Abstract
The liner assembly and method includes lowering a liner, liner hanger, liner hanger setting tool, liner packer, and liner packer setting tool into the borehole on a work string. The liner hanger is set either hydraulically or mechanically using the liner hanger setting tool at the option of the operator. The liner is then cemented within the borehole and the liner packer setting tool is used to set the liner packer either hydraulically or mechanically at the option of the operator. The liner packer setting tool includes an actuator assembly mounted on the exterior of a tubular body. The actuator assembly includes an actuator member having a contact member which engages the packing element on the liner packer such that upon movement of the contact member with respect to the liner packer, the packing element on the liner packer is compressed to sealingly engage the cased borehole. The actuator member is sealed from the fluid pressure within the borehole until the liner packer is to be set. The contact member may be actuated either mechanically or hydraulically or may be actuated hydraulically and mechanically.
