Abstract
A resettable mechanism and a method of controlled actuation of a hydraulically operated downhole tool to allow selective operation of the downhole tool in a wellbore. The resettable mechanism provides an inner sleeve member which is longitudinally moveable between a first and second position which opens and closes a fluid pathway to at least one actuation port on the downhole tool. Movement of the inner sleeve member is controlled via an indexing mechanism operated by drop balls. An embodiment of a casing recovery system is described mechanism operated wherein a downhole pulling tool is selectively actuated so as to prevent operation of the pulling tool while a hydraulically operated casing cutter is cutting casing.
