installation where the wellhead is flanged up before the
packer is set.

Features:-
• No tubing manipulation required
• Withstands high hydrostatic pressures
• Hydraulic set for low hydrostatic head wells
• Locked in pack-off force
• No mandrel movement during setting
• Straight pull or optional rotational release
• Hydraulic hold-down for differential pressure from below

Setting procedure:-
The Model ―WC-HP-1‖ Hydrostatic/Hydraulic Packer is set
by pressuring the tubing to obtain a differential at the
packer. To accomplish this a means of temporarily plugging
the tubing below the packer must be provided.
Example: Run a WELLCARE Hydro-Trip Pressure
Sub, below the ―WC-HP-1‖ Hydrostatic/Hydraulic Packer
or a WELLCARE Flow Control Seating Nipple installed at MODEL: WC-HP-1

If more than one ―WC-HP-1‖
Hydrostatic/Hydraulic Packer is to be run, place the tubing
plugging device below the lowest packer. When the tubing
is pressured in this case, all of the hydrostatic packers will
be set simultaneously. If it is desirable to individually set
and test each packer, the Model ―WC-HP-1‖
Hydrostatic/Hydraulic Packer is adaptable to individual
setting and testing by a simple adjustment of shear screws in
the segment retainer housing. Dress the lowest packer with
two brass shear screws. When dressing packers for this type
hook-up, all packers going on one string should be dressed
with shear screws from one box to ensure similarity of shear
values. Dress the second (middle packer in three-packer
hookups, or upper in two-packer hookups) with five brass
shear screws, and a third (upper) packer with eight brass
shear screws. This allows the packer to be set individually.
The first will set with approximately 1,000, the second
2,000 and the third 3,000 psi differential at the packer. In
order to test the packers individually, a means of temporary
communication between the tubing and the casing (i.e. a
Sliding Sleeve below each packer) will be necessary. The

Hydraulic Set High Pressure High Angle
Production Packer:-
Model : WC-HP-3
Prod. No. WC-20105
The Model ―WC-HP-3‖ is a pure 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 Wire
line Set Packers.

Features/Benefits:-
 No tubing movement is required for setting the
Packer. This allows the well to be kept positively
controlled at all times because the tubing is landed
before circulating or displacing well fluids prior to
setting the packer. Two or more packers can be set
together or in any desired sequence.
 The ―WC-HP-3‖ Packer design features four bi- MODEL : WC-HP-3
directional, single piece slips located below a three PRODUCT NO. WC-20105
element packing system consisting of dual
durometer rubber elements. The slips are fully
enclosed in a shear pinned slip housing which is
protected by a full diameter guide located below
the slip housing.
 Two balanced pistons are utilized during the
setting of the Packer. The lower piston moves
down to set and anchor the slips while the upper
piston moves upward to compress the packing
element. This action imparts the entire setting force
to both slips and packing thus assuring a positive
anchor and pack-off. The pack-off is retained by a
tapered single ratchet ring that locks in and stores
the setting force applied to both the slips and
packing element.
 The ―WC-HP-3‖ Packer incorporates two methods
of release. Straight pull or rotation. Both methods
are done by the same releasing nut which is located
at the upper end of the Packer. Straight pull release
is accomplished by shearing retaining screws of a
predetermined quantity which frees the tubing.
Rotation release is accomplished by approximately
eight right hand turns of the Tubing which also
frees the Packer. Straight pull is then applied to
completely relax the Packer for retrieval. An
equalizing valve is also located in the releasing
portion. The positive acting valve is automatically SPECIFICATION DATA

Fully Hydraulic Set Large Bore
Production Packer:-
Model :WC-HPL-4
Prod. No. WC-20103
Model ―WC-HLP-4‖ Retrievable Packer is fully
Hydraulic set large bore production packer, used for
production, zone isolation, multiple string completions,
combining hook ups and for stimulation.

The setting starts on application of pump pressure
to the tubing. The ―WC-HLP-4‖ sets and packs-off due to
the force applied by tubing pressures. The design of the
setting mechanism ensures sustained pack-off force
throughout the life of the Packer. Opposed Double Grip MODEL: WC-HPL-4
slips prevent movement of the Packer in either direction due PRODUCT NO. WC-20103
to pressure differentials, while allowing landing of the
tubing in tension, compression, or neutral.
The standard model ―WC-HLP-4‖ Packer is
equipped with Shear Screws for a straight pickup release.
The Packer is suitable for maximum 6,000 psi differential
pressure.

