Arrowset II

The Arrowset II is a double grip packer, which meets a variety of treating and production requirements. Mechanically operated upper slips eliminate the need for a hydraulic hold-down assembly. Full opening design allows unrestricted fluid flow and tool movement through tubing. A pressure balanced by-pass valve, which is held open when running and retrieving, prevents swabbing effect. The valve also allows debris to be washed from the top slips when releasing. The by-pass valve is held closed by pressure from below and in turn helps prevent upward movement of tubing.

The Arrowset II also features a patented upper slip releasing system that reduces the strain required to release the slips by dislocating a key non-directional slip first, which automatically releases the other slips.

The Arrowset II is available for right or left-hand operation, and with an automatic or manual jay.

Effectively meets several requirements for zone isolation, injection, pumping and production. Full opening gives unrestricted flow and allows the passage of wireline tools and other accessories.

• Operation simplicity, 1/4 turn right to set and straight pull release
• Slip design to distribute even load force over casing I. D.
• Patented slip releasing system
• Open "J" System to eliminate debris build-up
• By-pass location allows debris to be cleaned from upper slips
• Compensating piston holds by-pass valve closed
• Economical mechanical hold down eliminating hydraulic buttons
• Available in H2S trim or specialized material
• Available with specialized elements and seals

Setting -Run the tool to setting depth, pick-up tubing and rotate to the right 1/4 turn at the packer. Tubing weight is applied, which sets the lower slips, closes the by-pass valve, and expands the packing elements. The upper slips automatically set in the same operation.
Releasing -Raise the tubing, which first opens the balanced by-pass valve, then releases the slips and packing elements. The tool can now be moved and reset, or pulled from the well.
