OptiPkr Production Packer - (en)
Combines the robust performance of a permanent packer with the flexibility of a retrievable packer in one tool for demanding wellbore conditions
Applications
- Conventional, monobore, and stacked completions
- Liner-top isolations
- Subsea environments
- Extended-reach, deviated, and high-pressure, high-temperature wells
Features and Benefits
- The slip-element-slip configuration enables the packer to withstand pressures up to 10,000 psi (69 MPa) and temperatures up to 350°F (177°C), and to achieve a reliable seal by locking the element in place under variable loads and pressure cycling.
- The simple three-piece element design enhances tool reliability by incorporating a patented fold-backup system to provide extrusion protection.
- The mechanical interlock is actuated before the packer is set. This mechanism reduces the risk of premature setting or pin shearing if the packer encounters obstructions as it runs downhole.
- The option to set the packer hydraulically or hydrostatically, or to actuate the packer electronically with a radio-frequency-identification (RFID) trigger, enhances tool versatility.
- The large inside diameter (ID) of the packer accommodates monobore completions.
- The packer eliminates mandrel movement while setting, which enables stacked completions.
- The patent-pending slip design offers near-360° casing contact, which reduces slip-to-casing stress and minimizes internal casing damage.
- The upper slips are set up in sequence to minimize overpull and to simplify removal.
- Cut-to-release technology enables easy removal even after the packer has been placed under extreme loads.
- An anti-reset mechanism prevents the slips or element from resetting during retrieval.
- Rotationally locked features reduce mill-up time, if milling is necessary.
Tool Description
The Weatherford OptiPkr™ production packer combines the robust performance of a permanent packer with the flexibility of a retrievable packer into one tool. It provides a reliable seal between the outside of the production tubing and the inside of the casing in demanding wellbore conditions. The packer has a modular design that adapts to most applications and wellbore conditions, and enables conversion between hydraulic-, hydrostatic-, and RFID-setting modes. It exceeds ISO 14310 Level V0 standards for load and pressure.
