Liner hanger systems
Versatile options to suit various well conditions
Well trajectory complexity, depth, pressure, temperature, and cost have increased the challenges of well construction design, planning, and operations. Long horizontal laterals in unconventional shale wells, liner drilling, extended reach wells, cemented and uncemented liners require high-performance liner hanger systems capable of: rotation to reach total depth, robust setting mechanisms tolerant of higher solids content, liner top packer sealing elements which can survive run in hole, circulating and cementing at higher rates to lift and homogenize the mud around the liner, all while controlling the equivalent circulating density (ECD) to avoid approaching the fracture gradient and damaging the formation. Once set on depth, seal integrity must be maintained through high-pressure fracturing operations in the case of some uncemented liner applications and years of pressure and thermal cycling during production.
Enhance well integrity and reduce costs in well construction with a full line of liner hanger systems, equipment, and accessories for conventional and complex well applications on land or offshore. Backed by a track record of more than six decades, SLB liner hangers, liner top packers, and mechanical and hydraulic set and release running tools are engineered to suspend, support, isolate, seal, and anchor in all types of applications and environments.
With a range of available liner hanger equipment and services, Xcelis™ high-performance liner hanger systems excel in the most challenging environments, and COLOSSUS™ liner hanger systems provide versatile option to suit various well conditions.
Enhance well stability and protect the casing with cemented and uncemented liner hanger systems that suit a wide range of well conditions.
Deploy long, heavy liners in challenging conditions—including deepwater, extended-reach, and HPHT wells—with expandable, metal-to-metal sealing for the life of the well.
Manage the most challenging thermal applications—such as geothermal or steam assisted gravity drainage—with robust liner hangers designed for wells undergoing extreme temperatures and temperature cycling.
