PACKER MILLING TOOL
TENSION PACKER
The ACT Tension Packer is a
retrievable, single grip tension set
packer, used in water flood, oil
production or treating applications.
This compact, economical packer is
used for shallow wells where
sufficient set down weight is not
available to utilize a set down
packer. It is set by left hand
rotation and has three release
methods.
- Sets securely in any hardness casing, including premium grades
- Compact, short, easy to transport and run
- Full opening enables maximum fluid circulation
- Rocker type slips eliminates the need for extra drag block
- Easy to operate – a simple and reliable J-Slot mechanism, actuated from the surface by tubing rotation, makes the packer easy to set and release
- One piece packing Three release methods, normal release, shear release and safety joint release
OPERATION:
- Run the packer to desired setting depth, and make the last movement down before attempting actual set
- Rotate the tubing to the left one-quarter turn at the tool, and pick-up on the tubing string to obtain pack-off.
- To release the packer, Lower the tubing string at least one foot more than is necessary to remove the applied tension (this will move the J-Pin to the top of the J-Slot) and rotate to the right sufficiently to obtain one-quarter turn at the packer. Should the Packer fail to release with normal procedures, an upward pull of the tubing string weight, plus 25,000 to 50,000 lbs. tension (dependent on strength of the shear ring) will release the packer. If it is not desirable or practical to pull 50,000 lbs. through the tubing, apply approximately 10,000 lbs. strain and rotate the tubing 15 to 20 turns to the right. This unscrews the left- hand safety thread between the Top Sub and the Body and allows removal of the tubing string and the Top Sub. To remove the remaining portion of the Packer, install a set of Jars made up above an overshot, or spear, engage the Packer Body, and actuate the Jars to free the Packer Body from the casing. Tension Packers are available for 4.1/2” to 9.5/8” casing sizes.
TUBING ANCHOR CATCHERINDEXING MULE SHOE
The Tubing Anchor Catcher (TAC) is
one of the most important tools in
achieving efficient rod pumping
operation. Run below a sucker rod
pump, it acts as an anchor to the
lower end of the tubing string to
maintain tension in the tubing
string and eliminates tubing
movement during the pump cycle. It
also acts as a tubing catcher to
prevent parted pipe from falling
into the well.
Rod pumping operation, with the
tubing hanging free, causes problems
like excessive wear of the rods,
tubing, casing, and pump, reduced
pumping efficiency, increased
operating costs such as increased
requirements of power consumption
etc. The elongation and contraction
of the tubing string along with the
rod string reduces the effective
pump stroke and thus reduces the
production rate. This also causes
tubing buckling which results in
tubing and casing wear, tubing
collar leaks, and metal fatigue
causing the tubing to part.
FEATURES:
- Increases pump efficiency Reduces operating cost by reducing maintenance and down time caused by casing, tubing or sucker rod wear
-
Simple operation: Rotates left to
set, right to release
Double grip slip prevents upward and downward movement -
Catches parted tubing
Straight pull emergency release with adjustable shear pin force
Easy and inexpensive to redress.
OPERATION:
Install the Anchor Catcher in
the Tubing String just below or
above the pump for best results. Run
to desired depth and rotate the
tubing to the left to set the Anchor
Catcher. To ensure the Anchor Slips
are solidly engaged with the casing,
hold left hand torque on the tubing
and pick up and set down several
times to be sure the Anchor Slips
are properly set in the casing. The
tubing will torque up when the slips
have set. Release the torque and
apply the required amount of tubing
tension.During this slip setting
operation, the strain should be at
least equal to the final strain that
will be needed plus full tubing
set-down weight.To pull the Anchor
Catcher, lower the tubing to release
the tension and rotate to the right
while working the tubing up and down
slightly. Should the Anchor Catcher
fail to release with normal
procedures, an upward pull of the
tubing string weight, plus the total
value of the Shear Pins will release
the Anchor.Tubing Anchor Catchers
are available for 4.1/2” to 9.5/8”
casing sizes.
T-2 ON/OFF TOOL
ACT T-2 On-Off Tool enables the
tubing string to be disconnected
above a packer for zonal isolation,
tubing retrieval, and temporary zone
abandonment. The tool contains an
internal lock profile for landing a
wireline plug to provide zonal
isolation below the packer. The tool
has two basic components, the
overshot mounted on the tubing
string and the stinger mounted on
the packer. The overshot disengages
with either a standard left release
or an optional right quarter-turn
release. Shear- up or shear-down
positions are compatible with the
packer setting and retrieving
styles.
The washover shoe on the overshot
cuts through debris. The seals in
the tool are retrieved with the
overshot to enable redressing at the
surface. Available with all common
wireline profiles, the stinger works
with industry standard blanking
plugs, standing valves, and
regulators.

