Packer, SA-3™ LOK-SET® Retrievable, 7" 20.0-26 lb/ft
The SA-3™ lock-set retrievable casing packer is a general purpose packer for production, injection, zonal isolation, or remedial operations, it holds pressure from above and below, while allowing the tubing to be placed in tension, compression, or in a neutral condition. The SA-3 lock-set retrievable casing packer incorporates a three-piece element system. The element system is bonded on to a one-piece system for increased swab-off resistance. The SA-3 lock-set retrievable casing packer is a fullbore double-grip retrievable packer with an integral unloader, opposing, 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 that maintains 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 tool to be both set and released with right-hand rotation.
Since the retrievable SA-3 packer is not affected by forces transmitted by the tubing, it may be used in many applications where a mechanical set retainer production packer might be used. The SA-3 packer may also be used with the parallel string anchor, above a retainer production packer, or any other hook-up which allows right-hand tubing rotation, with upstrain, to release the lock-set packer.
