ABSTRACT:
A retrievable well lock for use within a subterranean member is used in cooperation with a tool for setting the lock. The lock will include an actuation assembly which is operable in response to longitudinal movement between portions of the lock. The setting tool will preferably include a power source within a housing assembly which can be selectively coupled to or decoupled from the lock assembly. The power source is associated with the setting tool through an activation assembly which will cause movement of a movable mandrel within the setting tool facilitating the selective actuation of the lock.
