1.0 DescriptionThe setting tool is deployed on tubing or coil tubing therefore can be used in high angle or a deviated well application, where wireline deployment may be difficult. The setting tool is pressure balanced throughout its operation. When the tool is fully stroked open, circulation is re-established through the tool.
2.0 Benefits/Capabilities• The Hydraulic Setting Tool does not require explosives or special equipment to function, which is a
benefit when operating in remote or difficult areas.
• The Hydraulic Setting Tool has 21 inches of working stroke, longer than standard setting tools.
• The tool pulls 120,000 lbs. with 3,600 (psi) applied pressure.
• Piston area for the tool with four working pistons is 33.3 in2.
• If required, additional pistons and companion cylinders can be added to the tool to reduce surface pressure requirements.
3.0 OperationWhen at setting depth a ball is dropped down the tubing and seals against the ball seat in the HST. Applied pressure will shear the ball seat and close the circulation ports. The applied pressure is now directed past the ball and towards the working pistons. Increase tubing pressure to the required amount to set and shear off from the tool being deployed with the HST. The HST will stroke fully open, the tubing pressure will drop and circulation will be re-established with the annulus.

9.0 Pre-Assembly
Warning: Make sure all tool parts and components have been thoroughly cleaned or serious damage and/or injury could occur!
Warning: Personal Protective Equipment (PPE) should be worn at all times!
Caution: Make sure to wrench only on wrenching surfaces (knurled areas) provided! Always file wrench marks and burrs and clean off debris!
Note: Verify that the correct O-ring redress kit and quantities are used as specified on the Bill of Materials (for example, 5 each etc.). Lay out all redress kit components on a clean surface.
Note: This tool takes at least two people to assemble and disassemble. Also, you need at least one each of the following to work on this tool: vise and work stand. Four roller stands are required to support the tool.
Note: Make sure to lubricate all O-rings and threaded surfaces.
Note: It is strongly recommended that MEMAC wrenches be used for assembly. These wrenches will not leave wrench marks when used on the knurled areas.
9.1 Place each O-ring in the appropriate groove as shown in the tool schematics in (Figures 1-3).
9.2 Place the top sub, (item #10) in a vice.
9.3 Attach the top sub to the snorkel tube, (item #8).

10.3 Insert the stroke compensation piston, (item # 9) into the stroke compensation housing. Attach the stroke compensation piston, (item #9) to the working piston, (item #14). Fully engage the piston threads. Adjust the roller stand to prevent thread binding.
10.3.1 This piston assembly utilizes a 1-1/4 American MT tapered thread that required a recommended makeup torque of 660 ft.-lbs. Equivalent load would be a 36 inch pipe wrench with 200 lbf applied.
10.3.2 To assist in assembly use the provided piston assembly tools
• Attach the installation sleeve to the compensation housing (item B).
• Slide the installation nut into the installation sleeve and line the hex nut into the compensation piston, (item A).
• Align the installation torque sleeve (item C) over the top of the piston assembly and now you can supply the required torque to the piston assembly. (See Figure 18)
