Abstract:
1. A well tool, comprising: a housing; an actuator sleeve in the housing, the actuator sleeve having an internal shifting tool engaging profile; an actuator in the housing, the actuator responsive to a remote signal to move the actuator sleeve from a first position to a second position; and a dog in the housing supported to couple the actuator sleeve to the actuator when the actuator sleeve is in the first position and unsupported to allow the actuator sleeve to uncouple from the actuator when the actuator sleeve is in the second position, where the housing comprises a first internal diameter and a second, larger internal diameter, and the first internal diameter retains the dog inward in engagement with the actuator sleeve and coupling the actuator sleeve to the actuator when the dog is beneath the first internal diameter, and the dog is allowed to move outward, releasing the actuator sleeve to uncouple from the actuator when the dog is beneath the second internal diameter.
