High-performance liner hanger systems
Engineered for the most challenging well environments
The collet running tool (CRT) is a hydraulically released running tool that requires no rotation to be released from the liner, thereby making it suitable for applications with high-inclination wells. The clutch and premium tool joint connections permit high-torque rotating and drilldown capabilities throughout the liner system. When a rotational liner hanger is deployed, the CRT also enables the liner to be rotated after the liner hanger is set.
The CRT also has a backup mechanical-release mechanism to ensure its release from the liner.
The CRT is used to run liner hanger systems that use the PV-0 high-pressure V0 liner top packer or the setting adapter, such as the cemented or uncemented liner hanger system. The setting string assembly comprises a CRT, a slick joint, a cementing packoff bushing, a liner wiper plug adapter, and an extension to connect to the running string. A packer dog assembly can also be included if an LTP or PV-0 packer is run.
The tool helps reduce the risk of premature liner release and enhances well stability and safety by adding backlash protection. It also minimizes completion time and improves zonal isolation by enabling liner rotation while running into the well and while cementing.
Choose a reliable packer rated to 10,000-psi [68.9-MPa] differential pressure.
Run this V0- or V3-qualified packer above the COLOSSUS CMT liner hanger system in HPHT wells to enable drilldown and rotation.
Run long and heavy liners with confidence, even in HPHT conditions, with or without liner rotation during running or cementing.
Deploy heavy and long liners in drilldown applications, even in deep land, deepwater, and HPHT wells, to save time and enable rotation.
Eliminating a dedicated liner run through a high-loss gassy salt zone reduced rig time by multiple days.
