is retrievable when run with the TorqueMaster™ bottom trip anchor or TorqueMaster
packer in conjunction with a retrievable anchor. Two retrieving tool options ensure retrievability
within a wide variety of hole conditions. The system is also compatible with the Baker Hughes
new PathMAKER™ formation mill, which provides exceptional milling and drilling performance in
hard formations. When used together, the WindowMaster G2 whipstock system and PathMAKER
formation mill can provide several hundred feet of rathole if required to fit large rotary steerable
drilling assemblies out of the casing. The WindowMaster G2 window mill has been engineered
using the Baker Hughes renowned METAL MUNCHER™ cutting structure. METAL MUNCHER
technology enables the operator to mill the window quickly and efficiently without sacrificing
window quality and while applying minimum weight and torque to the workstring. The resulting

PathMaster Whipstock System
Product Family No. H15151
Application
The PathMaster™ whipstock system combines the one-trip and retrievable features of the field-proven
WindowMaster™ whipstock with a shorter whipstock ramp and full-gauge mills. This system provides
a quicker kickoff with a higher build rate in short-radius drilling applications. Decreased length of the
whipstock and a milling assembly consisting of only a window mill and watermelon mill combine to
form a significantly shorter window exit BHA. The reduced-length BHA is capable of passing through
higher doglegs in the wellbore.
The PathMaster whipstock system provides an effective means to exit casing and provide a window
to run drilling BHA, liners and completion equipment through. In one trip the starting cut is made,
window is milled and pilot hole is drilled. The system can be set with a TorqueMaster™ packer/anchor
combination or the torquemaster bottom trip anchor.
Advantages
„„Full-gauge
mills provide a drift window and rathole
„„Short whipstock ramp provides quick kickoff
„„Shorter overall BHA allows system to pass through high doglegs
„„Only one drillpipe trip required to mill casing exit and drill pilot hole
„„Retrievable for multiple zone applications
„„Allows MWD, UBHO, or gyro into packer for orientation
„„Uses patented METAL MUNCHER™ cutting technology for faster, cleaner cuts

Whipstock Systems
Product Family No. H15039
Application
The hydraulic-set PathMaster™ and hydraulic WindowMaster G2™ whipstock systems enable
the use of hydraulically activated anchor and packer systems with proven one-trip whipstock
systems. These systems provide a secure hydraulic communication link to below the whipstock,
which enables whipstock anchoring devices to be hydraulically activated and set and the casing
window milled in one trip. A production injection packer (PIP, product family no. H30039) or
TorqueMaster™ hydraulic-set retrievable anchor (product family no. H15040) may be activated
and set directly. In addition, a TorqueMaster permanent packer and removable anchor (product
family no. H41518) or retrievable TorqueMaster packer (product family no. H64501) may be
activated and set using the hydraulic setting module and adaptor kit (product family no. H41518).
When run with the hydraulic whipstock valve (product family no. H15036) and any of the abovementioned anchoring systems, the hydraulic-set PathMaster and WindowMaster G2 whipstock
system can be run in oriented using MWD (or wireline gyro survey tool), hydraulically anchored in
place and the casing exit milled in one drillpipe trip. This eliminates any drillpipe or wireline trips
associated with setting a bridge plug or whipstock packer before running the whipstock.
Window milling performance is identical to the non-hydraulic versions of the PathMaster and
WindowMaster G2 whipstock systems and, when run with retrievable anchors, whipstock retrieval
is also the same.

Hydraulic Whipstock Valve
Product Family No. H15036
Application
the hydraulic whipstock valve allows normal circulation, drillstring fill-up, as well as MWD
operation while running the WindowMaster™ whipstock system. The valve allows the use
of a hydraulic set anchor, bottom trip anchor or TorqueMaster™ packer in conjunction with
hydraulically operated equipment run above the whipstock.
The use of MWD whipstock orientation, closure of flow to the annulus, setting the packer
and complete milling of the casing is accomplished with one trip of the drillpipe. The valve is
actuated hydraulically by varying the flow rate in the drillpipe. Manipulation of the drillstring
is not required. Internal pressures above and below the valve are equalized relative to the
annulus to prevent accidental actuation due to differential pressure across the valve. The valve
is actuated at a flow rate considerably higher than that required for normal MWD operation;
therefore the packer will not be set accidentally during normal MWD orientation.
Operation
Determine the normal flow required for running the MWD equipment, the maximum flow rate
attainable from the pumps and the mud weight. Consult the nozzle chart in the tech unit for the
respective tool size to determine the appropriate nozzle size. To shift the valve after the MWD
operations are complete, increase the flow rates to the maximum charted shear flow rate for
the respective tool size. Tool will activate and then close and lock. Annulus communication is
sealed off and normal circulation through bottom is regained.
Advantages
„„Valve
allows integration of field-proven systems
„„Whipstock can be oriented, packer set and complete casing exit milled in one trip
„„Manufactured from heat-treated alloy steel for maximum service life
„„Multiple exit ports prevent valve from clogging during MWD operations
„„Compression sleeve protects snap ring from contamination so valve will
close reliably
„„ID below valve is isolated from fluid flow and debris

trips to mill the window; this can now be done
in one trip, saving the customer time and money.
The PathMAKER formation mill is designed to fit
both the PathMaster™ and WindowMaster G2™
whipstocks to provide true one-trip casing exits
in hard formation.
Advantages
„„PDC
capable of milling steel and formation
by the world leaders in casing exits and drill bits
„„Spiral-set cutter alignment for smoother, cleaner cuts
„„Cutter placement controls drilling fluid to efficiently cool and clean
cutter elements
„„Mills window and drills an extended rathole if needed in one trip
„„Allows directional drilling to begin immediately after casing exit
„„Cuts hard formation casing exits in one trip
„„New mill designs are compatible with all hydraulic whipstock systems
„„Engineered
Specification Guide
The formation mill has new enhancements to
improve milling and drilling performance. The
specially engineered spiral-set cutter alignment
reduces vibration, while the large water courses
keep the PDC cutters cool for increased durability.

