Material Selection
Wellcare equipment is offered in various material
configurations for a variety of well conditions.
Wellcare employs leaders in the field of
metallurgy and polymer chemistry to ensure
superior material recommendations are made to
our customers.
For corrosive wells, Wellcare corrosion
metallurgists and polymer scientists are available
to provide expert material recommendations. To
provide the most cost-effective recommendations,
the well environment data form has been
developed to aid in gathering the necessary well
data.
The following alloys and groups of alloys
are currently the most common materials used for
the construction of packers and related
equipment:
Standard, non-corrosive service–low alloy
steels (e.g. 4140) with mechanical
properties compatible with API P110
tubular.
Non-corrosive service containing H2S–
low alloy steels (e.g. NACE MR0175
compliant 4140) with mechanical
properties compatible with API L80
tubulars.
Corrosive CO2 service with little or no
H2S–Martensitic and PH stainless steels
(e.g. 9Cr, 13Cr, 17-4PH, alloy 450, Super
13Cr) with mechanical properties that vary
from 80 ksi to 110 ksi minimum yield
strength; the selection of the specific
corrosion-resistant alloy(s) depends on the
environment (pH, chlorides, temperature,
H2S, etc.,) and strength requirements
Severely corrosive CO2 and H2S–nickel
alloys such as 825, 925 and 718 at strength
levels of 110 ksi minimum yield strength
and higher.
Severely corrosive CO2, H2S and free
sulphur–nickel alloys such as 625 Plus,
725 and, less frequently, C-276 at strength
levels of 120 ksi minimum yield strength
and higher
For equipment required to perform a temporary
function and then allow quick removal by drilling
or milling, an additional group of materials is
used:
Cast iron
Reinforced polymer-based composites
Besides the more common materials, Wellcare
manufactures packers and related equipment from
other materials when raw material availability,
quantities, delivery schedules, etc., permit.
Example alloys include 316L austenitic, 22 Cr
duplex, 25 Cr duplex, 25 Cr super duplex, alloy
20Cb3, 28 Cr super austenitic, K-500 Monel,
alloy 2025, alloy 2535, alloy 2550, alloy G-3 and
others

Elastomer Selection
Ideally, seal materials have high strength
and resiliency, and remain unaffected by
thermal or chemical environments.
However, there is no single material that
offers adequate levels of these
characteristics for all downhole
applications. Effective sealing in downhole
environments often requires a combination
of materials to form a seal system. Several
sets of identical seal systems can be
combined to create a seal stack with
redundant seals. Choosing the optimum
seal stack requires knowledge of the
application and downhole conditions.
Bonded seals are used in applications that
require seals to be repeatedly inserted into
and removed from the sealbore while
holding differential pressure. This action is
known as unloading. Bonded seals are
composed of high-strength elastomers,
usually nitrile or Viton™, which have
limited operational capabilities.
Applications beyond the capabilities of
bonded seals require more inert
elastomers. Generally, these premium
elastomeric materials have lower
resistance to extrusion than nitrile or
Viton* and require the protection of a
containment system to prevent failures.
Sealing systems using contained premium
elastomers are offered as a chevron- or v-
ring-type seal stack.
V-ring seal stacks can tolerate movement
while holding high pressures, providing
they are always contained within a
sealbore. Therefore, while holding
differential pressure, they must remain in
the sealbore. Selecting the most
appropriate seal stack can be simplified by
referring to the seal stack service matrix
shown below.
Selecting the most appropriate seal stack
can be simplified by referring to the seal
stack service matrix shown below. For

