Liner Hangers

HCHR

High-capacity hydraulic rotating liner hanger

Deploy heavy and long liners in drilldown applications, even in deep land, deepwater, and HPHT wells, to save time and enable rotation.

HPS

Configurable hydraulic pocket-slip liner hanger

Run long and heavy liners with confidence, even in HPHT conditions, with or without liner rotation during running or cementing.

SBRD

Solid-body mechanical-set liner hanger

Run light and medium-weight liners in wells where the workstring can be manipulated to set the hanger.

Liner Top Packers

PV-3

Liner top packer with or without hold-down slips

Choose a reliable packer rated to 10,000-psi [68.9-MPa] differential pressure.

PV-0

High-pressure V0 liner top packer

Run this V0- or V3-qualified packer above the COLOSSUS CMT liner hanger system in HPHT wells to enable drilldown and rotation.

Running Tools

CRT

Hydraulic collet running tool

Run liners and release without rotation—ideal in high-inclination wells.

RRT

Right-hand-release running tool

Mechanically or hydraulically set liner hanger systems that require high torque to drill the liner.

RCB

Retrievable cement bushing

Maintain pressure integrity for liner hanger and liner top packer operations.

RBS Rotational Ball Seat

Simplified running and setting

Save time running and setting liner hanger systems, and reduce pressure surges.

Cement Heads

CMIB Light

Internal-bypass cement manifold

Control cementing of liner hangers, including rotating systems, on small land rigs.

CMIB

Internal-bypass cement manifold

Control the flow of cement and displacement fluids during liner cementing operations.