EXCLUDER Sub
Product Family No. H15038
Application
The EXCLUDER™ sub is used with the retrievable whipstock to prevent debris from getting
around the anchor or packer assembly.
Operation
The first EXCLUDER is placed in the string assembly below the whipstock to prevent debris
from falling down around the anchor or packer during milling or washover operations. A
second Excluder sub is placed directly above the anchor or packer and below the emergency
shear-type disconnect. This forms a back-up barrier to prevent any residual debris from falling
down during washover or retrieval operations.
Advantages
„„Debris
barrier prevents debris from accumulating around the anchor or packer
„„Can be run as a debris barrier on all whipstock systems
„„Port above cup to prevent swabbing during retrieval

Unloader Valve
Product Family No. H14040
Application
The unloader valve helps prevent the swabbing of the well by providing an exit path
for the fluid which has entered the excluder port.
Operation
The unloader valve is placed below the excluder sub in the retrievable whipstock
assembly. When pickup force above a predetermined level is applied to the
whipstock assembly, the shear screws shear and the unloader valve's outer mandrel
shifts. This upward stroke acts as an indicator that the whipstock is free and opens
fluid flow ports which allow well fluid to pass through the excluder mandrel, thus
preventing well swabbing. The unloader valve transmits torque via the hexagonal
profile of the inner mandrel.
Advantages
„„Prevents
well swabbing during whipstock retrieval
locked to withstand high torsion loads

Shear-Type Disconnect
Product Family No. H14030
Application
The shear-type disconnect is a safety release shear joint that is run below a retrievable
whipstock assembly. This tool allows the recovery of the whipstock should the anchor or
packer fail to release.
Operation
The shear joint separates by pulling a tensile force greater than the value of a selected
shear ring. When the prescribed overpull is exceeded, the shear ring will shear and
the whipstock and all components above the shear type disconnect can be recovered
from the well. An external fishing neck profile will be left facing upward in the well.
An overshot and fishing jar can then be used to engage this profile and retrieve the
remaining portion of the disconnect and the anchor or packer.
Advantages
„„Allows
recovery of whipstock should packer or anchor fail to release,
ensuring whipstock recovery even in worst case scenarios
„„The joint is rotationally locked
„„Adjustable shear ring values allow same tool to be dressed for different
release loads

TorqueMaster Bottom Trip Retrievable Anchor
Product Family No. H15054
Application
The TorqueMaster™ bottom trip retrievable
anchor is used to anchor a whipstock in place
in the wellbore. It is an alternative to the
packer/anchor assembly and it attaches to
the lower end of the whipstock by means of
a drillpipe thread. The bottom trip retrievable
anchor is for use with the WindowMaster G2™
and the PathMaster™ window milling systems.
Operation
To activate the setting sequence only a bottom
restriction is required. This bottom can be in
the form of a permanent or retrievable bridge
plug, top of cement, liner top, production
packer, etc. When using the retrievable
bottom trip anchor, either the UBHO or the
MWD orientation method can be used. The
anchor is retrievable with straight overpull on
the whipstock. For retrievable applications, a
debris management system consisting of an
excluder, unloader and emergency disconnect
should be run between the whipstock and the
anchor. The debris management system will
keep debris from falling around the anchor and
possibly fouling the slips during retrieval.
Advantages
„„No
welded components
„„Does not require circulation to activate
„„Retrievable design allows for slip retraction, which prevents scarring casing
during the retrieval process
„„Uses the proven TorqueMaster cam-cone slip system to eliminate risk of rotation
„„Short length

TorqueMaster Hydraulic Set Retrievable Anchor
Product Family No. H15040
Application
The TorqueMaster™ hydraulic set retrievable anchor is used to anchor a whipstock in place
in the wellbore. It is an alternative to the bottom trip anchor assembly and it attaches to
the lower end of the whipstock by means of a drillpipe thread. It is used with the hydraulic
WindowMaster G2™, or the hydraulic PathMaster™ window milling systems.
When used with the hydraulic whipstock valve, the MWD orientation method can be used.
The anchor is retrievable with straight overpull on the whipstock. For retrievable applications,
a debris management system consisting of an excluder, unloader and emergency disconnect
should be run between the whipstock and the anchor. The debris management system will
keep debris from falling around the anchor and possibly fouling the slips during retrieval.
Operation
When the whipstock reaches the desired setting depth, a MWD tool can be used to establish
correct orientation. Once the whipstock is properly oriented, flow rate is increased to close the
hydraulic whipstock valve. Pressure can now be applied to the hydraulic-set anchor to secure
the whipstock in the casing; 350–500 psi (24.1–34.5 bar) is required to shear each of the
3/8 in -16 UNC shear screws. After shear screws are sheared, lower cone will ratchet up shear
sleeve. When the lower cone has moved up a sufficient amount, the retrievable TorqueMaster
slips will begin to move outwards and bite into the casing ID.
Flat ramps on the upper cone provide a cam surface under the slips. Torque forces are
therefore transmitted directly into the slips. As additional torque is applied, the slips become
tighter in the casing. To retrieve the anchor, a predetermined overpull is applied to the
whipstock to shear the shear screws.
Advantages
„„Does
not require a restriction in the wellbore to activate
design allows for slip retraction, which prevents scarring during the
retrieving process
„„Uses the proven TorqueMaster slip system to eliminate risk of rotation
„„Redressable
„„Wide setting range

TorqueMaster Permanent Packer and Removable Anchor
Product Family Nos. H41518 and H41519
Application
The TorqueMaster™ packer permanently orients a TorqueMaster whipstock anchor at a desired
location in a cased hole for sidetrack operations.
The lower cone and torque slips are designed to withstand torque loads up to 20,000 ft-lb
(27.1 kNm). Flat ramps shaped on the lower cone provide a cam surface under the slips. Torque
forces the slips outward, engaging the casing bore. The slip tooth pattern encircles virtually all
of the casing ID, locking the packer in place, holding torque and axial loads.
The internal guide key of the packer is used to locate the whipstock anchor and survey
instruments. The guide key design is superior to other designs; no welding is required to hold
the key in place. The key is enclosed and cannot be knocked out of place.
The TorqueMaster whipstock anchor uses proven Baker Hughes bonded seals to seal the
packer bore. After the packer is set and a survey is made, the anchor is easily oriented on the
surface to the desired direction. The anchor allows 360° full rotation, adjustable in
3° increments. Latching the anchor into the packer bore isolates the zone and prevents any
movement of the whipstock.
TorqueMaster Whipstock Packer
Product Family No. H41518
The Baker Hughes TorqueMaster packer and removable whipstock anchor system is a variation
of the Baker Hughes TorqueMaster whipstock permanent packer system, which allows
multiple stab-in and stab-out of the whipstock anchor after the packer has been set.
This allows the lower zone to be produced after removing the anchor or to space out for
another lateral.
Patented Cam-Cone System
Advantages
„„Only
one directional survey required
„„Packer bore is open before landing anchor, allowing debris to fall through
„„Anchor stinger does not extend below bottom of packer, allowing easy stab-in even
if packer is set on top of cement
„„No welded components
„„Packer provides isolation of zone below; no cement plug needed
„„Piston inside of anchor allows easy stab-in even with closed fluid volume
below packer
„„Oriented easily on location without breaking any premium or API thread connections