MODEL DB HYDRAULIC SET PERMANENT PACKER
ACT Hydraulic-Set Dual Bore Permanent Production Packers are the hydraulically set one-trip completion packers, ideal for high volume production in high angle, extremely deviated well. These packers feature the largest possible bore through combined packer and seal accessory. The packer is run on the hydro-set anchor latch seal unit which is made up in the top of the packer via the left-hand threads on the latch and is set by applied tubing pressure. The DB packer requires some type of temporary plugging device such as a shear out plug or wireline blanking plug located close to the end of the tubing.
ADVANTAGES:
- Slim-line design
- Solid construction enables 50% faster run-in without fear of impact damage or premature setting, making significant rig-time savings possible
- Two opposed sets of full-circle, full-strength slips ensure packer will remain properly set

ADDITIONAL INFORMATION:
The Dual Bore Permanent Hydraulic Set
Packers have been designed to give maximum
strength, uniformity of setting pressure and
standardization of all alloy materials for H2S
service.
LOCATOR TUBING SEAL ASSEMBLY
ACT Locator Tubing Seal Assembly is the most basic packer sealing system for packers incorporating a sealing bore. It is run in the well on the production tubing string until its No-Go shoulder locates on the to of the packer. This positions one or more seal stacks in the packer’s seal bore and establishes a seal between the packer and tubing. When a locator tubing-seal assembly is landed in a packer, the tubing is normally set in compression to compensate for any contraction of the tubing during treating operations. However, it is not always possible or desirable to slack off sufficient weight, particularly in deep deviated wells. In such cases, additional length must be added to the packer’s seal bore using seal bore extensions and to the locator tubing-seal assembly using a combination of spacer tubes and additional seal units.
SEAL BORE EXTENSION
ACT Seal Bore Extension is used in completions where seal bore packer is used as a production packer and tubing movement is expected. Seal Bore Extension provides sufficient seal bore length so that long seal assemblies accommodate tubing movement while always remaining in the seal bore. Multiple seal bore extension can be coupled together using a concentric coupling to obtain more seal bore length. Seal Bore Extensions are available for all sizes of seal bore packer. Seal Bore Extension are manufactured from materials that comply with NACE MR0175 STD. For SSC resistant metallic material.
Application:
Completions
with seal bore production packers where tubing
movement is expected.
Benefits:
Easy to
install
Low cost solution
Facilitates
tubing replacement
ANCHOR LATCH SEAL ASSEMBLY
The ACT Anchor Latch Seal Assembly positions the
seal units in the polished bore of the packer at
the bottom of the available stroke. With a
slight amount of set-down weight, the anchor
latch will snap into the top thread of the
packer. This feature allows the upward pull to
be applied to the tubing string to positively
confirm proper location and operation.The
process to release the anchor is an upward pull
combined with right hand turns of the tubing at
the latch. The releasing mechanism of the anchor
makes it ideal for completions where tubing
movement is not desirable.
Standard anchor
latch assemblies are manufactured from materials
that comply with NACE MR0175 standards for
sulfide stress cracking-resistant metallic
materials and fitted with seal stacks with metal
backups. Viton, Aflas, and Chevron seals are
available for hostile conditions, such as
high-temperature, high-pressure, and sour
environments.
FEATURES:
- Easy snap-in-snap-out procedure
- Prevention of seal movement
- High-performance seals available for hostile environments
PACKER RETRIEVING TOOL
The ACT Packer Retrieving Tool is required to retrieve seal bore hydraulic set retrievable packer. Each packer has a unique retrieving tool but all have same basic design. Latch feature latch into the top thread of the packer. A pull shear the shear screw of collet support and release the packer. If packer cannot be released with the help of right hand rotation collet will be free from safety nut and latch can be backed out.
PACKER MILLING TOOL
General Description
The
ACT PRS Packer Milling Tools (Packer Retriever)
is an internally engaging fishing tool designed
for the retrieving of production packers. With
its accessory components (Stinger, Bushing and
Mill Shoe) it passes through the bore of the
packer, mills the packer slips loose and pulls
the packer after it has been milled over, all in
one trip. A Packer Retriever is assembled with
the proper size slip to engage the bottom of a
specific bore packer, and made up on the lower
end of sufficiently long stinger (extension) to
permit the Retriever to be lowered completely
through the packer during the milling operation.
The Bushing is provided with a box connection at
its lower end to attach the Stinger, also a pin
connection at the lower end for attaching Mill
Shoe, and a pin or box connection at its upper
end for connection to the run-in or fishing
string.
