Gas Vent Pumping Packer offers an inexpensive option for isolating casing leaks or depleted perforations in pumping wells. This tools prevents gas lock by allowing gas to vent to the surface past damaged zones. The interval between top and bottom cups can be of required lengths. Available with double or multiple cups.

Benefits :

• Inexpensive alternative to squeeze job.
• Variable intervals easily adjusted.
• Optional double to multiple cups.

Swab Cup Packer is an economical means of isolating casing leaks and depleted zones. It is also a production or injection packer for low pressure application. This packer can be run with cups opposed or in the same direction with packing element back-up rings for higher pressure application and comes in a full range of tubing and casing sizes in two-cup or four-cup models.

Benefits :

• Economic design
• Cup direction option
• Tubing size options

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.

Benefits :

• Internal by-pass.
• Opposed dovetail slips positive set.
• Holds pressure from above or below.
• Can leave tubing in a tension, compression or neutral condition.
• Right hand rotation sets and releases the packer.
• Retracted dovetail slips.
• Converts to mechanical bridge plug with the addition of a valve.
• Optional packing element systems.
• Parts interchangeable with other manufacturers.

Applications :

• Production.
• Injection.
• Zone isolation operations.

Note: The Model: WC-MECH-3L Lok-Set Packer is similar to the Model: WC-MECH-3 packer and is recommended when a larger than normal bore through the packer is required.

MECH-10, Mechanical Set Production Packer is a high performance Full Bore Single String Retrievable packer. It is specifically designed to perform reliably in high pressure fracturing and production applications.It is compression set and can be landed in compression, tension, or a neutral condition. It is available reliable performance in a retrievable packer under combined conditions of 350F and 10, 000 psi differential above or below the packer.

Features/Benefits:

Ease of operation - 1/4 turn to right to set, 1/4 turn to right to release

High performance three-piece element system for high pressure sealing and pressure reversal loads

Independent lower and upper Jay Assemblies contributing to short, compact design

Tubing can be landed in tension, compression or neutral

Full opening ID for stimulation and thru-tubing perforating

Built in un-loader with bonded seal for bypass

Bypass opens before release of upper slips for safety and ease of release, Staged loading of upper lips for ease of release

Solid upper slip cone for added strength and elimination of release sleeve, Reliable and rugged rocker type lower slip assembly

Technical Specifications mentioned below:

MTP, thermal packer is designed for steam injection/production wells. It is a double grip tool, which utilizes the upper slip releasing system. The WC-MTP simple 1/4 turn, right-hand rotation to operate eliminates the need for tedious torque which may damage the tubing. After rotating 1/4 turn to the right, the WC-MTP is set with tension. It used for steam injection/production wells. An internal by-pass reduces the swabbing effect during run-in and retrieving. The by-pass closes upon setting the packer. During releasing, the by-pass opens allowing the pressure to equalize.

Features/Benefits:

Holds pressure differential from above and below

Only 1/4 turn rotation required for operation

Choice of packing systems

Field proven releasing system

Variable shear safety release

An internal by-pass reduces the swabbing effect during running and retrieving.

One piece mandrel through packer.

Packer is a full-opening, hook wall packer used for testing, treating, and squeeze cementing operations. In most cases, the tool runs with a circulating valve assembly. Packer body includes a J-slot mechanism, mechanical slips, packer elements and hydraulic slips. Large, heavy-duty slips in the hydraulic hold down mechanism help prevent the tool from being pumped up the hole. Drag blocks operate the J-slot mechanism on packer bodies. Automatic J-slot sleeves are standard equipment on all packer bodies. Circulating valve, if used, is a locked-open/locked-closed type that serves as both a circulating valve and bypass. Valve automatically locks in the closed position when the packer sets. During testing or squeezing operations, the lock prevents the valve from being pumped open. A straight J-slot in the locked-open position matches with a straight J-slot (optional) in the packer body. This combination eliminates the need to turn the tubing to close the circulating valve or reset the packer after the tubing has been displaced with cement.

Features and Benefits:

The full-opening design of the packer mandrel bore allows large volumes of fluid to pump through the tool. Tubing-type guns and other wire-line tools can be run through the packer.

The packer can be set and relocated as many times as necessary with simple tubing manipulation.

Bi-directional carburized slips provide greater holding ability and improved wear resistance in high-strength casing.

Pressure through the tubing activates the slips in the hydraulic hold down mechanism.

An optional integral circulating valve locks into open or closed position during squeezing or treating operations and opens easily to allow circulation above the 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.
