Wellcare - Model WC-MECH -Double Grip & Large Bore Retrievable Packer
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 W casing only with full-opening for running for 2-7/8" tubing.