Packer Performance Definition
The successful performance of any packer
includes recognizing that the combined
effects of varying differential pressure or
applied forces cannot be considered
independently. Rating a production packer
in terms of differential pressure alone does
not sufficiently describe the packer's
performance limits. To accurately measure
and compare the performance of various
packers, an understanding of the
simultaneous effects of differential
pressure and axial loading is required.
Wellcare has developed a high-tech R&D
center which is industry's first means of
describing a packer's performance
capabilities, under all possible cyclic
loading, temperature, pressure &
circulation conditions.
The analytical system combines computer
modeling, sophisticated numerical
stimulation techniques, including finite
element analysis, exhaustive laboratory
testing, and field verification.
To apply this technology, a graphical
solution is used to provide an accurate and
useful definition of a packer's safe
operating region.
Wellcare incorporates API Quality
Management System of level Q1 with
100% inspection and testing of material,
component and products, so as to render
best customer satisfaction.
The numerical controlled system of
graphical representation and recorded
tabular data system in accordance with
API 11 D1 (of level V3 as of now but
trending up to V0), is used to validate
permanent and retrievable packers are
compatible with the demands of today's
critical completions. Ensuring all load
combinations fall inside the region formed
by the curves confirms that the equipment
is adequate for the combined loading
conditions. This area is called the ―safe
performance envelope‖ In those instances
where one or more sets of loading
conditions fall outside the safe
performance envelope, a detailed
evaluation of all aspects of the proposed
completion system is required to upgrade
its performance. Some conditions outside
the safe performance envelope adversely
affect the packer’s ability to maintain its
sealing integrity. Others may prevent the
packer from functioning as designed,
while retaining pressure integrity. For
more information regarding testing and
simulation, testing and validation system
of packers, contact your local Wellcare
Representative.

Hydraulic Set Production Packer:-
Model: WC-HP-1& WC-HPL-1
Prod.no. WC-20101 & WC-20112 The Model ―WC-HP-1‖ is a hydrostatic and/or
hydraulic set packer that allows the tubing to be left in a
compression or neutral condition. The Model WC-HPL-1
Hydrostatic Packer is a large bore version of the WC-HP-1
Packer. Features, advantages, and operational procedures
are basically the same as those described for the WC-HP-1.
Application:- Used in multi-zone production where crooked or deviated
holes are not suitable for mechanical packers. An
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
some point below the packer, with a Blanking Plug run and
retrieved by standard wireline techniques. Wireline Re-
Entry Guide with Pump-Out Plug or Ball Seat can also be
used to blank off tubing.
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
lower packer can be set and tested down the casing. The
second packer can then be set, the sleeve below it opened,
and the second packer tested down the casing. The third
packer is set and tested the same way. It is recommended
that a blanking plug be used to temporarily plug the tubing
for setting the packers because of the higher setting
pressures.
Releasing procedure:- The standard ―WC-HP-1‖ Hydrostatic/Hydraulic
Packer is equipped with 30,000 lb. shear ring for a straight
upstrain release. Other shear values are available in 20,000
to 50,000 lb. for all sizes 5-1/2 thru 9-5/8.

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-
directional, single 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 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
opened during the releasing procedure to equalize
pressure and allow circulation between the annulus
and Tubing. In addition, a large diameter by-pass
area is located inside the packing mandrel which
allows fluid passage for rapid retrieving while
reducing element swabbing.

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
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 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
element.
Multiple: Packing element system.

Model: WC-HP-6
Product No. WC-20106
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
a unique design that allows debris to be circulated from

Hydraulic Set Retrievable Packer:-
Model :WC-HP-7
Product No. WC-20109
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
collet prevent pressure generated piston forces
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
MODEL : WC-HP-7
PRODUCT NO.WC-20109
WELLCARE OIL TOOLS PVT LTD
17
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
Product No. WC-20111 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
suited for deviated wells or doglegs.
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
MODEL : WC-HP-9
PRODUCT NO. WC-20111
WELLCARE OIL TOOLS PVT LTD
20
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.

