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.
Applications:
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.

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

SETTING
PROCEDURE
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
PROCEDURE
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. |
