Abstract:
To operate a device for use in a well, a counter mechanism is provided that is actuatable by pressure cycles to an active position that allows actuation of the device to a target state. A position retention mechanism is coupled to the counter mechanism to maintain the counter mechanism in the active position once the counter mechanism has been incremented by the pressure cycles to the active position.