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

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
set, and locks the Unloader in the closed position until the
tool is released. The split Lock and Control Segments allow
the tool to be both set and released with right-hand rotation.
The Retrievable Lok-Set Packers are compression set
retrievable packers that allow the tubing to be left in a
tension, compression, or neutral condition.
Applications:- most production, injection and zone isolation
operations.
Features:- Internal by-pass
Opposed dovetail slips positive set
Holds pressure from above or below
Can leave tubing in a tension, compression or
neutral condition
Right hand rotation sets and releases the packer
Retracted dovetail slips
Converts to mechanical bridge plug with the
addition of a valve
Optional packing element systems
Parts interchangeable with other manufacturers
Note:-The WC-MECH-3L Lok-Set is similar to the
WC-MECH-3 and is recommended when a larger-than-
normal bore through the packer is required.
MODEL: WC-MECH-3
PROD.NO. WC-20905
Setting procedure:-
Hang the WC-MECH-3 packer to completely
stretch it out before starting in the hole. Immediately prior
to running in, rotate the drag block housing sub-assembly
several turns to the left to make sure the segments are
functioning properly. Do not rotate the drag block housing
sub-assembly to the right as this will bind the control
segments and prevent them from moving after reaching
setting depth.
Upon reaching setting depth, slowly lower the
packer while rotating the tubing (approximately 2 turns
right at the tool) until the packer takes weight. Set-down a
minimum of 6,000 lbs. to initially set the upper slips.
Lowering of the tool must take place while rotating for the
tool to set properly.
WELLCARE OIL TOOLS PVT LTD
30
To fully engage the lower slips, apply an upstrain (10,000 to
20,000 lbs. for sizes 4.1/2 thru 5.1/2 and 7 and 7.5/8 )
against the tool. When the tubing is to be landed in tension,
a strain greater than the landing strain should be applied
during the setting operation.
To completely set upper slips and pack-off the
packing element system apply set-down weight (6,000 lbs,
for sizes 4.1/2 thru 5.1/2 , 10,000 lbs. for size 7 and 7.5/8 ).
If sufficient set-down weight is not available, such as in
very shallow wells, the tool can be set and packed-off by
left-hand rotation.
The tubing may now be hung in tension,
compression or neutral.
Releasing procedure:-
Apply an upstrain of approximately 3,000 to 6,000
lbs. and rotate the tubing (four to eight turns at the tool) to
the right until the tool moves up the hole. When releasing
the packer with pressure in favor of the tubing, rotate tubing
to the right slowly
enough to equalize before the lower slips disengage.
Continue to rotate to the right several turns while
moving up the hole to be certain the slips are fully
retracted.

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
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.
Releasing Procedure:- 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.

weight of the tubing.
Lubricate the polished bore.
Install the test pins in the corresponding holes keep
them in place with a heavy duty elastic band or
adhesive strip.
Pressurize the assembly make sure that all air is
eliminated. Remove test plugs and all test pins.
Lower the packer slowly to the position. Be careful
when entering liners.
Install and land tubing Hanger.
Test the tubing by running (remaining attached to)
a Standing valve in a nipple above the Packer.
Install the well head.
Displace the mud with a ―completion‖ fluid in the
annulus by introducing a lighter fluid (diesel/gas
oil) for example into the tubing.
Setting Procedure:-
The Packer is run in the model ―WC-W‖ wire line
adapter kit. Attached to the model ―WC-HST‖
Hydraulic Setting Tool on the drill pipe and lower
to setting depth.
The tubing fits automatically as it is run in, though
a ported top sub in the setting assembly.
The port also permit circulation at any time.
A 1-7/16‖ Brass Ball is pumped down to seat in the
hydraulic setting tool.
Approximately 1500 psi is applied to set the packer
slips. Following which the pressure is released and
or tension applied to shear the Release stud of the
Wire line Adapter Kit. The hydraulic setting Tool
along with Wire line adapter kit can then be
retrieved leaving the packer set in hole.
Retrieving Procedure:- 1. Run the ―WC-RT‖ Retrieving Tool on the work
string or the tubing.
2. Put Set down weight 3000-5000 Lbs on the Packer,
may be slickly rotated to the right to engage the
collate of the Retrieving Tool under the supporting
sleeve of the Packer.
3. PULL ! In principle the packer should release with
a pull of 5-10tons. In order to fully retrieve the
Packer up-ward and down ward motion of
retrieving string will help. Once the screws have
sheared the support sleeve moves upwards freeing
the support beneath the finger of the collet. The
latter can then flex and detach itself from the
Housing. On upward movement of the body of the
packer the compression of the packing element is
released and the slips retracted. The Setting Sleeve
is supported by the Ring witch rests on the top of
the piston above the o-ring.

