TECHNICAL UNIT
BRICO OIL TOOLS provides a dependable line of Wireline Pressure Setting Tools for the
Wireline industry worldwide. Our engineering, high quality and service provides a cost effective
Alternative.
BT #20 Introduction
The BT #20 Setting Tool Assembly is devised for setting of equipment in the well bore on electric
Wireline. Products of combustion are utilized for the gradual development of force through pressure
thus hydraulic force is transferred through the tool, through the Wireline Adapter Kit to a packer,
bridge plugs, cement retainers, frac plugs to fully set the slips and pack off the sealing element of
these products. This motive force operates the various working parts of the BT# 20 setting tool in a
proper sequence to ensure a force in excess of 60,000 lbs. / 26.6 daN. The tool may be used in
multiple tasks on highly deviated well bores via a well bore tractor, e-coil and can incorporate a
casing collar for depth correlation. A wide range of firing head adapters and Wireline accessories
are available from BRICO Oil Tools.
The high pressure required within the tool is built up through the burning of a Slow Set Power
Charge, or a Standard Power Charge. For specifics on all Power Charges and Igniters refer to
BRICO Tech info on Power Charges and Igniters Manuals. The setting pressure is confined to the
proper area of the setting tool through the use of o-ring seals or chevron seals on the high
temperature tool. It is of extreme importance that all of these o-rings and seals be maintained in
perfect condition and all tool internals are completely cleaned prior to assembly.
The standard BT #20 Setting Tool Assembly incorporates a Disk Bleeder Valve to provide a safe,
easy method of bleeding off trapped pressure from inside the tool after it has been run and before
being back loaded for transport. The tool should be bled off once the tool has been pulled from the
well bore. This tool should never be transported without the tool pressure released or bled off.

Operating Instructions
To ensure safe operation of the size BT#20 Standard Wireline Pressure Setting Assembly, do not run if the
hydrostatic pressure will exceed 15,000 psi. When hydrostatic pressures at setting depth are greater than
15,000 psi, the standard size Upper and Lower Cylinders must be replaced with special heavy duty Cylinders.
Replace the Standard Pressure Assembly Chamber, Upper and Lower Cylinders with heavy duty Pressure
Chamber and Cylinders. Contact BRICO Oil Tools for a High Pressure BT#20 model.

NOTE: It is imperative that the specification guides for the various tools set with the #20 Setting Tool
be followed strictly in regard to the size used to set the various sizes of the tools and setting forces.
General Assembly Information
All O-rings must be replaced after each run. All O-rings should be lightly lubricated with downhole grease or
motor oil. Do not get excess grease or oil inside the tool. Under no circumstances should any other o-rings
be used than those specified in the Parts Lists.
All threaded connections should be lubricated with thread dope and then made up tight.
If the tool is to be stored prior to its use, oil should not be put in the Cylinder until it is taken out of storage to be
run.
Oil Levels are Critical


Not enough oil shortens the setting stroke, resulting in failure to part the release stud.
Too much oil will result in presetting or a fast set.

after long term storage.
Note: See Oil Level Filling Information on page 3
Size BT # 20 Setting Tool - Filling Oil, Installing Charges and Tools
1. Remove the Upper Cylinder (7) from the Cylinder Connector (8). Stand the upper section of the setting
tool on a clean surface with the Cylinder facing upward. Use a clean wooden dowel or broom handle to
check that the Floating Piston (6) is completely bottomed out against the Bleeder Pressure Chamber (5).
2. Fill the Upper Cylinder (7) with clean oil to the proper level for the temperature at your setting depth as
shown in Chart above using the Dip Stick or ruler to measure depth of Oil in the Upper Cylinder (7). Pick
up the lower section of the WLPSA and make it back up into the Upper Cylinder (7) and tighten the
connection.
3. Check the Bleeder Valve for proper installation and tightness. Use the Bleeder Wrench (2) to check that the
Bleed Nut (3) is tight (this is a left-hand thread).
Refer to manufacture of Power Charges and Igniters for the proper selection of Power Charges
and Igniters
4. Take the Firing Head and remove the Cartridge Seat from the Head. Notice that this is a left-hand
thread. Install a Secondary Igniter into the bottom end of the Cartridge Seat and use the Truarc Ring
provided to retain the Secondary. Notice that no groove is provided for the Truarc Ring to snap into. The
ring is held in place by friction alone and is blown out when the Igniter fires.
5. Install an Igniter into the top of the Cartridge Seat and retain with the Cartridge Seat Cap. Be sure that
the O-ring is in place between the Igniter and the Cartridge Seat and that the Cartridge Seat Cap is
tightened enough to provide a good ground for the Igniter.
6. Use an Ohmmeter to check the Firing Head for electrical continuity (should read near 0 ohms
resistance) from the Connector to the Firing Pin. Check for shorting (should read infinite ohms) from
the firing Pin to the Head.
7. Make up the Wireline Adapter Kit and the product to be set to the #20 Setting Tool. Refer to the Tech
Unit of the specific product being set for assembly instructions.

