Description
This compact hydraulically set retrievable production packer is designed for zonal isolation and creating an annular pressure barrier. The packer is made up of the tubing string and runs in the hole to the set depth. An anti reset function prevents the packer from accidentally setting while running in the hole.
The packer is set by applying hydraulic pressure against a plugging device in the tubing string below the packer. During setting, the slips and seal elements are forced against the casing wall, anchoring the packer in place and creating a pressure-tight seal. Multiple retrieval methods are offered, however once the packer has been released a direct pull on the tubing string allows the seal elements to decompress and the slips to retract. The anti-preset mechanism has an additional function where it locks the packer in the release position, thus preventing it from resetting while pulling out of the hole. This allows the packer to be pushed/pulled without the danger of slips resetting.
Application
- The unique design offers a full differential working pressure rating.
- Retrievable production annulus pressure barrier.
- Ties the production tubing to the production casing for zonal isolation.
- Optional Release features – Pull, Cut, Control Line, Shift Sleeve.
- Sizes to suit 4-1/2” to 13-3/8” casing.
- Materials to suit all well environments.
- Available in multiple configurations.
Benefits
- Allows multiple control lines to bypass packer.
- Compact design.
- Single piece mandrel with no leak paths.
- No movement between tubing/casing during setting.
- All shear pin stubs are retained after shearing (no debris left downhole).