temporary bridge plug.
The standard version of the Wire Line Set Drillable
Permanent Production Packer has a 70 hard nitrile packing
element and is rated at 10,000 psi differential pressure up to
300…F. For bottom hole temperatures between 200…F and
400…F, a 90 hard packing element should be specified.
Also available when specified is a steel body heat treated to
30-36Rc which will give the packer a 12,000 psi differential
pressure rating.
Features/benefits:- Proven reliability
Slim-lined
Solid construction that makes possible a significant
savings in rig time by providing a faster run-in
without fear of impact damage or premature setting
Two opposed sets of full-circle, full-strength slips
A packing element that resists swab off but packs
off securely when the packer is set
A smooth, continuous ID sealing bore
Unique Interlocked expandable metal back-up
rings that contact the casing creating a positive
packing element extrusion barrier
Operation:- The proper size wireline adapter kit is installed in the
packer. The packer and adapter kit are then connected to the
pressure setting assembly. These are run to setting depth on
the electric wireline.
A small charge of electrical current, transmitted
through the electric wireline, ignites the power charge in the
setting assembly, gradually building up gas pressure. This
pressure provides the controlled force necessary to set the
packer. When the prescribed setting force has been applied
to the packer, the release stud in the wireline adapter kit
parts thus freeing the setting equipment from the packer,
allowing it to then be retrieved. The proper release stud is
shipped with each packer.

Splined Expansion Joint:-
Model : WC-SEP
Product No. WC-22203 Splined Expansion Joint is designed to be used in
single and dual string completions to accommodate changes
in tubing length caused by variations in temperature. They
are capable of maintaining the pressure integrity of the
tubing while allowing the string to safely expand and
contract, and can be run above rotational release or straight
pickup release packers.
It may be shear pinned at one-foot intervals along
its entries stroke length, allowing the operator to select the
proper expansion and/or contraction stroke that will be
required after the splined expansion joint has been installed.
The splines allow for torque through the joint.
Features:-
Rotationally locked at all times for transmitting
torque when required.
Multi-spline design for high torque load.
Maximized tension carrying capability.
ID compatible with tubing ID.
Tool can be pinned at one foot spacing from closed
to fully stroked position.
Shear value can be adjusted by varying the number
of shear screws.
Torsional Rating 7,500 ft-lb Standard Service
application at 110,000 psi material yield. 5,500 ft-lb
for Sour Service application at 80,000 psi material
yield.
Pressure rating 7,500 psi for Standard Service
application at 110,000 psi material yield.
5,000 psi for Sour Service application at 80,000 psi
material.
Operation:- It is pinned and run in the closed or partially
extended position. When allowing for thermal expansion,
the splined expansion joint is shear pinned in the fully
extended position. If it is made up on the production string
for the purpose of allowing for thermal expansion, and is
being run above a hydraulic set packer, then the shear value
of the shear pins must be sufficient to accommodate the
proper setting of the packer without prematurely shearing
the expansion joint. Used on a production string that must
land in a permanent packer, the shear pins must have
sufficient shear resistance so that the expansion joint will
not inadvertently close when the packer stinger is landed
and engaged.

Product No. WC-21201 The Model WC-HST Hydraulic Setting Tool is
used to hydraulically set the packers on tubing or drill pipe.
Application:- Particularly useful for setting packers in deviated
wells or wells where it is difficult to get down hole with a
wire line set packer.
Features:- Tubing conveyed
Can push tools to bottom in deep or deviated wells
Tubing will fill and drain automatically
Setting Tool can be tested from above after setting
the packer
Well can be circulated from above after setting the
packer
Setting pressure may be adjusted by varying the
number of shear pins
Setting Procedure:- When setting the Packers, sufficient pressure must
be applied to set the upper slips which is applied to the
tubing. Tension is then pulled for final pack-off and setting
of the packer.
When setting the Packer, sufficient pressure must
be applied to set the slips, pack-off the element, and shear-
out of the packer, if drive-loc pins are used.
The tubing may be allowed to fill as the packer is
lowered and then a ball dropped to plug off the tubing.
Pressure is then applied to the tubing activating the
chambers of the Hydraulic Setting Tool.
In order to apply the proper setting force to the
packer, both hydrostatic and pump pressure must be
considered. Please consult a Wellcare Technician or refer to
the Hydraulic Setting Tool tech documentation to calculate
proper setting force.
Releasing Procedure:- Rotational
Bleed pressure off of tubing. Before attempting to release
the Hydraulic Setting Tool and Adapter Kit from the packer,
consideration must be given to the pressures acting on the
tools. Balance the forces so that a slight up strain remains.
Rotate to the right six to eight turns while holding the up
strain to release from the packer.
Shear
The Hydraulic Setting Tool will automatically release from
the tool when sufficient force is applied.

