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

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.

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.

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

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.

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.

Tubing Anchor Catcher:-
Model: WC-TAC
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 MODEL: WC-TAC
resetting slips. PROD. NO. WC-22502

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.

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.

place at any desired length (up to 24) and prevent PROD. NO. WC-23002
telescoping or rotational movement.

81

Hydraulic Set Tubing Anchor Catcher:-
Model: WC-HTAC
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 MODEL: WC-HTAC
pumping and to prevent tubing from falling should it part. PROD. NO. WC-22503
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.

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.

82

Right Hand Set Tubing Anchor Catcher:-
Model: WC-RTAC
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. MODEL: WC-RTAC
PROD. NO. WC-22504
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.

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.

83

Casing Scraper:-
Model: WC-CS
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 MODEL: WC-CS
operation of down-hole tools used in drilling the well. The PROD. NO. WC-20701
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:- Magnet Inserts - The WC-RCB can be easily converted to a
fishing magnet by removing the catcher assembly and
Model: WC-RCB replacing it with a magnet insert. The insert still allows
Product No. WC-20702 direct or reverse circulation and can be used with A, B or C
The Wellcare Reverse Circulating Junk Basket type shoes, or special shoes designed to customer
(WC-RCB) is a junk retrieval tool designed to remove all specifications. The magnet insert is the same design as the
types of objects from the bottom of the well bore. This Wellcare Fishing Magnet and by adding a top sub to the
superior tool removes such items as slips, hand tools, bit magnet insert; it can be used independently as a fishing
cones, and any other small pieces of junk from the well. The magnet.
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.

85

Core-Type Junk Basket:-
Model: WC-CJB
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.

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.

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.

86

Impression Block
Model: WC-IB
The Wellcare Impression Block is an accessory
tool used to accurately determine the dimensions and
configuration of the upper end of a fish as well as to
check its condition and position in the well bore. The soft
lead lower end of the impression block captures an
impression of the fish upon making contact. Impression
blocks are manufactured with a pin connection up and a MODEL: WC-IB
layer of soft lead on the lower end of the tool. Circulation PROD. NO. WC-20704
holes will be provided on request.

Make up the impression block to the bottom of the
fishing string. Run into hole until impression block is near top
of fish. Slowly lower pipe until making contact with fish. Do
not rotate. Apply weight to impression block and then pull out
of hole. The impression made will assist the operator in
determining what tools are needed to prepare and retrieve the
fish.

87

Boot Basket (Junk Sub):-
Model: WC-BB
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.

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.

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.

engagement. A knurled release ring between the box and pin
sections maintain torsion integrity until back off procedure
is initiated. An O-ring seal contains pressure while the safety
joint is made up.
Assembly – To assemble, install the safety joint in
the drill string and make up the service connection to a
torque of approximately 60 to 75% of the string connections.
In washover strings, the safety joint should be
located between the drill pipe and the washover pipe.
Wellcare Washover Safety Joints are provided with a tool
joint box thread up and a washover pipe pin thread down.
To disengage the safety joint while down-hole,
place pipe in tension and apply left-hand torque. Hold torque
while slowly lowering pipe until safety joint breaks.
Continue to unscrew safety joint to the left. To re-engage the
safety joint, lower pipe until pin section of safety joint lands
on box section. Apply one point of weight. Rotate to the left

DOWNHOLE FLOW REGULATORS
Model: WC-DFJ & WC-DFL

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.

PROBES
Model: WC-PB , WC-PA & WC-PAC
Product No. WC-23901 , WC-23902 &
WC-23903
The Model WC-PA and WC-PAC Probes are used to
close the up-facing locks on any flow control accessory
having an S type lock. The Model WC-PA Probe,
equipped to carry a prong on the lower end, is used
when a prong is required and the Model WC-PAC , not
equipped for a prong,
should be used in all areas where a prong is not
required. As the probe enters the fishing
neck the blade automatically swivels past the down-
facing locks and retracts the up-facing
locks before the pulling tool latches on. The flange
shoulders against the fishing neck of
the accessory when setting or jarring down.
The Model WC-PB Probe is used to close the locks on
any flow control accessory having a W
or Z (top or bottom No-Go) type lock. The Model WC-

RUNNING TOOL
Model: WC-RGTL
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 MODEL:WC-RGTL
itself. This includes all running of flow control devices PROD. NO. WC-24001
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.