Features:-

 No Tubing Manipulation required: The setting
mechanism of this Packer is activated with pump
pressure. The Packer can be set after the well is
flanged up and the tubing is displaced.
 Setting Mechanism: The design of the setting
mechanism ensures sustained pack-off force
throughout life of the Packer. The tool does not
depend on trapped hydraulic pressure, but
mechanically locks initial setting forces into the
packing elements. Setting activation pressure can
be adjusted by dressing up with required number of
Shear Screws.
 Opposed: Double grip slips prevent movement of
the Packer in either direction due to pressure
differentials.
 Unloader valve: Provided for equalising the
pressure to nullify the swabbing of the Packing

It is ideal for use in deviated wells, multiple-packer
completions, and applications where the packer is to be set
after the wellhead is installed. Because no mandrel
movement occurs during setting, the WC-HP-6 Packer may
also be used in multiple-packer completions where all
packers are set simultaneously.
Set with a pressure differential, the WC-HP-6
packer has an easily adjustable setting-pressure feature and
a bidirectional mechanical slip system. The packer features MODEL: WC-HP-6
a unique design that allows debris to be circulated from
above the packer when releasing. A three-piece, dual-
durometer element system and a built-in equalizing and
circulating system ensure reduced risk and easy release.
No tubing movement is required to set the packer.
After the packer is set, the tubing can be landed in either
compression or neutral condition. The setting force is
mechanically locked into the sealing elements with a
positive ratchet-lock mechanism. The WC-HP-6 retrievable
packer is released with and upward pull exceeding the
rating of the shear release screws. Optionally, the WC-HP-6
packer is available with a rotation release mechanism.

Hydraulic Set Retrievable Packer:-
Model :WC-HP-7
The Model WC-HP-7 Hydraulic-Set Retrievable
Packer is a single-string packer ideal for use in wells where
mechanical-set packers might experience difficulty in
running, setting, or retrieving. It can be used in single-
packer installations, as a lower packer in multiple-string
completions, or in tandem for single-string, selective,
multiple-zone completions.
The Model WC-HP-7 Packer can be used when
displacing and setting is desirable after the well is flanged-
up.

Features:-
 Mechanicl/Hydraulic-set, no rotation or
reciprocation required: tubing may be displaced,
well flanged-up, before packer is set
 Optional releasing methods: can be released by
either straight pull or right-hand rotation
 Mechanically locked in set position: holds
differential pressure from above or below without
hydraulic hold-down buttons. Locking piston and MODEL : WC-HP-7
collet prevent pressure generated piston forces PRODUCT NO.WC-20109
from acting on release shear screws during
production or treating
 Multiple element packing element system: two
hard, outer packing elements and a softer inner
packing element assure positive pack-off over a
wide range of well conditions
 Caged slips: reduce problems while running and
retrieving
 One-piece mandrel through packer
 Rated for 6,000 psi at 300°F

Application:-
 Run as single packer
 Run as the lower packer in multiple-string
completions
 Run in tandem for selective, multiple-zone
completions
 Run when displacing and setting is desirable after
well is flanged-up

16

Setting procedure:-
The Model WC-HP-7 Packer is run to the desired
setting depth on the tubing string.
The well may be flanged-up and the tubing displaced. While
displacing the tubing, rate must not exceed 3 bbl/min to
prevent damage to packing element. Apply 2,500 psi
differential pressure at the packer against a temporary
tubing plug installed below the packer.
Pressure applied to the tubing enters the piston
area, compressing the packing element and settings the
slips. As the slips grip the casing wall to prevent movement
of the packer, body lock rings are set to mechanically hold
the setting force in the packer until it is released.

Releasing procedure:-
The Model WC-HP-7 Packer is released by right-
hand rotation or straight pick-up. Either tension pulled at the
packer in excess of the shear screw values, or right-hand
rotation: releases the tie bar mandrel from the packing
element mandrel, opens
a circulating port above the packing element, and allows the
packer to be removed by continued upward movement of
the tubing.

Hydraulic Set Dual Bore Production
Packer:-
Model : WC-HP-9
The Model WC-HP-9 is a hydraulically set,
mechanical dual string production packer.
The WC-HP-9 is available with short or long string
setting capabilities and a variety of tubing connections. The
packer has been carefully designed for maximum flexibility
when it comes to submersible pump applications. By
changing only a few parts, the WC-HP-9
can be modified from a high-pressure production packer to
a packer installation for submersible pumps.
The WC-HP-9 has a patented sequential upper slip
releasing system that is designed so that each slip is released
individually to reduce the pull required to release the
packer. The angles on the slips, cone, and the upper slip
body results in releasing forces which allows the penetration
of the slips to release smoothly from the casing.

