Abstract:
A technique facilitates hanging of a liner in a borehole. According to the technique, a liner hanger and a liner may be deployed downhole into a borehole. A wellbore anchoring device of the liner hanger is initially actuated to engage a surrounding surface and to resist downward movement of the liner. Additionally, a hold down anchor is subsequently actuated to resist upward movement of the liner. The hold down anchor may be released via mechanical manipulation of the liner hanger.

Claim (Index 10):
A method, comprising:\n moving a liner hanger and a liner into a wellbore with a liner hanger running string; hydraulically actuating a wellbore anchoring device against a surrounding casing to resist downward movement of the liner in the wellbore; mechanically manipulating the liner hanger running string to unlock a retention mechanism retaining a hold down anchor in an unactuated position; using a spring to mechanically actuate the hold down anchor so as to resist upward movement of the liner; and removing the liner hanger running string.
