CJ-A MECHANICAL SET Retrievable Service Packer

CJ-A Retrievable Service Packer — Full Opening, Compression Set

The Model CJ-A Retrievable Service Packer is a full-opening, compression-set packer suitable for a wide variety of well treatment and production installations. When run with the Model CSV Storm Valve, it also functions as a storm packer to provide well control protection during temporary well abandonment, without the need to retrieve the bottom-hole assembly. A wide range of sizes is available for use in 4 1/2″–16″ casing.

Model CJ-A packers feature a large internal bypass through the packer. The bypass allows for the free flow of fluids through the packer during running, retrieving, and circulation, which significantly reduces the swabbing effect on the packing element and wear on the Hold Down Pistons. These packers are used when high differential pressure from below the packer is anticipated and utilize hydraulically actuated Hold Down Pistons to anchor the packer against upward movement. This same hydraulic pressure acts on a balance piston located just below the closed face seal. The piston moves downward and shoulders on the body, thereby applying a downward force to the body and face seal. This action eliminates the need for excessive tubing set-down weight to keep the bypass closed.

FEATURES

• Carbide-inserted slips, pistons, and drag blocks set securely in any hardness of casing, including premium grades
• Three-piece packing element system with metal backups accommodates low- and high-pressure applications for the broadest range of service
• Hydraulic Hold Down Piston unit with a large internal flow path, located below the bypass valve to reduce element swabbing and button wicker dulling — activated by pressure from below
• Surface-controlled combination bypass and equalizing valve
• Tubing pressure-actuated hydraulic piston eliminates the need for excessive set-down weight — far more efficient than collet-type locking systems
• Automatic Jay Unit: setting is accomplished by running to depth, picking up a few feet, rotating 2–3 turns to the right, and setting down
• A straight pickup will first open the bypass valve and equalize pressure; continued pickup will release the packer and automatically return it to the running position
• Left-hand or Manual Jay Units are also available
• All pressure-bearing O-rings have backups for higher pressure resistance
• P110 body, coupling, and sub for high-load applications
• API EUE connections as standard