Tubing Anchor Catcher:-
Model: WC-TAC
Product No. WC-22502 The Tubing Anchor Catcher is a rugged, compact,
mechanical tool that anchors tubing in tension, holding it
stationary during pump strokes. The anchor also holds the
tubing stationary should it part. Anchoring the tubing
prevents it from buckling and breathing. This increases
pumping efficiency while reducing rod, tubing, and casing
wear. When properly set, there is no slip movement to cause
casing damage. Unlike other anchor catchers, this tool can
be lowered down hole after emergency shear out without
resetting slips.
Applications:- Anchor the tubing string in tension or compression
in wells of any depth. This prevents movement of the tubing
string during pumping operation, thus increasing pump
efficiency and decreasing rod wear.
Features:- Drag springs protect slips during run-in
Sets in tension or compression
Ample area for gas migration around anchor
Rotational or shear release
Tool may be rotationally released and reset
Drag springs and shear pins are easily replaced in
the field
Setting Procedure:- The Anchor Catcher is installed on tubing, usually
above or below a pump.
Anchor is run to depth, and the tubing is rotated left
to set. Casing weight determines number of turns required.
Pick-up on tubing to check setting of slips. Pull desired
tension on anchor to check spacing.
CAUTION: Do not overstretch tubing, as this may tend to
shear release anchor catcher.
Releasing Procedure:- Remove tension from tool. Rotate tubing to the
right until anchor releases. If the anchor does not release
normally, a straight pull will shear the pins allowing the
anchor to be removed from the well.

Hydraulic Set Tubing Anchor Catcher:-
Model: WC-HTAC
Product No. WC-22503 The Hydraulic Set Tubing Anchor Catcher is a
pressure actuated, fully retrievable anchor catcher designed
to hold the tubing string in tension or compression.
No tubing manipulation is required in order to set
the anchor. Once set, bi-directional slips anchor the tubing to
prevent upward or downward movement during rod
pumping and to prevent tubing from falling should it part.
Applying tubing pressure against a temporary tubing plug
run below the anchor catcher sets the anchor catcher. The
anchor catcher is released by pulling sufficient force to shear
the release screws. The number (up to 12) predetermines the
shear value (4,000 lb. each) of the releasing mechanism.
Application:- Anchor the tubing string in tension or compression
in wells of any depth. This prevents movement of the tubing
string during pumping operation, thus increasing pump
efficiency and decreasing rod wear.
Features:- Bi-directional slips anchor the tubing to prevent
upward or downward movement
Sets in tension or compression
Increases pump efficiency
Improves operating costs by reducing maintenance
and down time caused by tubing or sucker rod wear
Setting Procedure:- Run anchor catcher to desired depth and space out
completion using normal procedures.
If an expendable seating sub is used to temporarily
plug the tubing, drop the bronze setting ball. Allow
substantial time for the ball to gravitate to the ball seat.
CAUTION: Do not pump ball into place. Pressure up on the
tubing to 1,200 psi minimum above hydrostatic pressure at
the anchor. Increase the pressure to the shear value
necessary to pump out the ball seat.
Releasing Procedure:- To release the Hydraulic Set Anchor Catcher, pull
tension on the tubing until the predetermined value of the
shear pins is applied at the tool and the pins shear. The tool
may then be retrieved from the wellbore.

Product No. WC-22504 It is a right hand set tool which acts as a tubing
anchor to maintain tension in the tubing string and as a
tubing catcher to prevent parted pipe from falling to the
bottom of the well.
Applications:- To completions using Progressive Cavity Pump
systems.
Features:- Provides no-turn feature for Progressive Cavity
Pump operations
Increases pump efficiency and helps prevent the
tubing from backing off
Rotate right to set
Optional release straight pull, shear release
(primary), left rotation (secondary)
Setting Procedure:- At the desired setting depth, rotate the tubing to the
right with hand wrenches until the slips contact the casing
(approximately five to eight turns). Maintain right hand
torque while alternately pulling strain and setting down
several times to work all the slack out of the tool.
Releasing Procedure:- An up strain greater than the total shear strength of
the shear pins plus the weight of the tubing should release
the tool. Optional release procedure, with tubing in slight
compression, rotate the tubing to the left (5 to 8 turns at the
tool) to retract the cones from the slips and allow the slips to
move back into the housing. To insure a complete release,
reciprocate the tubing string a few feet while rotating a few
more turns to the left before starting out of the hole.
Caution: Left-hand rotation may back-off tubing.