8. Remove the plastic cap from a Power Charge and place the Power Charge into the Pressure Chamber
with the open end of the Power Charge facing the open end of the Pressure Chamber.
9. Remove the Firing Head from the Collar Locator or Cable Head. Install and tighten the Cartridge Seat
into the Head. Then install and tighten the Firing Head into the Pressure Chamber.
10. Use a safety meter to check the resistance from the Firing Head Connector to the Head. This checks the
resistance of the Igniter which should be 2.5-5 ohms for a BP-3S Igniter and confirms that the Firing
Head and Igniter are installed correctly. (Other Igniters will read different and refer to Manufacturer’s
Manual for correct check and equipment to be used.) Make the Firing Head back up to the Collar
Locator Cable Head.
11. Pick up the tools, check zero and run in the hole at a speed no higher than 300 feet per minute, being
careful to slow down when approaching the fluid level. Continue running several feet past setting depth
if possible. Check odometer and weight indicator and pick up slowly to setting depth.
12. Fire Igniter: Depending on depth, well fluid and other conditions as many as three distinct impulses can
be felt manually on the electric line or observed on the weight indicator as the tools set and shear off.
13. Wait approximately one [1] minute after the last weight indicator flickers to be sure that the tool is set.
Then, if possible, slack off a few feet and watch the weight indicator for a drop to indicate that the tool
has set. With some tools, slacking off will re-engage the Wireline Adapter Kit and could cause you to
hang up and not be able to pull free. Pick up slowly and note the setting depth by the weight increase,
remembering that the #20 Setting Tool has increased about one [1] foot in length due to stroking out.
14. Retrieve the tools at a rate no higher than 300 feet per minute. A much slower rate should be used if
there is any doubt about the tool being sheared off.
WARNING
After the Firing Head and #20 Setting have been run and fired, gas under very
high pressure will be trapped inside the tool.
THIS PRESSURE MUST BE BLED OFF BEFORE TRANSPORTING AND
DISASSEMBLY HAS BEGUN. FAILURE TO COMPLY WITH THE FOLLOWING
BLEEDING INSTRUCTIONS MAY RESULT IN SERIOUS INJURY. DO NOT
TRANSPORT THE TOOL UNTIL THE PRESSURE HAS BEEN BLED OFF.
PPE / Safety glasses, gloves and long sleeves must be worn while bleeding
pressure off of the Setting Tool. The Setting Tool should always be bled in a
well-ventilated area.
As soon as the Setting Tool is removed from the well, trapped pressure in the tool should be bled off through the
Bleeder Valve. Bleed in an open, well-ventilated area. Place the tool so that the Bleeder Valve faces up. Locate the
Bleeder Valve Vent Hole next to the Bleeder Valve. Make sure this vent hole is pointed away from all personnel.
Stand on the side of the tool away from the vent hole. Bleed as follows:
When using Disk Bleeder Valve, screw the Bleeder Wrench Piercing Screw in until the Piercing Disk is punctured.
Do not make a full circle with the wrench. Keep hands away from the vent hole at all times. When the tool starts to

