JS-3 removable storm packer can be widely used in oil production, stimulation measures, perforating, gravel packing and well testing operations. The hydraulic anchor is located below the pressure balancing valve. The packer is designed with a sealing system composed of three rubber barrels, and is designed with a hydraulic control balance valve to ensure that the bypass balance channel of the packer is closed during setting.
The JS-3 packer is suitable for casing from 5” to 20” outside diameter.
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.