Application:-
Normally run above a single string hydraulic or
wireline set seal bore packer.
The short length of the WC-HP-9 makes it ideally MODEL : WC-HP-9
suited for deviated wells or doglegs. PRODUCT NO. WC-20111
Also, since there is no tubing manipulation
required to set the packer, the wellhead can be installed and
flanged up before setting the packer.

Features:-
 Short, compact and economical
 No hydraulic hold down buttons
 Shear release easily adjusted
 Sequential upper slip system for easy release
 Setting cylinder below elements to eliminate all of
the critical o-rings after setting
 Hydraulic set to allow flanging-up before setting
packer
 Differential pressures help to improve the rubber
pack-off
 Can be pressure tested on location
 Multiple bores available for control line, ESP
cable, chemical injection line, and well monitoring
devices
 Three seal options for the short string; J-latch,
locator, or snap latch

19

Setting Procedure:-
The WC-HP-9 is set by temporarily plugging the
long string and pressuring the tubing.
When tubing pressure is applied to the packer, the
inlet port allows pressure differential to be present in the
setting chamber. This differential forces the setting cylinder
down and sets the lower slips. The setting mandrel is forced
up, and sets the upper slips and packs-off the elements. Any
relative motion between the setting cylinder and the setting
mandrel is held in place by the locking nut, which will
ratchet in only one direction. With a pressure differential
from above, the force is transferred through the outer
components of the packer and is supported by the lower
slips. With pressure differential from below the force
transfers through the outer components of the packer and is
supported by the upper slips.

Releasing Procedure:-
The WC-HP-9 is released by a straight pick-up on
the long string. The shear release value is adjustable.

SPECIFICATION WC-HP-9

Hydro Trip Pressure Sub:-
Model : WC-HTS
Hydro Trip Pressure Sub (WC-HTS) is installed in
the tubing string below a hydraulically actuated tool such as
a hydraulic packer to provide a method of applying the
tubing pressure required to activate the tool.
To set a hydrostatic packer, a ball is circulated
through the tubing and packer to the seat in the Hydro-Trip
Pressure Sub, and sufficient tubing pressure is applied to
activate the setting mechanism in the packer. After the
packer is set, a pressure increase to shear screws to allow
the ball seat to move down until the fingers snap back into a
groove. The sub is then full opening, and the ball passes on
down the tubing.

Auto Fill Pump Out Plug:-
Model : WC-POP-A (WC-20124)
The Model ―WC-POP-A‖ is used as a tubing Plug
device against which pressure can be applied in order to set
Hydraulic Set Packers. The Pump out Ball Seat Sub is made
up in the tail pipe below the Packer to be set. In this model
with the ball seating down, the Pump out Plug acts as a
reverse check valve preventing flow down the string, while
allowing the string to fill form below. Without need to drop
a ball to seat, the tubing can be pressured up. Once the
Packer is set, tubing pressure is increased to values shown in
the chart below to shear the screws holding the ball seat sub.
The ball seat and the ball with spring etc. are blown out of
the sub to the bottom of the well. Any tubing run below the
ball seat sub should have sufficient ID clearance to permit
passage of the ball, ball seat, spring etc.

Pump Out Plug With Half Mule:-
Model :WC-POP-H (WC-20125)
The Pump-Out Plug Ball Seat Sub, has been used
as a tubing plugging device against which pressure may be
applied in order to set the Packers. The Pump-Out Ball Seat
Sub is made up in the tail pipe below the packer and a
trapping ball is dropped through the packer to its seat in the
sub. Pressure is then applied to seat the packer . Once the
packer is set, tubing pressure is increased to values as shown
in the chart below to shear the screws holding the ball seat in
the sub. The ball and ball seat are blown out of the sub to the
bottom of the well. Any tubing run below The Ball Seat Sub
should have sufficient ID clearance to permit passage of the
ball and ball seat.

Lok-Set Mechanical Retrievable Double
Grip Packer:-
Model: WC-MECH-3 & WC-MECH-3L
Product No.WC-20905 & WC-20906
The Model ―WC-MECH-3‖ is a general purpose
packer for production, injection, zone isolation, or remedial
operations. It holds pressure from above or below while
allowing the tubing to be placed in tension, compression, or
in a neutral condition. The ―WC-MECH-3‖ is a Full-Bore
Double-Grip Retrievable Packer with an integral Unloader.
Opposed, non-transferring dovetail Slips prevent movement
of the Packer in either direction due to pressure differentials,
while allowing landing of the tubing in tension,
compression, or neutral. The Lock segments serve as a
releasable Lock Ring to maintain pack-off once the packer is

Model: WC-MECH-4
Product No.WC-20907
The model ―WC-MECH-4‖ is a Mechanical Set,
Double grip Retrievable Production Packer for medium to
high Pressure application.
The Packer allows unrestricted flow and passage of
full gauge wire line tools and accessories with an
unrestricted ID, making it ideal for zone isolation injection
and production applications.
It can be set with production tubing in tension,
compression or neutral maximizing effectiveness in shallow
wells or fiberglass tubing operation. The packer’s
mechanical lock-set action closes an internal bypass and
allows application of pressure above or below the packer.
The packer is released by a ¼ right-hand turn at
the tool, followed by straight pickup of the production
tubing.
Optional emergency release feature is also
available on request.