Retrievable TorqueMaster Packer
Product Family No. H64501
Application
The retrievable TorqueMaster™ whipstock packer incorporates all the performance
enhancements of the field-proven permanent version with the added benefit of one-trip,
full retrievability. The system is rated for 20,000 ft-lb (27.1 kNm) of torque, 7,500 psi
(517.1 bar) and 350°F (177°C) when run with the reliant packing element system. It is
designed for multilateral applications where the lower zone requires isolation during drilling
of the upper zone. It can be run in conjunction with the WindowMaster™ one-trip window
milling system and the multilateral whipstock system. When run with the WindowMaster
system, only one trip is required to orient the whipstock, set the packer, and mill the
window. Once the lateral is completed, the entire system then can be retrieved with one
drillpipe trip. After retrieval, full-bore access to the lower lateral is again restored.
Advantages
„„Packing
element above slip system to prevent debris from fouling retrieval
„„Retrieval system not affected by tailpipe weight or differential pressure
„„Weldless construction
„„Rated for 7,500 psi (517.1 bar) and 350°F (177°C)

TorqueMaster ML Packer
Product Family Nos. H41540, H41541,and H41542
Application
The TorqueMaster™ ML packer design provides permanent orientation for drilling
multiple laterals while retaining a primary completion bore below the packer.
The lower cone and torque slips are designed to withstand torque loads in excess of
20,000 ft-lb (27.1 kNm). Flat ramps shaped on the lower cone provide a cam surface
under slips. Torque forces slip outward, engaging casing bore. Slip tooth pattern
encircles nearly all of the casing ID, locking the packer in place, holding torque and
axial loads.
A special 180° orienting clutch is machined directly into the packer body. This design
is superior to lug design seen on other products because shear and bearing failures
are virtually eliminated. The milling anchor, production anchor, and survey instrument
use a clutch for orienting purposes.
The TorqueMaster ML milling and production anchors use proven Baker Hughes
bonded seals to seal off the packer bore. After the packer is set and survey is
made, the milling and production anchor can be easily oriented on the surface to a
desired direction. Both anchors allow 360° full rotation, adjustable in 3° increments.
Latching the anchor into the packer bore isolates the zone and prevents any
movement of whipstock or lateral entry guide.
A tailpipe assembly is recommended for installations, which includes a landing
nipple for a debris catcher. This can be with or without a mill-out extension, both
being of equal length to accommodate the debris catcher.
Standard material grade for packer and production anchor is 4140–4142 (18-22 Rc)
alloy steel. The packer and anchor can be ordered with (corrosion-resistant alloy)
CRA materials and Aflas® elements. Pressure rating of the tool is 7,500-psi (517.1-bar)
differential at 70°F–300°F (21.1°C–148.9°C). The packer can be wireline set or
hydraulically set on tubing using standard adapter kits and setting tools.

Fixed Lug Whipstock Retrieving Tool
Product Family No. H15051
Application
The fixed lug retrieving tool is the primary method of engaging the WindowMaster™ whipstocks
and removing them from the wellbore. There are two primary methods of retrieving a retrievable
whipstock: the fixed lug and the special taper box tap, but it is recommended that the fixed lug be
used first, due to the ability to release from the whipstock.
Operation
Recommended bottomhole assembly includes the fixed lug, jars and drill collars. The lug is
lowered to the correct measured depth and slowly worked up and down. If the lug does not
engage, turn the workstring and work up and down again. Repeat this process until the lug
engages. The lug can also be orientated with either a MWD or gyro. Once the lug engages, follow
recommended procedures for releasing the anchor or packer below the whipstock. With the lug
engaged, weight can be set down on the lug without disengaging from the whipstock. This will
allow recocking of the jars. The fixed lug can be released by applying a small amount of right-hand
torque and lowering the lug through the neutral point.
Advantages
„„Solid
body construction for strength and durability

Application
Pilot milling is used to mill away complete sections of
casing from either the wellhead or the liner hanger down
to desired depth. This is done in conjunction with slot
recovery on a fixed platform or to sidetrack in openhole
below the casing shoe. METAL MUNCHER™ turbo mills
provide extended blades for extra mill life.

In most cases, pilot mills are capable of milling faster
than the cuttings can be removed from the well. Section
milling is used to remove the entire casing from a
section of the well. Primarily section milling is done in
conjunction with side tracking.
Drill Collars
Drill Collars
Underreaming tools provide a means to go through a
string of casing and open up the wellbore to a larger
size. This can be done to improve a cement job or to
expose new formation for a gravel pack. With any
of these tools, it is recommended to run drilling jars,
string mills for stabilization and shock subs to minimize
vibration at the mill.

METAL MUNCHER Pilot Mill (Patented)
METAL MUNCHER Turbo Pilot Mill
Product Family No. H15121
Application
The METAL MUNCHER™ pilot mill is a high-performance mill used for milling washover pipe, casing,
and liners. The blade design continuously indexes a new cutting surface during milling. The insert
design produces small, uniform and easy-to-handle cuttings. The METAL MUNCHER turbo pilot mill
is available with 18-in. (457-mm) blades for slot recovery and long sections of casing to be milled.
Operation
The METAL MUNCHER pilot mill should be run with a shock sub and sufficient drill collars to provide
a wide range of milling weights. Both weight on mill and RPM will be determined by penetration
rate, torque and cuttings removal. Pilot milling with METAL MUNCHER inserts should be treated as a
machining process rather than a milling process. Once the optimum weight and RPM is established,
it should be adhered to.
The METAL MUNCHER cutting structure provides a high rate of penetration. This will require a mud
system capable of suspending the cuttings and carrying them to the surface. Special consideration
should also be given to additional surface equipment to handle cuttings.
METAL MUNCHER Pilot Mill
Product Family No. H15121
METAL MUNCHER pilot mills are available to cut all standard sizes of casing and can be
manufactured for any size. The mills can be manufactured with a connection down for milling
applications that are too close to surface to run sufficient drill collar weight above the mill.
Advantages

