ED-JS Retrievable Packer

« Products (Overview) | « Packer Service ED-JS Retrievable Packer

ED-JS Retrievable Casing Packers are full opening, set-down type hook wall packers that are applicable for a wide variety of well treating and producing installations. Can be used as a Storm Packer in combination with ED-Stormvalve ( Maximum Load 7” ... 200,000#; 9 5/8”... 350,000#). The packers are available in 7" & 9 5/8" OD casing and feature a large internal bypass through the packer which communicates with a surface controlled set-down face seal type valve. The bypass provides free flow of fluids through the packer during running, retrieving, and circulation, thus greatly
reducing packing element swabbing and button slip wicker dulling. These packers are used when high differential pressure from below the packer is anticipated and utilizes hydraulically actuated button type slips to anchor the packer against upward movement. This same hydraulic pressure also acts on a balance piston, which is located just below the closed face seal. The piston moves downward and shoulders on body thus placing a downward pull on the body and face seal. This action eliminates excessive tubing set-down weight required to keep the bypass closed.

Features
• Sets securely in any hardness casing, including premium grades.
• Three piece packing element system with metal backups accommodate
low and high pressure applications for the broadest range of service.
• Hydraulic hold down button unit with large internal flow path located
below the bypass valve to reduce element swabbing and button wicker
dulling. These hold down piston type slips are set by pressure from below.
• Surface controlled combination bypass and equalizing valve.
• Tubing pressure actuated hydraulic piston eliminate excessive set down
weight requirements. This feature is far more efficient than collet type
locking systems.
• Automatic Jay Unit, setting the packer is accomplished by running to
depth, picking up a few feet rotating 2/3 turns to the right and setting down.
• Straight pickup of the tubing will first open the bypass valve and equalize
pressure, continued pickup will release the packer and automatically
engage the packer in the running position for further operations up
or down the hole.
• Wicker slips are machined from 4140 promising the ultimate sharpness
and hardness. Lower slips are held fully retracted during running and
retrieving. Slips and pistons are also available with carbide inserts.
• Friction pads are also available with carbide inserts.
• All Thread connection come standard in API IF thread form.
• All Pressure bearing o-rings have backups for higher pressure resistance.
• Load and pressure resistance designed to meet high load applications.
• Field-proven design, recommended to 300°F applications, if need high Temp.