Compression Set Retrievable Packer:-
Model: WC-MECH-5
Product No.WC-20908
Compression Set Retrievable Packer is high
pressure, full opening, compression set tools for squeeze
cementing, acidizing, fracturing and other stimulation
procedures. This tools features a pressure balanced unloader
that closes when the packer sets. While pressure aids in
maintaining the seal, the unloader can be easily opened
under high differential pressure. The large internal by-pass
reduces swabbing when running and retrieving.

Special features:-
 Large internal by-pass.
 Built in pressure-balanced unloader.
 1/4 turn set-straight pick up release (standard).
 Equalizing ports directly above elements. MODEL: WC-MECH-5
 Additional J-slot arrangements available. PROD.NO. WC-20908

Snap Set Compression Packer
With Hold Down & Without Hold Down:-
Model: WC-MECH-6H & WC-MECH-6
Product No.WC-20909 & WC-20910
Snap Set Compression Packer without hold down
and Snap Set Compression Packer with hold down are
retrievable set down packers featuring a bypass area through
the packer and an integral unloaded. They are used as an
upper packer in a single string two packer installation, for
zone isolation, injection or production.
Packers are used above either retainer production
packers or retrievable packers.

Features:-
 Multiple packing element system proven on the
Model WC-MECH-2 .
 Operation of the packer is simple. No tubing
rotation is required.
 A collate-type snap-latch prevents the packer from
setting before landing the seal assembly or before
setting a lower retrievable packer. Lower portion
of the tool is rotationally locked to deliver torque
in either direction through the packer.

Setting Procedure:-
To set packer above a retrievable packer:
Make up both packers in the tubing string and run
them in the well. Rotate the tubing to prepare the lower
packer for setting. Apply 6,000 lbs. to 8,000 lbs., set-down
weight, depending on packing element hardness, to set and
pack-off both packers.

To set packer above a seal bore packer:
Run and set a Seal Bore Packer. Make up the
Snap-Set Packer at the desired location in the tubing string
above the tubing seal assembly. Run the string in the hole
until the locator sub on the tubing seal assembly is landed in With Hold Down Without Hold Down
the Seal Bore Packer. Apply set-down weight of 6,000 lbs.
to 8,000 lbs., depending on packing element hardness, to set
and pack-off the packer. The set-down weight trips the
snap-latch mechanism and packs-off the packing elements.

To release the packer simply pick up the tubing
string. If the weight of the string below the packer is greater
than 1,500 lbs, the snap-latch will relock to the running-in
position. The packer can then be raised or lowered during
the retrieving operation.
If the weight of the string below the packer is less than
1,500 lbs, the snap-latch will not relock, so the assembly
must be brought to the surface before attempting to run it
again.

Tension Set Packer:-
Model: WC-TP
Product No.WC-20904
Tension packer is compact, economical retrievable
packer, primarily used in waterflood applications, this
packer can also be used for production and/or treating
operations. It is used where a set down packer is
impractical. Because the tension set, it is ideally suited for
shallow wells where set down weight is not available.

Application:-
Waterflood, shallow or low fluid level wells with
insufficient tubing weight to set compression packers.

Features:-
 Compact
 J-slot control for normal set and release
 Shear ring secondary release
 Right-hand emergency release MODEL :WC-TP
 Rocker type slips PROD. NO. WC-20904
 Inexpensive

Setting Procedure:-
Run the packer to desired setting depth, making the
last movement downward. Rotate the tubing to the left 1/4
turn at the tool. Pick-up tubing to apply desired tension and
maintain pack-off.

Lower the tubing at least one foot more than is
needed to remove applied tension so that the J-pin will
move fully to the top of the J-slot. Rotate the tubing to the
right 1/4 turn at the packer so slips will now be in the
running position. Packer can be moved to a new position
and reset or it can be retrieved.
As an alternate release method, the packer has shear rings
designed to part at tension varying from 13,000-100,000 lb.
The cone, packing element and guide drop down and are
carried out of the hole by the bottom sub. If normal release
is not possible, left-hand square threads on the top sub of
the packer allows the tubing to be retrieved when the packer
will not otherwise release.
