Integrated liner hanger packer
Designed for high differential pressures, the SURESET™ liner hanger packer is a complete liner hanger system built on a one-piece mandrel with no internal connections. The SURESET includes a packing element, an integral packoff nipple profile, and the hanger.
The hanger may be set using a hydraulic cylinder or, in some sizes, a mechanical set option is available. Tested to the latest API 19LH standards, the SURESET packing element is available in multiple elastomer options for various applications and is activated with set down weight using a packer actuator. In addition to the internal snap ratchet, the hold-down slips keep the SURESET element in position against high differential pressures.
The hanger portion of the SURESET contains slips that are fully recessed into a special profile in the rotating body to ensure trouble-free installation and uniform load distribution in the setting section. In both the set and un-set positions, the SURESET liner hanger packer allows for high bypass, ensuring low ECDs (equivalent circulating density).