the pump gauge shows a definite pressure
drop of 200 psi (13.8 bar), indicating that
the casing has been cut through, pressure
is increased until the annular velocity is
sufficient to bring cuttings out of the hole.
RPM and weight on mill may be adjusted to
obtain optimum mill performance.
The D section mill should be run with a
minimum of 10,000 lb (4 536 kg) of string
weight in the bottomhole assembly (BHA). A
bit or mill is run to help the tool enter the hole
and stir cuttings during milling operation. The
cut is started slowly, approximately 2–5 ft
(0.6–1.5 m), above a coupling, then brought
to a speed of 80+ RPM for the cut-out. The
pump is started and the number of strokes
increased to give a minimum pressure drop of
400 psi (27.6 bar) across the mandrel nozzle.
During cut-out, approximately 1 in. (25.4 mm)
After milling for 3–5 ft (0.9–1.5 m), rotation
continues and the pump is stopped while
picking up off the casing. Pressure is allowed
to equalize and rotation is stopped while
picking up into the casing above the cut point.
Pressure is then resumed and slacked off
into the window. The resulting pressure drop
verifies cut-out and removes any shavings
that may have entered the tool while making
the window cut-out. Milling operations
are continued.
Advantages
„„Operates
hydraulically for fast, efficient downhole milling
„„Knife design reduces long stringers and removes casing in short chips for easy
lift and removal by the drilling fluid
„„All six knives are used for the initial cut-out, reducing cut-out time, and
minimizing the chance of bent or broken knives

LOCKOMATIC Section Mill Dressed With
METAL MUNCHER Cutter
Product Family Nos. H15079–H15089
Application
The LOCKOMATIC™ features a positive, direct lock, and unlock mechanism for expanding drilling
and milling tools. The LOCKOMATIC is as reliable as the drill string itself, because the lock is
an extension of the drillstring. There is direct control of the tool—it's as if the lock were in the
driller's hand. The LOCKOMATIC is unmatched for hole opening, underreaming and casing milling.
Operation
Cutter arms are locked closed during run-in. Tool hang-up is prevented by a patented feature that
damps off downhole hydrostatic pressure from the pressure ports.
Circulation pressure moves the body and cutters upward by increasing the annular volume
between the kelly and upper body. Because the patented LOCKOMATIC mandrel lock remains in
place as part of the drillstring, the cutter arms cam out over the mandrel lugs, forcing the cutters
to expand. On box down models when the bit is also cutting, applied drilling weight helps cutter
expansion and maintains cutter expansion.
On reaching gage, the cutters lock in place and stay locked as long as pressure and/or drilling
weight is applied. The tool will not take true drilling weight until the cutter arms are locked out to
full-gage cutting position.
To retrieve, release pressure and pick up on tool. This retracts the mandrel lock from under the
cutters. If chips and cuttings penetrate the collapsing mechanism, the pull of the draw works will
force obstructions out of the way and close cutter arms. Springs and hydraulics are not involved.
The LOCKOMATIC retrieves as easily as the drillstring. Tool sizes range from 3-3/4 in. (95.2 mm)
closed gauge to 48 in. (1 219.2 mm) open gauge.

Standard VACS System
Product Family No. H13125
Application
The VACS™ tool is designed to capture cuttings downhole and prevent metal cuttings or junk
from reaching the surface during milling operations. The VACS tool consists of a jet bushing,
a drive sub, washpipes, triple connection bushing, screen joint, and bushing and a diverter
tube. This allows for conventional circulation down through the workstring while performing a
reverse circulating action downhole. This tool is ideal for keeping cuttings from accumulating
inside a subsea BOP stack, deepwater riser or becoming suspended in the milling fluid.
Operation
Position the VACS tool within 60–120 ft (18.3 m–36.6 m) above your milling assembly.
Establish normal milling procedures for the particular application being performed. During
milling operations, the cuttings will travel up through the center of the milling tool and up
through the diverter tube, where the cuttings will fall out as the milling fluid flows through the
screen and out the jet bushing.
Advantages
„„Keeps
subsea BOPs clean of cuttings
cuttings do not become suspended in the drilling or milling fluid
„„Traps all cuttings downhole
„„Can be used with all non-hydraulic milling tools
„„Can be used to remove large amounts of debris from the bottom of the well
„„Reduces mud cost
„„Debris volume can be increased
„„Mud yield and viscosity are not a factor in the tool’s performance
„„Captures cutting during milling operations

VACS Jet Basket Application
Product Family No. H13096
Application
The VACS™ jet basket is an effective tool used in
the recovery of junk from the well bottom. The
jet basket operates on the principle of convective
acceleration. The fluid exiting the jet ports creates
a suction at the base of the tool, pulling in any
loose debris from the well bottom into the junk
barrel, where it is held by the tool’s junk catchers.
Operation
Make up the VACS jet basket at the bottom of
the workstring. Trip in hole; circulation through
the tool can take place any time if desired. Before
bottom is tagged, make up the kelly and begin
circulating through the tool until you are at the
well bottom. Establish parameters above the
junk, stop circulation and break the kelly to drop
a steel ball; the kelly is then made up. To seat
the ball, circulate 3/4 of the workstring volume or
allow approximately 1,000 ft (304.8 m) per minute
for the ball to fall. After the ball seats, optimum
running pressure for this tool should be in the
range of 1,500–2,500 psi (103.4–172.3 bar). With
pumps running, begin rotating slowly
(30–60 rpm) while easing the jet basket to the
bottom. Continue to work the tool by raising the
string off the bottom and slowly slacking off while
rotating. To help prevent the screen from clogging
when recovering small junk, periodically shut the
pumps down when the tool is off bottom and then
restart the pumps. This should rearrange the junk
in the jet basket to help improve suction. After
this motion of raising and lowering the string has
been run for a few minutes, stop rotation and shut
the pumps off to pull out of hole.
Note: If required, a small core can be cut before
pulling out of hole. If a core is cut, the maximum
size should be the distance from the face of the
basket head to the back of the catchers inside the
basket head. When ready to recover jet basket
with core, shut off pumps and stop rotation. If a
core has been cut, there will be a slight overpull
when the core breaks. To help break the core,
it may be necessary to burn over the core by
rotating a few times without circulation. Pull out
of hole and at surface, remove basket head and
inspect retrieved junk.
Advantages
„„Simple
operation
tools cover almost all casing and hole sizes
„„Low maintenance with quick disassembly and reassembly
„„Ability to circulate through the tool before washing over the junk
„„Washpipe connections at jet bushing allow for extensions to be placed in tool
„„Jet bushing section can be removed to convert to a globe type junk basket
„„Core can be cut if desired

