Grip Type Double Grip
Machine Type Mechanical Packer
Condition New

This 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.

Benefits :

Differential lock helps keep the by-pass closed and locked to the
mandrel during high pressure operations.
Automatically returns to run-in position when moved up the hole.
Hydraulic hold-down buttons for differential pressure from below.
Long stroke mandrel simplifies circulation of fluids without releasing
the packer.
Large by-pass allows speedy equalization of fluids.
Rocker type slips.
Standard right-hand set, optional left-hand set.
Parts are interchangeable with other manufacturers.

Setting procedure : The Double Grip Packer runs in with the by-pass valve in the open position to permit free circulation both through and around the packer. The packer should be run one foot below the setting depth. To set, pick-up the tubing to the desired setting position, rotate to the right and then slack-off. The J-pin will move clear of the J slot and the cone will move under the slips. Application of set-down weight, for standard packing element system (7, 000 lb for sizes 4-1/2 5-1/2, 5, 000 lb for sizes 2-7/84-1/2, 9, 000 lb for size 7", 11, 000 lb for size 8-5/8 and 15, 000 lb for size 9-5/8), closes and seals the by-pass valve, sets the slips and packs-off the packing elements. The formation below the packer, which is now completely isolated from the annulus above, is accessible only through the tubing string.

Releasing procedure : To release the packer, raise the tubing string, as the J-pin of the bottom sub engages the slip stop ring (jay housing), the J-pin automatically moves into the running position. This allows the tool to be moved up or down the wellbore as necessary. When the tubing is raised to release the packer, the by-pass valve opens to permit circulation through and around the packer.

Note : If the J-Pin whould un-jay when the tubing is slacked off, rotates to the left (only enough to remove any right-hand torque form the tool) and pick up.