bleed, make an additional half a turn and then stop. Do not screw the Piercing Screw in tight. It can seal against the
Piercing Disk and pre-vent bleeding. Do not turn the Piercing Screw to the right until the tool is completely bled off.
If the tool does not bleed off when the Piercing Screw is bottomed out, carefully turn it back 1/4 turn, watching to be
sure that the Bleed Nut does not turn. If the tool still will not bleed off, do not remove the Piercing Screw, use the
“Secondary Bleeding Procedure” described below.
15. Redress the Setting Tool before running again.
Secondary Bleeding Procedure
The Disk Bleeder Valve can be run in the Heavy Duty Setting Tool, but the Manual Bleeder Valve cannot. If you
do not have a Disk Bleeder Valve for the heavy duty tool, a Pressure Chamber less Bleeder Valve must be run.
The following bleeding procedure must then be used. This procedure can also be used on any tool if either
Bleeder Valve fails to bleed pressure off the tool.
Safety glasses, gloves and long sleeves must be worn while bleeding pressure off of the Setting Tool. The
Setting Tool should be bled in a well-ventilated area.
Before attempting the secondary bleed-off procedure, allow 6 to 8 hours for the tool to cool down, this cool down
period will reduce the high pressure within the tool.
Clean any debris from the bleed hole in the top end of the Upper Cylinder (7). Hold back up on pressure
chamber. Position bleeder hole in pressure chamber away from you and slowly unscrew firing head a maximum
of 1-1/4" from pressure chamber. If pressure does not bleed off position bleeder holes in upper cylinder away
from you and slowly unscrew pressure chamber until pressure escapes. Do not back off pressure chamber
more than 1-1/4” from cylinder at this point. If pressure still does not bleed off, back off firing head exactly 1-1/4”
from pressure chamber. If the tool cannot be bled off, contact the BRICO OIL TOOLS representative.

Running in Extreme Temperatures
When running in temperatures expected to be in excess of 350 degrees F, it is suggested that the Gage Ring,
Wireline Feeler and Junk Catcher be run on the Firing Head with an Igniter in place. After the run, check the
Firing Head for leaks and high temperature firing of the Igniter. If the Igniter has been fired by high well
temperatures, it will be impossible to run the Setting Tool to the setting depth without danger of premature
setting. If any fluid is found inside the Firing Head, all parts must be dried, sealing surfaces examined and all Orings inspected and replaced. It is very important that all new O-rings be used when the Setting Tool is run, as
fluid around the Pin would prevent the Firing Head from operating. Do not reuse the Igniter! Discard and use a
new Igniter.
It is a good idea to find the setting depth on the Gage Ring run and flag the Wireline at setting depth. Then run
in the hole as fast as possible for the tools being run and fire the setting tool as soon as the flag is reached and
the Wireline has quit oscillating. This will minimize the temperature that the Power Charge and Igniters will heat
up to before being fired.
Disassembly BT#20
WARNING
After the Firing Head and #20 Setting Tool have been run and fired, gas under
very high pressure will be trapped inside the tools.
THIS PRESSURE MUST BE BLED OFF BEFORE TRANSPORTING and
DISASSEMBLY HAS BEGUN. FAILURE TO COMPLY WITH THE FOLLOWING
BLEEDING INSTRUCTIONS MAY RESULT IN SERIOUS INJURY.
PPE / Safety glasses, gloves and long sleeves must be worn while bleeding
pressure off of the Setting Tool. The Setting Tool should always be bled in a
well-ventilated area.
1. Lay tools down, being careful not to damage Adapter kit. Place in a well-ventilated area and bleed as
follows:
a) Disk Bleeder Valve: Place the tool so that the Bleeder Valve faces up. Locate the Bleeder Valve Vent Hole
next to the Bleeder Valve. Make sure this vent hole is pointed away from all personnel. Stand on the side of the
tool away from the vent hole. Screw the threaded portion of the Bleeder Wrench (2) into the Bleed Nut until the
Piercing Disk is punctured. Do not make a full circle with the wrench, keep hands away from the vent hole at all
times. When the tool starts to bleed, make an additional half turn and then stop. Do not screw the threaded
portion of the Bleeder Wrench in tight. It can seal against the Piercing Disk and prevent bleeding. Do not turn
the Bleeder Wrench to the right until the tool is completely bled off. If the tool does not bleed off when the
threaded portion of the Bleeder Wrench is bottomed out, carefully turn it back 1/4 turn, watching to be sure that
the Disk Retainer does not turn. If the tool still will not bleed off, do not remove the Piercing Screw, use the
“Secondary Bleeding Procedure”.
2. Unscrew Cable Head. Important: If the Cable Head is tight, indicating that pressure has leaked into it,
follow “Secondary Bleeding Procedure” under Operating Instructions. All Pressurized gas must be
exhausted before disassembly is begun.