Globe-Type Junk Basket
Product Family No. H13022
Application
The globe-type junk basket is used to recover any type of small objects that may be in the
wellbore. It is a simple design, which consists of a hollow milling head, a double set of free
rotating finger catchers, middle body and top sub. By adding the Baker Hughes jet bushing
associated with the Baker Hughes jet basket, the globe type junk basket can be turned into a
reverse circulating junk basket.
Operation
The globe-type junk basket is positioned in the well just off bottom. Circulation and rotation
parameters are established. The successful operation of the globe type junk basket requires
that a core be cut from the formation. Any junk that may have obstructed normal drilling will be
recovered above the core. If no recovery is made, but a good core is recovered, in most cases
normal drilling may continue.
Advantages

Grabitz Magnet
Product Family No. H13101
Application
The Grabitz™ magnet is added to the bottomhole assembly (BHA) to help collect ferrous metal debris
from the wellbore and wellbore fluid, which is then retrieved to surface. The tools can be used in
applications such as packer milling, window milling, junk milling or during designated clean-out
runs. The tool is particularly effective when run in conjunction with other special wellbore cleaning
tools such as the ULTRA-CLEAN™ casing scraper and ULTRA-CLEAN brush sub. The Grabitz magnet is
also used to help clean metal debris such as cuttings or milling debris from casing collars, horizontal
wellbores and subsea BOP stacks. The tools can also be used in wells with low annular velocities,
wells that contain fluids with poor carrying capacities and in wells where circulation is a problem.
The Grabitz magnet is used as part of the Baker Hughes wellbore cleaning system, which also
contains the VACS™ system, Multi-Task Wellbore Filter™, shear-type swivel and circulation valve,
BOP jet sub, Clean Bore Riser Brush™, ULTRA-CLEAN casing scraper, wellbore test packer, and
ULTRA-CLEAN brush sub to form a complete one-trip wellbore cleaning system.
Operation
The Grabitz downhole magnet can be incorporated in a BHA as needed depending on application.
For packer milling jobs, the tool should be placed a joint above the top boot basket; for collection of
perforating gun debris, the tool should be placed below the perforating guns; for cleanout runs the
tool should be placed above scrapers and brushes.
The magnets of the Grabitz downhole tools are very strong and can affect the operation of computers,
watches and pacemakers. It is recommended to not let anyone wearing a pacemaker within 2 feet of
a tool. Caution should also be used as the strength of the magnets can easily cause hands or fingers
to be mashed or trapped between the magnets and loose objects.

Type B Boot Basket
Product Family No. H13016
Application
Type B™ boot basket is used to trap cuttings that
are too large to circulate out of the hole during
drilling, milling; or junk fishing operations. The
design of the boot basket traps junk by producing
a sudden decrease in annular velocity when the
cuttings pass the larger OD of the boot reaching
the smaller OD of the body and top connection.
Operation
The Type B boot basket should be run as close
as possible to the mill, bit or junk basket. Milling
procedures are carried out as usual with normal
circulation. Additional boot baskets may be run in
tandem to increase the junk- catching capacity.
Advantages
„„Simple

to trap cuttings too large to be circulated out.
The washpipe connection eliminates the need
for a crossover bushing. The washpipe boot
basket with the third inner connection is used
for packer milling and recovery operations. In
both operations, components of the BHA are
eliminated, reducing the risk of BHA failure.
The washpipe boot basket is available in
most of the smaller washpipe sizes. The inner
connections are available with 8 round or packer
retrieving tool connections.
Operation
The washpipe boot basket should be run as
close as possible to the mill. Milling procedures
are carried out as usual with normal circulation.
Additional boot baskets may be run in tandem to

360° Clean Bore Casing Scraper
Product Family No. H16105
Application
The 360° clean bore casing scraper cleans cement, mud, rust, scale, paraffin, perforation burrs,
and other restrictions from the inside wall of casing.
Operation
The casing scraper is run with the pin up and a bit or mill is installed on the box end. The
bit serves as a guide and prevents plugging of the circulation holes through the scraper. For
maximum scraping efficiency, it has been found desirable to run the scraper completely through
the restricted section without rotation, then pull back up and make a rotary run through the
section. This cleans most of the scale, cement and other extraneous materials off the casing
wall. Rotating the tool as the string is lowered causes the scraping surface to shear off any
remaining burrs or obstructions missed on the first pass with the scraper. The scraper is rerun to
check for smoothness before tripping out of the hole. If the weight indicator does not show any
irregularities, the casing should be clean.
Advantages
„„Body
constructed from a solid piece of AISI 4140 heat-treated alloy steel for strength
blades provide endurance and maximum service
„„Cleaning can be accomplished by either rotation or reciprocation as a result of blade
arrangement in the body that gives full 360° contact with the casing ID
„„Each blade is cut with left-hand helical grooves to allow the tool to scrape up or
down inside the casing
„„Double protection downhole results from blades held securely by blade retainers
locked in place by keeper screws

