PV-0

High-pressure V0 liner top packer

Optimize well integrity and enhance well stability and safety

Designed to suit most oil and gas applications, including hostile gas environments, the PV-0 high-pressure V0 liner top packer is a component of the cemented liner hanger system.

Meeting ISO 14310 liner top packoff requirements with qualified HNBR and AFLAS elements, the packer enables drilldown and rotation of the liner.

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.