Casing Scraper:-
Model: WC-CS
Product No. WC-20701 The Wellcare Casing Scraper is designed to remove scale,
mud cake, cement sheath, embedded bullets, and other
foreign material from the inside of the casing wall.
Maintaining a clean casing I.D. is vital to the efficient
operation of down-hole tools used in drilling the well. The
resulting smooth surface properly prepares the casing for
subsequent down-hole operations such as packer setting and
squeeze tools.
Construction:- Manufactured from alloy steel and heat treated to
provide strength and durability, each scraper must pass rigid
nondestructive testing to ensure the highest quality product.
Each tool has six blades specially aligned on the body to
provide the maximum cutting surface area for vertical and
rotational scraping. The blades are designed to give
optimum shearing action with the least amount of restriction
to returning well fluid. The splined body provides absolute
safety and security by locking each blade onto an integral
part of the scraper. This unique body design also allows for
ease of maintenance and dressing of the tool. All casing
scrapers can be easily set for positive or spring loaded
scraping action. Even when set positive to drift, the spring
loaded design will effectively scrape multi-weighted casing
within the well. All blades are cast steel and heat treated to
provide long lasting service life.
Assembly:- Assembly of the casing scraper is quick and simple
and can easily be done in the field. Secure the tool body. Insert
springs into the blade body drive. Set blade over body splines at
center of tool, compress blade and slide into splines. Install
remaining blades in the same manner. Offset the upper blade set
from the lower set by one spline. Secure blades to body with
split collar ring.

Reverse Circulating Junk Basket:-
Model: WC-RCB
Product No. WC-20702 The Wellcare Reverse Circulating Junk Basket
(WC-RCB) is a junk retrieval tool designed to remove all
types of objects from the bottom of the well bore. This
superior tool removes such items as slips, hand tools, bit
cones, and any other small pieces of junk from the well. The
WC-RCB uses reverse circulation to aid junk recovery.
Construction:- The tool consists of a top sub, barrel assembly,
catcher, and shoe. The barrel assembly consists of an inner
and outer barrel, valve seat, cup, and ball. A lift sub is also
provided to assist in handling.
Assembly and Operation:- Make up the junk basket to the bottom of the string
and run into the hole. When the tool is approximately 10 feet
from the bottom of the hole, the ball is dropped down the
drill pipe. The ball will position itself in the ball seat and
reverse circulation will begin. Circulate and begin coring.
Combined with the reverse circulation, this
guarantees that any junk on the bottom is pumped into the
barrel and caught by the catcher assembly. The tool is
removed from the hole after cutting 10 to 20 inches of core.
Optional Components and Accessories:- Shoes - Four types of shoes are available to fit the Reverse
Circulating Junk Basket.
Type A mill shoe is supplied as standard equipment
with the cutting teeth dressed with hard metal and has side
wings. The type A mill shoe is used where the formation is
relatively soft and the fish is a loose piece.
Type B mill shoe is equal in design to the type A
shoe, however, it is hard faced with Wellcare lay a sintered
tungsten carbide in an extremely tough matrix which will
effectively and rapidly mill up junk during the fishing
operation. This shoe will cut on O.D., I.D. and bottom.
Type C mill shoe is also hard faced with Wellcare
lay, however, is designed with a flat bottom, and the
Wellcare lay is placed on the inner face and the outer face.
This design is used to mill up junk and is extremely effective
for cutting cores.
Type B or type C Wellcare lay dressed milling
shoes are used if the formation is hard or if the fish is
embedded in the formation. Use of these two designs also
cuts away protruding excess metal to allow free entry of the
junk into the basket.
Finger Shoe - For retrieving loose junk on the bottom of the
hole which may exceed the maximum catch of the WC-RCB
can be retrieved by use of a finger shoe assembly. The
assembly consists of a shoe extension and the finger
replacement. The entire assembly is used in place of a mill
shoe. The fingers are designed to close in beneath the fish
when slowly lowered during rotation. Finger replacements
can be replaced easily and are very inexpensive.
Magnet Inserts - The WC-RCB can be easily converted to a
fishing magnet by removing the catcher assembly and
replacing it with a magnet insert. The insert still allows
direct or reverse circulation and can be used with A, B or C
type shoes, or special shoes designed to customer
specifications. The magnet insert is the same design as the
Wellcare Fishing Magnet and by adding a top sub to the
magnet insert; it can be used independently as a fishing
magnet.

