SR-3 Double-Grip Retrievable Packer

The SR-3 Double-Grip Retrievable Packer is a truly versatile setdown-type packer. Proven by its worldwide use, it performs reliably in production, stimulation, and testing operations.

To Set the Packer The SR-3 Double-Grip Retrievable Packer is set by picking up, rotating to the right and then slack- ing off on the tubing. Setdown weight closes the seal on the bypass, sets the slips and packs off the packing elements. 

To Release Packer Picking up the tubing releases the packer (no rotation required). When the tubing is raised, the bypass valve opens to permit circulation through and around the packer. When the tubing string is raised the full length of the packer, the J-pins (on the bottom sub) are oriented for automatic reengagement. By then lowering the tubing slightly, the J-pin engages the J-slot thus assuring complete release and preventing accidental resetting while retrieving the packer.
