Mechanical Packer

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...

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 2-7/8~4-1/2, 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.

This is a mechanical set double grip retrievable production packer for medium to high Pressure applications. The Packer allows unrestricted flow and passage of full gauge wire line tools and accessories with an unrestricted ID, making it ideal for zone isolation injection and production applications. It can be set with production tubing in tension, compression or neutral maximizing effectiveness in shallow wells or fiberglass tubing operation. The packer’s mechanical lock-set action closes an internal bypass and allows application of pressure above or below the packer. The packer is released by a ¼ right-hand turn at the tool, followed by straight pickup of the production tubing. Optional emergency release feature is also available on request.

Benefits :

• Pressure differential rating up to 6,000 Psi.

Benefits :

• Pressure differential rating up to 6,000 Psi.
• 10,000 Psi., Differential rating packer is also available.
• Allows tubing to be left in tension, compression or neutral.
• Internal By-Pass allows packer to equalize prior to releasing.
• Temperature rating : Up to 300° F.
• An ideal production packer.
• Withstands pressure differentials from above and below.
• Ideal packer for Production, Stimulation & Injection purposes.
• Tubing can be recovered leaving packer downhole by using an On-
• Off tool.

Applications :

• Onshore-Offshore work over.
• Production completion.
• High Pressure Water Injection.
• Casing integrity Testing & treating operations

This is a single grip, compression set and retrievable packer.

Benefits :

• Automatically returns to run-in position when moved up the hole.
• Long stroke mandrel simplifies circulation of fluids without releasing
• the packer.
• Large by-pass area allows speedy equalization of fluids.
• Rocker type slips.
• Standard right-hand set, optional left-hand set.
• Parts interchangeable with other manufacturers.

Applications :

• Low pressure production.
• Stimulation.
• And testing operations.

It is a general purpose packer for production, injection, zone isolation or remedial operations. It holds pressure from above or below while allowing the tubing to be placed in tension, compression or in a neutral condition. This is a Full-Bore Double-Grip Retrievable Packer with an integral un-loader. Opposed non-transferring dovetail Slips prevent movement of the Packer in either direction due to pressure differentials, while allowing landing of the tubing in tension, compression or neutral. The Lock segments serve as a releasable Lock Ring to maintain pack-off once the packer is set, and locks the un-loader in the closed position until the tool is released. The split Lock and Control Segments allow the tool to be set and released with right-hand rotation. The Retrievable Lok-Set Packers are compression set retrievable packers.
