Abstract
A liner hanger running system including a liner hanger having a body including a wall defined by an outer surface and an inner surface. The body includes an opening that extends through the outer surface and the inner surface. A piston housing including a wall portion defined by an outer surface portion and an inner surface portion is spaced from the outer surface of the body to define a piston Chamber exposed to the opening. A piston is arranged in the piston chamber. A liner hanger running tool including a dog key extends into the opening and engages the piston. The dog key is selectively shiftable relative to the liner hanger to release the piston and expose the opening to a setting pressure.