ULTRA-CLEAN Casing Scraper
Product Family No. H16107
Application
The nonrotating/rotating casing scraper is used
to remove mud or cement sheath, perforation
burs, rust, mill scale, paraffin, and similar
substances from the casing ID. This is especially
important in precompletion stages where tight
tolerance equipment will be run. These scrapers
are also a very effective component of the BHA
when making gauge runs. Other accessories
that can be run with the ULTRA-CLEAN™
casing scraper are Multi-Task Wellbore Filter™,
Grabitz™, VACS™, MF™ circulating tool, jet subs,
mills, or bits.
One of the key benefits to this tool is the option
to run it in the rotating or nonrotating mode.
When in the nonrotating mode, the blades and
optional brushes remain stationary and the pipe
can be rotated for long periods while circulating
to clean the wellbore, without the worry of
wear to the casing ID. In addition when in the
nonrotating mode, should the scraper become
stuck, straight overpull will shear a ring and
allow the safety clutch to engage, putting the
scraper in the rotating mode, and allowing
it to be worked free using torque, overpull,
circulation, and jarring.
Stainless steel brushes are also an option with
the ULTRA-CLEAN casing scraper. The brushes
are installed above the scraper blades, to scrape
then brush the casing ID during run in.
The tool has a rugged design and contains
no external bolts that could work loose under
extreme conditions. For this reason, the
ULTRA-CLEAN casing scraper is recommended
for use when drilling cement on the cleanout run.
Advantages
„„Nonrotating
mode eliminates risk of damaging or wearing casing when rotating drillstring
„„Scraper can be dressed in rotating or nonrotating modes, by simply relocating a shear ring
„„No bolts, clamps, or threads that can work loose and allow blades to be left in the hole
„„Nonrotating cylindrical brush may be installed above scraper blades to optimize
performance by allowing scraping then brushing in one run
„„Safety clutch allows scraper to go from nonrotating to rotating mode with overpull,
should the tool ever become stuck, allowing it to be worked free. Should the tool ever
have to be washed over, the clutch will also keep the tool components from spinning
„„Hard metal applied to scraping edges on blades to provide endurance and
maximum service
„„Spring mounted blades provide 360° contact with the casing ID
„„Shims are also available to keep the tool centralized in deviated wells, when centralizers
are not run above/below the ULTRA-CLEAN casing scraper

ultra-clean Brush
Product Family No. H16108
Application
The ULTRA-CLEAN™ brush tool is used to brush and clean the ID of casing. It is designed to
remove scale, rust, mud residue, and any other particles of debris that might be brushed from the
casing ID. The tool can be run by itself or as an integral component of the Custodian™ wellbore
cleaning system with the ULTRA-CLEAN casing scraper, Multi-Task Wellbore Filter™, shear-type
swivel and circulation valve, Grabitz™, VACS™ tool, BOP jet sub and Clean Bore Riser Brush™.
The ULTRA-CLEAN brush tool features self-centering, nonrotational stabilizers to keep the
nonrotating brush sleeve centered in the hole, preventing wear or damage to the casing. This
ensures 360˚ brush coverage and eliminates uneven brush wear while allowing for rotation of the
heavy-duty main mandrel in straight and high-angle holes. Another benefit of the tool is a special
safety clutch that can be activated should the stabilizers or brush sleeve ever get stuck. This will
allow torque to be transferred to the entire tool for working it free or washover contingencies
should it ever become necessary. The tool is designed with ample room to allow for bypass of
debris through the special spring steel brushes and stabilizers.

Multi-Task Wellbore Filter
Product Family No. H13015
Application
The Multi-Task Wellbore Filter™ will allow
collection of debris from the wellbore wall,
brushing of the wellbore wall and filtering of
fluid all in one run. It is designed to seek out
junk, collect it, then carry it to surface. It is a
modular tool and can be run in conjunction with
Grabitz™, bits, casing scrapers, stabilizers, etc.
The standard filtration media on The Multi-Task
Wellbore Filter is field-proven BAKERWELD™
stainless steel screen, however slotted or
perforated liners or a combination of these, can
also be used. Debris capacity can be optimized
by simply changing the length of screen and
adding an extension to the mandrel. It is
primarily for use in precompletion stages of
the well's construction, but can be run anytime
the wellbore has become contaminated with
debris, such as after a milling operation. The
Multi-Task Wellbore Filter will help prevent
the common problems associated with
stuck completions or liner equipment due to
unexpected debris in hole.
Operation
To operate the tool, simply make up in the
string, verify bypass operation, and run in hole.
When run in hole the tool will act as a boot
basket allowing collection of large debris using
fluid flow as it passes through the tool. When
pulling out of hole, the bypass is closed and the
tool now diverts fluid through the filter media
capturing the debris. To clean out debris at
surface, simply unlock the cleanout windows at
bottom of tool and remove debris.
Advantages
„„Acts
as boot basket collecting debris during run in
„„Collects debris from wellbore during run in, then filters wellbore fluid when
pulling out of hole
„„Optional stainless steel brushes can be run below non-rotating cups, allowing
brushing and filtering with a single tool
„„Filter mechanism can be slotted liner or BAKERWELD screen with variable gauge
to suit all fluids and debris types
„„Large bypass area for fast run in
„„Large cleanout windows located at bottom of tool for easy cleanout of debris
„„Rigid with full tensile and torsional ratings through tool

J-Type Circulation Swivel
Product Family No. H14146
Application
The J-Type™ circulation swivel (JTCS) is normally used to locate at a known point, such as a liner
top, shear down to put the tool in the swivel/circulate mode and open ports for high-volume
circulation at the tool.
The JTCS has two primary positions. In the stroked-open position, it allows fluid flow and torque
to be fully transmitted through the tool. In the closed or sheared position it acts as a swivel and
allows for high volume circulation at the tool through the ports in the tool. The tool is activated to
the closed position by functioning the J mechanism, allowing for circulation at the tool and rotation
above the tool. The JTCS has been successfully tested at 100 RPM and 20,000 lb set-down weight,
with no damage to the bearing and no reactive torque transmitted to the workstring below the
tool. Once circulation is complete at the tool, the lugs may be re-engaged closing the ports and
allowing weight to be transmitted to the wellbore test packer for performing an inflow test.
The tool can be used with a polishing mills or dress off tools where polishing a PBR/liner top
or drilling cement is required. As part of the full wellbore cleanup system, the JTCS can be run
in conjunction with the wellbore test packer, Multi-Task Wellbore Filter™, Grabitz™ downhole
magnets, VACS™ junk basket, ULTRA-CLEAN™ casing scraper and brush or jetting subs.
Advantages
„„Allows
for rotation of entire string or only above the tool
„„Allows for positive circulation at the tool or all the way through the string below
„„Tool can be run as part of a complete wellbore cleanup system
„„No drop balls or darts required

