This packer is a retrievable set down packer that features a large by pass area through packer. The bypass area is controlled by a face seal type bypass valve which actuated by a 30 inch stroke mandrel.

The packer is available in a single grip version for use as a conventional long-stroke production packer and in a double-grip version (with hold down) for combination production as well as stimulation operation.

The double–grip packer for use where pressure differential from below the packer is anticipated features an integral hydraulic button-type hold down that is located below the bypass valve.

The double-grip packer also incorporates a unique built-in “Differential Lock” which utilizes a balance sleeve actuated by pressure from below the packer. This pressure creates an additional downward force which combined with set-down weight helps maintain the force necessary to keep the bypass valve closed.
A size 45 X 2-3/8 packer (see specification guide) is available for running in 5 ½” casing only with full-opening for running for 2-7/8” tubing.
