Mechanical Single/Double Grip Retrievable Packer

mechanical single/double grip retrievable packer is a retrievable set-down packer that features a large bypass area. The bypass area is controlled by a face-seal type bypass valve which is 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 buttons) for combination production and well stimulation operations.the double-grip packer are used where pressure differential from below the packer is anticipated, features an integral hydraulic hold-down buttons that is located below the bypass valve. The double-grip packer also incorporates a unique built-in “differential lock” that 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 to maintain the force necessary to keep the bypass valve closed. This is a single grip, compression set and retrievable packer.
