A drilling well pulling tool comprising a longitudinal body having an inner cavity. A sleeve is slideably disposed about a portion of the longitudinal body, the sleeve moveable from a first position to a second position. A dog member is retractable from an extended position to a retracted position relative the body when the sleeve is moved from the first position to the second position. A release lug abuts and resists movement of the sleeve from the first position, the lug releasable to the inner cavity thereby permitting slideable movement of the sleeve. An electromechanical actuator releases the release lug upon actuation.
