TORXS Expandable Liner Hanger System

TORXS Expandable Liner Hanger System

  • The TORXS™ liner hanger system is the only expandable liner hanger system that can be run and installed conventionally, without requiring a critically timed high-pressure plug bump as the primary activation method for the hanger or packer, or for release of the running tool.

    TORXS eliminates dependence on a plug bump, because all hydraulic activations, including tool release, occur with pressure acting on a positive seal in the running tool. This minimizes the risk of poor-quality liner-to-cement bonding that can occur when a liner is ballooned with a high-pressure plug bump.

    The TORXS liner system—run on the TORXS liner running tool—can be run the same as any premium liner system.

    Upon reaching setting depth, the liner can be circulated and conditioned. A setting ball is dropped from the surface and landed on the extruding ball seat in the running tool. Applied pressure actuates the hydraulic anchor along with the swage mechanism on the running tool causing the hanger body and slips to expand outward making permanent contact to the casing string. Circulation is again established and cementing of the liner can be performed.