Core-Type Junk Basket:-
Model: WC-CJB
Product No. WC-20703 The Wellcare Core-Type Junk Basket is a junk
retrieval tool designed to retrieve all types of objects from
the bottom of the well bore. This easy-to-use tool removes
such items as slips, hand tools, and bit cones. The basic
assembly consists of a top sub, barrel, type A mill shoe,
upper and lower catchers.
Assembly and Operation:- Make up the core basket to the bottom of the string
and run it in the hole to a point several feet from the bottom.
With direct circulation, the coring action on the junk
proceeds until a 24 inch core is cut. The fingers in the upper
catcher break the core when an upward strain is applied to
the string. The lower catcher fingers then form a close-
fitting basket that traps the core with its retrieved junk. As in
the other junk basket designs, they are free to revolve within
the shoe, thus eliminating finger breakage.
Optional Components and Accessories:- Three types of milling shoes are available for all core-
type basket systems: Type A shoe with side wings, Type B shoe
with hard-faced Wellcare lay sintered tungsten carbide, and
Type C shoe with flat bottom and Wellcare lay on the inner and
outer faces.
Magnet Inserts – A magnet insert can be used in place of the
catcher assemblies, thus converting the tool to a fishing magnet.
Finger Shoe – A finger shoe is used to retrieve junk that may
be too large to enter the catchers.

Boot Basket (Junk Sub):-
Model: WC-BB
Product No. WC-20705 The Wellcare Boot Basket (Junk Sub) is an
accessory tool used in milling or drilling operations. It is
designed to prevent cuttings that are too heavy to be
circulated from settling to the bottom of the hole.
Construction:- Boot baskets are manufactured from high-strength
heat treated alloy steel to withstand wear. Heavy-duty ribs are
attached to the cup to prevent it from being crushed and to
guide the tool through tight places while tripping out of the
hole. These ribs are not welded to the main body of the tool,
further enhancing its strength.
Assembly and Operation:- Boot baskets are used directly above the mill or drill
bit. On severe milling jobs, it is customary to run two or three
baskets in tandem above the mill. This tandem running not only
increases the capacity to remove the cuttings, but also provides
extra stabilization for the mill. Boot baskets can be run in either
open hole or inside casing. When the basket is working inside a
casing, hard faced pads, dressed to the same O.D. as the mill or
bit, should be used.
Optional Components and Accessories:- The standard boot basket is a welded assembly with a
10 inch deep cup. Long and extra long baskets are available;
these provide a 20 or 30 inch deep cup.

DOWNHOLE FLOW REGULATORS Model: WC-DFJ & WC-DFL
Product No. WC-23501 & WC-23502 The Models WC-DFJ and WC-DFL Downhole Flow Regulators are pressure-compensated flow rate control valves which, when landed in a WC-SND Bypass Ported Seating Nipple, provide a simple, economical, and efficient method for individually regulating volumes injected into multiple zones down one tubing string. The regulators are designed to maintain, regardless of changes in pump and formation pressures, a predetermined fluid injection rate. (however, the minimum required pressure drop of 100 psi across the regulator must be available). Both regulators are compatible with wireline operations and equipment. The WC-DFJ type (with slide throttle) should be used at higher flow rates, while the WC-DFL type (with face throttle), since it is less susceptible to plugging by solids, should be used at lower flow rates. Both present and future flow rates should be considered before selecting which Model to run.

RUNNING TOOL Model: WC-RGTL
Product No. WC-24001 The Model WC-RGTL Running Tool is used to run in and land various types of flow control devices. It has a box down connection for connecting the Model A Shank when required. The tool is run with either a thread protector or locating ring, depending on the application. The tool is dressed with a thread protector for all applications that do not require a No-Go on the tool itself. This includes all running of flow control devices equipped with W and Z , Type Locks. Flow control devices equipped with S Type Locks may be run this way EXCEPT when landing in sliding sleeves. The use of the tool in this application could cause the lock to be positioned in the sliding sleeve rather than in the locking groove. The addition of the proper size locating ring does in effect convert the tool to a No-Go type running tool. This is used when running flow control devices equipped with S type locks for landing in sliding sleeves. It is desirable to use the locating ring whenever running a flow control device equipped with an S Type Lock because the locating ring acts as a positive tool positioner by virtue of the No-Go feature.
