High-pressure V0 liner top packer
Improve efficiency of circulation and hole cleaning, and minimize trip time
Its large fluid bypass area also enables 15 bbl/min circulation rates, improving hole cleaning and reducing circulation and trip time. The packer is run above the liner hanger system with either a mechanical right-hand-release running tool or hydraulic collet-running tool in HPHT environments.
The packer's high torque capacity also means you can rotate even long liners. Optional hold-down slips ensure even weight distribution around the supporting casing ID to accommodate high-capacity requirements.