Shear-Type Circulation Valve and Swivel
Product Family No. H14046
Application
The shear-type circulation valve and swivel (STCVS) is normally used to locate at a known
point such as a liner top, shear down to put the tool in the swivel/circulate mode and open
ports for high volume circulation at the tool.
The STCVS has two primary positions. In the stroked open position it allows fluid flow and
torque to be fully transmitted through the tool. In the closed or sheared position, it acts as a
swivel and concurrently provides ports for high-volume circulation at the tool. The tool can
even be used in applications where polishing a polished bore receptacle/liner top or drilling
cement is required. For cement drilling applications the shear activation can be set to higher
values, if needed. Shear-type swivel and circulation valves are available with a 7-3/8-in.
(187.3-mm) OD with NC 50 connections and 5.00-in. (127-mm) OD with NC 38 connections. The
tool can be run in conjunction with polishing mills, dress-off tools, Multi-Task Wellbore Filter™,
Grabitz™, VACS™, ULTRA-CLEAN™ casing scraper and/or jetting subs.
Operation
The primary feature of the STCVS is the ability to shear down and rotate only above the tool,
while rotation below the tool is prevented. When weight is applied to put the tool in the closed
position, it also opens ports in the tool, allowing high-volume circulation uphole through the
STCVS. Straight pickup will close the ports, restoring positive circulation through the tool,
and allowing rotation of the string below the tool to take place again. This procedure can be
repeated as needed.
Advantages
„„Allows
for rotation of entire string or only above the tool

Dart-Activated Circulation Sub
Product Family No. H14078
Application
The dart-activated circulation sub is designed for circulating at high flow rates to boost the annular
velocity in areas of the well such as above a liner top or where casing sizes change. The tool is
normally run in hole in the closed-to-annulus position and pumping through the tool. A dart is then
dropped from surface, opening circulation ports at the tool for high rate circulation. Once circulation
is completed an additional dart is dropped, allowing for the tool to be closed for circulation back
through the tool. The tool is positioned close to the liner top when total depth is reached.
Multiple tools with different dart sizes may be run in the same string if more than one open-close
cycle is needed. A catcher sub is required to retain the darts once they have passed through the
tool. The tool is designed to be used as part of the wellbore cleanup system as an alternative to
the J-Type™ circulation swivel for applications where the hole is highly deviated and the drag on
the lower string may become a problem. The tool is also used in conjunction with the wellbore test
packer to pressure test the liner top.
Operation
Once the lower liner section has been circulated clean, a dart is dropped from the surface and the
tool is activated to shift a piston into the open-to-annulus position. This allows large volumes of
fluid to be pumped at higher flow rates above the liner section where the tool is positioned. Once
the desired volume of fluid has been pumped, a second dart is dropped and pressure applied to
the tool, which then returns the flow path through the lower assembly (i.e., the closed-to-annulus
position). The darts are then retained in the ball/dart catcher sub (product family no. H14077).
Advantages
„„Tool

Ball/Dart Catcher Sub
Product Family No. H14077
Application
The catcher sub is available in two configurations, one for catching drop balls and the other
for darts. Sufficient bypass area is built into the tool to allow full flow around the balls or darts
once retained in the inner sleeve.
The ball catcher is used with several tools and is available in two sizes. The inner sleeve has a
reverse-flow ball stop near the upper end to retain the balls in the event of reverse circulation.
The dart catcher sub is a required accessory used in conjunction with the dart-activated jet
sub, the dart-activated circulation sub and the wellbore test packer. The catcher sub retains
the activation darts used to open and close these tools once the dart has been released from
the tool. As the dart is pumped into the catcher sub, the restricted ID allows the differential
pressure created by this restriction to force the dart into the inner sleeve where the darts are
retained. The inner sleeve is designed with a hook near the upper end to retain the darts in the
event of reverse circulation.
Advantages

Pump-Out Sub
Product Family No. H14061
Application
The pump-out sub is designed to allow circulation above a plugged fish to avoid pulling
a wet string and for well control purposes. The simple design consists of the main body,
piston and shear pin. The pump-out sub may also be used with a mud motor when
extended circulating times are foreseen after the motor operations are complete.
Operation
Position the pump-out sub in the workstring as close as possible to the engaging device
being used.
Once the fish has been engaged and it is established that circulation is not possible
through the fish, the ball is dropped down the drillstring to the piston. Additional pump
pressure shears the shear pin allowing the piston to shift. This allows circulation
through the side ports.

Circulation Control Joint
Product Family No. H14024
Application
The circulation control joint is a multipurpose tool, designed to provide a means of
establishing circulation at a predetermined hydraulic pressure. The tool may be used as
a pump-out, kick, run-in or drain sub by variation of the particular control washer/rupture
disc/restriction plug combination. The standard circulation control joint has an inner bore
profile that forms a seat for restriction plugs fitted with a bit nozzle. The control washer
and bit nozzle IDs can be varied to obtain the correct relationship between mud flow and
pressure drop to burst the rupture disc and establish the desired flow rate.
The circulation port can be resealed at any time by removing the standard restriction
plug (short fishneck) and inserting an extended (long fishneck) restriction plug. Both
restriction plugs may be recovered with slick line using a restriction plug spear.
Advantages
„„Provides
a circulation point if a plugged fish is engaged
pulling a wet string
„„Can be used as drain or kick sub
„„Circulation port can be resealed from surface
„„Contains a minimum ID large enough for free point and backoff tools
„„Maintains same rupture pressure from both sides of the disc
„„Eliminates

Clean Bore Riser Brush and Boot Basket
Product Family No. H13014
Application
The clean bore riser brush and boot basket is designed to clean the ID of drilling
and production riser systems. The tool is used to brush and wipe mud residue,
cement or other debris from the riser inside wall and recover them to surface.
Recovery is done with a boot basket that is designed in with the brush/wiper
assembly and built on a mandrel that is full drillpipe strength. The tool can be
rotated and short-tripped with the BOP jet sub and Multi-Task Wellbore Filter™. It
can also be run as part of the Baker Hughes wellbore cleaning system along with
Grabitz™, shear type circulation valve and swivel, ULTRA-CLEAN™ casing scrapers,
VACS™ tool, Multi-Task Wellbore Filter and BOP jet sub.
Operation
Typically the clean bore riser brush is picked up with the BOP jet sub and surfacedressed Multi-Task Wellbore Filter, which make up the upper cleanout assembly.
The upper assembly is then short-tripped with the lower string of cleanup tools in
the hole. It is spaced so the BOP, wellhead and riser areas are cleaned while the
lower string is cleaning the area where the completion packer is to be set. Once
the BOPs have been jetted, the upper cleanout assembly is pulled out of hole.
The lower assembly is then run back in the hole and the cleanup program can
continue. The upper cleanup assembly can also be short-tripped after the lower
clean-up has been done and is being pulled out of hole.
Advantages
„„360°