OPERATION:
Make up a complete ACT PRS Packer Milling
Tools consisting of Retriever, Stinger, Bushing
and Mill Shoe. Make sure that the tool is
compatible with Casing and Packer sizes and will
permit proper and safe operations of the milling
and retrieving operations.
Lower the
fishing string until the Mill Shoe contacts the
slips of the packer. Milling operations may
begin until drill off conditions are
established. Generally, light drill loads should
be used to start to enable the shoe to cut the
thin bevel upper parts of most packers away
until full mill shoe face contact is
established. Additional weight may be added to
establish optimum conditions. Rotary Speeds must
be established that are sufficient with a given
weight, to burn or abrade the carbide particle
matrix away to expose the successive new cutting
edges of carbide particles. When this condition
is established the Mill Shoe will cut almost any
metal with maximum efficiency. Start circulation
and right-hand rotation to mill away the slips
and seating element of packer. When the packer
begins to slide down the hole, stop rotation,
raise the fishing string to engage Packer
Retriever with packer and then pull the assembly
and fish from the hole. The best condition of
removal for most makes of full bore production
packers is to mill up the upper slips and
approx. half of the packing element before
retrieval is attempted.
TO RELEASE THE RETRIEVER
For any of several reasons, it may be
required to release the Retriever from the
packer. Release of the Retriever is accomplished
by elevating the fishing string until weight is
indicated. Lower the fishing string about three
to four inches. Rotate the string right hand and
slowly elevate the string to withdraw the
Retriever from the packer.
CONFIRM THE FOLLOWING:
-
That the Retriever is assembled with the
correct size slip for the packer to be
That the Stringer is sufficiently long to permit the Retriever to pass completely through the
That the Bushing and Mill Shoe are the correct size for the casing - Make up complete assembly to the fishing string. (Scrapers or drift tools should be run prior to running the Milling Tool to depth. The casing in which the packer is to be removed should be washed clean to the packer top and a fluid and pump equipment must be selected that will clean the mill shoe and remove all cuttings from the hole as the packer is mill-up)
- Lower the Retriever in to the hole on the fishing string and pass it through the packer. The Retriever must clear the packer bore and be in a free position below the packer before milling or rotating of the string. If there are restrictions below the packer such as perforated nipples, landing subs or tail pipe, extensions must be used to position the packer retriever well below these points so that the rotation of the string will not foul the Packer Retriever. Now, raise the fishing string slowly and carefully until it takes weight. This ensures that the Retriever will engage the packer seat.
MAINTENANCE
To guard
against mis-runs and to prolong the life of the
ACT PRS Packer Retriever it should be completely
disassembled, thoroughly cleaned, lubricated and
reassembled before storing. Exterior surfaces
may be either painted or lubricated to prevent
rust and deterioration.
INDEXING MULE SHOE
The ACT Indexing Mule Shoe facilitates stab in of seals into seal bores, even in deviated wells. The work string does not need to be rotated to orient the mule shoe. Axial movement of the work string against an obstruction rotates the mule shoe. If it still fails to enter the bore, the work string is lifted to re-engage the internal J-mechanism and the mule shoe will again rotate when set down load is applied.
KEY BENEFITS:
- Protected spring. Spring is not exposed either in the inner or outer portion of the tool
-
Spring cannot be overstressed, as set down
weight is taken through a load shoulder in the
tool
Internal bearings prevent spring wind-up during the indexing process
APPLICATION:
Stabbing in
seals into seal bore in deviated wells.
HYDRAULIC SETTING TOOL
ACT MODEL D, F AND ERD PACKER, can be set on tubing or drillpipe using a wireline adapter kit and a hydraulic setting assembly. These setting assemblies are particularly useful for setting permanent packers in high-angle, deviated wells such as those drilled offshore. The hydraulic setting tool assembly and packer are run to setting depth on the tubing string and a ball is dropped to the ball seat in the setting tool. Sufficient tubing pressure is then applied to set and pack off the packer. The pressure or combined pressure and tubing tension, parts the release stud in the adapter kit and frees the setting assembly from the packer for retrieval. The HST has a bottom connection that accepts common wireline-setting tool adapter kits.
APPLICATIONS:
-
Deviated or horizontal wells
Large-casing packers - Wireline-set seal bore packer completions
FEATURES, ADVANTAGES AND BENEFITS:
- The HST accepts common wireline adapter kits, enabling it to set all ACT permanent and retrievable seal bore packers
- The HST enables the well to be circulated before the packer is set, preventing debris accumulation
- The heavy-duty HST construction enables the packer assembly to be pushed into place in high-angle and horizontal wells, enabling the packer to be set where wireline deployment is difficult or impractical
