A-2 Lock Set Packer

The Evolution A-2 Lock-Set Retrievable Casing Packer is a full bore double-grip retrievable packer with an integral unloader.

Opposed, non-transferring dovetail slips prevent movement of the packer in either direction due to pressure differentials, while allowing landing of the tubing in tension, compression or neutral.

The Evolution A-2 Lock-Set Retrievable Casing Packer is a full bore double-grip retrievable packer with an integral unloader.

Opposed, non-transferring dovetail slips prevent movement of the packer in either direction due to pressure differentials, while allowing landing of the tubing in tension, compression or neutral.

The lock segments serve as a releasable lock ring to maintain pack-off once the packer is set and locks the unloader in the closed position until the tool is released. The split lock and control segments allow the tools to be both set and released with right-hand rotation.

The Packer holds pressure from above or below while allowing the tubing to be landed in tension, compression or in a neutral condition. The setting and releasing are controlled by right-hand tubing rotation.

Running Procedure

Hang the Packer to completely stretch it out before starting in the hole. Immediately prior to running in, rotate the Drag Block Housing several turns to the left to make sure the Segments are functioning properly. Do not rotate the Drag Block Housing to the right as this will bind the Control Segments and prevent them from moving after reaching setting depth. Upon reaching setting depth, slowly lower the packer while applying approximately two turns of right-hand rotation at the tool, until the tool takes weight. Set down a minimum of 6,000 lbs to initially set the Upper Slips. Lowering of the tool must take place while rotating for the tool to set properly. To fully engage the Lower Slips, apply an up-strain against the tool. When the tubing is to be landed in tension, a strain greater than the landing strain should be applied during the setting operation. The tubing may now be hung in tension, compression or neutral.