BOP Jet Sub
Product Family No. H14068
Application
The BOP jet sub was developed to wash
debris and clean out the BOP, risers, wellhead
area and casing, and tubing anchors. The tool
incorporates several nozzles that provide a
hydraulic jetting force. Circulation through
the jet sub is possible by means of a piston
held in place with shear screws preventing
flow through the nozzles. This enables the
BOP jet sub to remain inactive until other
tool operations have been completed. Other
options that can be run with the BOP jet sub
are Multi-Task Wellbore Filter™, ULTRACLEAN™ casing scraper, Grabitz™, shear-type
circulation valve and swivel and the VACS™
tool to form a one-trip well-cleaning system.
When the operation of other tools has been
completed, a restriction plug is dropped from
surface. Once the restriction plug is inside
the piston, hydraulic pressure on the piston
provides the force needed to shear the shear
screws. The piston will be pushed below the
nozzles so that a majority of the wellbore
fluid will be pumped through the BOP jet
sub nozzles. The restriction plug includes
a carbide nozzle so that fluid can still be
pumped to the bottom of the workstring.
The restriction plug contains an internal
fishneck so it can be retrieved by wireline
if necessary.
Operation
The BOP jet sub is positioned in the
workstring so that when the workstring
reaches total depth, the BOP jet sub will be
below the BOP. At this time, other work can
take place with normal circulation through
the workstring. When it is time to clean the
BOP, the restriction plug is dropped from
surface. Pump pressure is applied to the
piston to shear the shear screws. The piston
will now move down below the jetting
nozzles, allowing for circulation through the
nozzles. The BOP, riser or other areas may
now be cleaned.
Advantages
„„Screw-in
jetting nozzles that can easily be changed to adapt to pump capacity
full flow
„„Simple design and operation
„„Can lie dormant in the drillstring until activated or short-tripped with restriction plug
„„Balanced piston will not open prematurely

Dart-Activated Jet Sub
Product Family No. H14068
Application
The dart-activated jet sub was developed
to wash debris and clean out BOPs and
risers, wellhead areas and casing and tubing
anchors. The tool incorporates several
nozzles that provide a hydraulic jetting force.
Circulation through the jet sub is possible by
means of pistons held in place with shear
screws that shift from the closed-to-annulus
to open-to-annulus then back to the closed-toannulus position. This enables the dartactivated jet sub to remain inactive until other
tool operations have been completed. For
BOP and riser cleanout operations, the dartactivated jet sub can be run with the surface
junk catcher and clean bore riser brush for
cleaning this area. The dart-activated jet
sub can also be used with the Multi-Task
Wellbore Filter™, ULTRA-CLEAN™ non-rotating
casing scraper, ULTRA-CLEAN brush sub,
Grabitz™ downhole magnets,
J™-Type circulation swivel and the
VACS™ junk basket to form a one-trip wellcleaning system.
Operation
The tool is typically run in hole in the closedto-annulus position. When the operation of
other tools has been completed, a dart is
dropped from surface and the tool is activated
to shift a piston into the open-to-annulus
position. This allows for large volumes of fluid
to be pumped at higher flow rates. Once the
desired volume of fluid has been pumped, a
second dart is dropped and pressure applied
to the tool, which then returns the flow
path through the lower assembly (i.e., the
closed-to-annulus position). The darts are
then retained in the ball/dart catcher sub
(product family no. H14077). The dart contains
an internal fishneck so it can be retrieved by
wireline if necessary.
Advantages
„„Allows
jet cleaning of BOP and riser to be completed on the wellbore
cleanup trip, saving a trip in the hole
„„Screw-in jetting nozzles can be easily changed to adapt to pump capacity
„„Simple design and operation
„„Allows full flow
„„Balanced piston will not shift prematurely
„„Multiple open-close cycles are possible by using additional tools with
different size darts

Surface Junk Catcher
Product Family No. H13013
Application
The surface junk catcher is designed to capture falling debris not circulated out of the hole
when riser, BOP and wellhead areas are cleaned. The tool is normally run in the same trip as
the BOP jet sub and riser brush or can be short-tripped when the lower clean-out string is close
to total depth. The tool can also be used during scheduled BOP tests or when retrieving wear
bushing to prevent debris from being introduced into the wellbore.
Operation
The surface junk catcher can be run one stand below the BOP jet sub and located in the first
100 ft of casing below the wellhead. Throughout the jetting and cleaning process, any heavier
particles of debris that cannot be circulated out of the hole are caught in the integrated boot
basket when falling down the hole. A stabilized coil brush assembly above the boot basket
diverts falling debris into the boot. The large debris capacity of the tool can easily be extended
with minor modifications. Collected debris can easily be identified at surface through the large
clean-out window that can be opened at the bottom of the tool.
Advantages
„„Large
boot basket funnel traps larger particles of debris
full-bore protection with debris barrier contact to casing ID
„„Simple operation with no moving parts reduces risk
„„Window and flushing ports make surface junk catcher easy to empty at surface
„„Delivers

Wellbore Test Packer
Product Family No. H67242
Application
The wellbore test packer is designed to perform a negative inflow test on a liner top. The
wellbore test packer eliminates the need for a designated run with a retrievable packer. The
tool is normally run in the same trip as the wellbore cleanup tools. A polished bore receptacle
polishing mill and liner top dress mill can be run below the test packer.
The tools are spaced out so that the liner top dress mill reaches the liner top at the same
time that the cleanout tools reach total depth. The drillpipe is displaced with a fluid lighter
than the well fluid and back pressure is applied. The negative test can be done by slacking off
weight after landing on the liner top with the liner top dress mill, which closes the bypass and
expands the packing elements on the test packer. The heavier fluid column in the annulus is
isolated when the packer is set, eliminating hydrostatic forces on the liner top during the test.
Backpressure is bled off, the drillstring closed in and observation is done to detect pressure
increases from a possible leaking liner top. Should communication ingress at the liner top,
pressure will build in the drillpipe.
With the test concluded, the drillpipe is once again pressured to equalize the pressure across
the tool. Straight pickup is applied to open the bypass and unset the packing elements. The
lighter fluid column in the upper drillpipe is flowed back to surface as the heavier column of
fluid is allowed to U-tube and displace the lighter-weight fluid.
Advantages
„„Allows
for wellbore cleanup and liner test to be conducted in a single trip
bypass for rapid deployment
„„Simple to operate, with multiple resets
„„Enhanced design feature eliminates presetting due to liner top contact or high
compressive loads during deployment
„„Robust design allows for high torque and tensile capabilities
„„Large
