LOCK SET
PACKER

The Lock Set Packer is a general purpose casing packer for production, injection, zone isolation, or remedial operations. The Lock Set Packer holds pressure from above or below while allowing the tubing to be placed in tension, compression, or in a neutral condition.

DESCRIPTION
The Lock Set Packer is a "full bore" retrievable casing packer with a built-in unloader. Opposed, non-transferring dovetail slips and a releasable packer mandrel lock system prevent packer and tubing movement due to pressure differentials. The mandrel lock system maintains pack-off and locks the unloader in the closed position until the packer is released. Tubing can be landed in tension, compression or neutral. Right hand rotation sets and releases this packer.

USE
The Lock Set Packer is not affected by forces transmitted by the tubing and may be used in many applications where a permanent production packer might be used, such as
•  A lower packer for dual packer completions with an upper dual packer that is set by short string weight
•  With snap set tension packers
•  With snap set compression packers
• With parallel string anchors
• Above a permanent packer
• Any other hook-up which allows right hand rotation, with upstrain, to release the Lock Set Packer.
