HYDRAULIC PACKERS
RHP – DB DUAL BORE HYDRAULIC SET RETRIEVABLE PACKER
The ACT MODEL RHP-DB Retrievable Packer delivers high performance with simplicity of design and desirable economics. The dual bore packer allows for a large ID through the packer by sealing in an upper seal bore. No tubing rotation required to fully set the packer. It has one-piece, self energizing packing element and features bidirectional slips below the packing element for maximum protection from debris fouling. This location protects the slips from being lost during retrieval or milling. A retrieving tool is required to retrieve these packers.
FEATURES:
- Simple design
- Easy to retrieve
- Large seal bore
- Hydraulic setting
- Hydraulically setting the packer avoids the need to rotate the work string in running or retrieving the packer, which simplifies procedures, improves efficiency, and saves rig time.
- The ECNER array system reduces the swab-off effect and facilitates center pack off by enabling supporting force to be applied to the outer elements.
ERD RETRIEVABLE SEAL BORE PACKER ‘R’
ACT Model ERD Retrievable Hydraulic Seal Bore Packer is a Retrievable Packer. Hydraulically set by pressure in the tubing. It is run with Hydraulic Setting Tool & retrieving is done independently from the Tubing, using a Retrieving Tool manipulated on a work string. This packer is ideally suited for highly deviated well both onshore & offshore.
APPLICATIONS:
Model ERD Retrievable Hydraulic Seal
Bore Packer can be use in oil
production wells or in water or gas
injection wells.
FEATURES, ADVANTAGES AND BENEFITS:
- Run & set with the Production Tubing Hydraulically setting eliminates the requirements for spacing out & opening & closing with the help of Sliding Sleeves for the displacement of fluids
- Effects on tubing (compression & tension) are transmitted to slips- there is no shear ring with limits these stresses
- Retrieval independent of the tubing using a Retrieving Tool. It can be lift to the bottom of the well with a By-Pass Blanking Plug in a Nipple to isolate the formation
MODEL FURY 25 HYDRAULIC SETTING TOOL
MODEL RHP-SR RETRIEVABLE HYDRAULIC PACKER SINGLE STRING
American Completion Tool Model
RHP-SR is a hydraulic set packer
that can be run in single or
multiple zone installations. It is
highly recommended for deviated
wells where conditions are not
suitable for mechanical or wireline
set packers. No tubing movement is
required or generated in order to
set the packer. This allows the well
to be kept positively controlled at
all times because the tubing is
landed and the wellhead installed
before circulating or displacing
well fluids prior to setting the
packer. Two or more packers can be
set either at once or in any desired
sequence.
The RHP-SR packer design features
bi-directional, one piece slips
located below a three element
packing system consisting of dual
durometer rubber elements. The slips
are fully enclosed in a shear pinned
slip housing which in turn is
protected by a full diameter guide
located below the slip housing. The
RHP-SR packer requires a means of
establishing a maximum of 3,500 psi
pressure inside the tubing at the
packer (for 7″ and smaller).
The hydraulic setting chamber is
adjustable between 900 to 2,500 psi
which allows the tubing to be
pressure tested before the packer
begins to stroke and set. Two
balanced pistons are utilized during
the setting process. The lower
piston moves down to set and anchor
the slips before the upper piston
moves upward to compress the
packing. This action imparts the
total setting force to both slips
and packing thus assuring a positive
anchor and pack-off. The pack-off is
retained by a one-piece ratchet ring
that locks in and stores the setting
force applied to both the slips and
packing elements.
The RHP-SR packer incorporates two
methods of release, straight pull or
rotation. Both methods are contained
in the same releasing nut which is
located at the upper end of the
packer. Straight pull release is
accomplished by shearing a
predetermined quantity of brass
retaining screws which frees the
tubing. Rotation release is
accomplished by approximately eight
right hand turns of the tubing which
also frees the packer. Straight pull
then is applied to completely relax
the packer for retrieval. The RHP-SR
packer can be ordered with only one
method of release if desired. A
positive acting equalizing valve is
also located in the releasing
section which automatically opens
during the releasing procedure to
equalize pressures and allow
circulation between the annulus and
tubing. In addition, a large
diameter fluid by-pass is located
inside the packing mandrel which
allows fluid passage for rapid
retrieving while reducing element
swabbing.
RHP-SPR HYDRAULIC SET RETRIEVABLE PACKER
The ACT RHP-SPR Packer is a hydraulic set single-string retrievable packer and may be used in virtually any production application. Tubing pump pressure is used to set the packer and the setting force is locked into the packer by a body lock ring. A large internal by-pass reduces swabbing when running and retrieving. The by-pass closes when the packer is set, and opens during the releasing process to allow pressure equalization. Shear screws are used to control the packer release. The shear release value is adjustable by adding or removing screws from the shear housing or by use of steel screws. The standard ACT Packers are designed for differential pressures up to 7,500 psi.
FEATURES:
- The straight-pull, shear-release pins are unaffected by differential pressure, enabling easy changes to the release force before running
- The double-grip system enables the packer to hold differential pressures securely from above and below, preventing packing-element movement and ensuring proper pack off
- All components are locked to prevent pressure build up or debris from pre-setting the packer, improving reliability when running the packer in the wellbore
- Adjustable shear release Straight pull release
POLISHED SEAL BORE RECEPTACLE
The ACT Polished Seal Bore Receptacle is designed for applications where a large ID must be maintained through the completion while accommodating extreme tubing movements. The ACT Polished Seal Bore Receptacle modular design allows tool to be easily converted from tension release to hydraulic release. The tension release and the hydraulic release incorporate a Polished Seal Bore Receptacle as well as a PBR seal assembly including 2 sets of working seal units and a debris barrier above and below the working seals. Both versions when combined with a hydraulic or hydraulic/ hydrostatic set can be run in and set in one trip. The polished seal bore receptacle can be retrieved in two trips. The seal assembly is retrieved when the tubing string is recovered. The PBR seal bore is retrieved with a PBR retrieving tool. The Polished Seal Bore Receptacle is available in varying lengths of up to 25 ft. in stroke. An adjustable shear mechanism locks the outer housing and seal mandrel together during run- in. Once the seal assembly is released, it is free to move in the bore, compensating for tubing movement. The PBR assembly can be pinned in the fully stroked, closed or midway position to accommodate pre-spacing in one-trip completions
APPLICATIONS:- One-trip installations in deviated or horizontal wells

OVERSHOT EXPANSION JOINT(OEJ) ASSEMBLY
ACT Overshot Expansion Joint (OEJ)
Assembly is designed for
applications where extreme tubing
movements are expected due to
stimulation or production of the
well and when a tubing separation
device is also required.
The OEJ assembly is a one-trip
system, which allows the well to be
flanged up prior to setting the
packer. The OEJ assembly
incorporates a slick joint sub as
well as housing – packing set
including working seal units and a
debris barrier above the working
seals. The plain receptacle, housing
– packing set and seals can be
retrieved when the tubing string is
recovered for maintenance or the
entire completion can be retrieved
by straight pull after ensuring that
J-pin engaged with J-slot, thus
allowing the packer to be retrieved.
The OEJ assembly is available in
varying lengths of up to 20 ft.
stroke. Adjustable shear pins lock
the inner & outer assembly together
during run-in. Once the shear screw
gets sheared by applying load, the
outer assembly gets disengaged and
it is free to move on the inner
assembly, compensating for tubing
movement.
