Cement Retainer

The JAS CR is designed to function as a drillable squeeze packer that acts as a plug after cementing, which in turn traps squeeze pressure on the cement below the retainer and isolates the newly cemented area from the hydrostatic pressures above the cement retainer.

The JAS CR Snap-Latch Setting Tool is designed to reliably set a mechanical cement retainer using tubing or drill pipe string. The JAS CR mechanical setting tool is designed to run and set CR sleeve valve cement retainer.

FEATURES

• Can be set mechanically by tubing or drill pipe.
• Run-in speed is determined by the operator.
• Work string can be tested before squeezing by picking-up to close the valve.
• Automatic valve closing when picking-up the work string
• Effectively isolates squeeze from hydrostatic pressure.
• New material specifications developed result in faster drill out.
