Abstract: A method of operating an isolation valve in a wellbore includes: deploying a work string into the wellbore through a tubular string disposed in the wellbore. The work string comprises a deployment string, a shifting tool, and a bottomhole assembly (BHA). The tubular string comprises the isolation valve and an actuator. The method further includes rotating the actuator using the shifting tool, thereby opening or closing the isolation valve. The isolation valve isolates a formation from an upper portion of the wellbore in the closed position.

Abstract: A method of drilling a wellbore includes drilling the wellbore through a formation by injecting drilling fluid through a drill string and rotating a drill bit. The drill string includes a shifting tool, a receiver in communication with the shifting tool, and the drill bit. The method further includes retrieving the drill string from the wellbore through a casing string until the shifting tool reaches an actuator. The casing string includes an isolation valve in an open position and the actuator. The method further includes sending a wireless instruction signal to the receiver. The shifting tool engages the actuator in response to the receiver receiving the instruction signal. The method further includes operating the actuator using the engaged shifting tool, thereby closing the isolation valve and isolating the formation from an upper portion of the wellbore.

Abstract: DIFFERENTIAL PRESSURE INDICATOR FOR DOWNHOLE ISOLATION A differential pressure indicator (DPI) (40) for use with a downhole isolation valve (50) includes a tubular mandrel (41m) for assembly as part of a casing string (11) and for receiving a tubular string (5). The mandrel (41m) has a stop shoulder (42h) and a piston shoulder (43p). The DPI (40) further includes a tubular housing (41h) for assembly as part of the casing string (11) and for receiving the tubular string (5). The housing (41h) is movable relative to the mandrel (41m) between an extended position and a retracted position and has a stop shoulder (44h) and a piston shoulder (44p). The DPI (40) further includes a hydraulic chamber (46c) formed between the piston shoulders (43p, 44p) and a coupling (46c) in communication with the hydraulic chamber (46c) and for connection to a sensing line (37s). The housing (41h) is movable relative to the mandrel (41m) and to the extended position in response to tension exerted on the DPI (40). ________________ -3/6 _ _ _ _ _ _ _ _ 46f 44 u 4 7a 42 41 m 42h 4 44h 43u4m 44 44p 444 7b 43p, -61 46c 41 h if 47c 43m 44b 45 44s 43s 45u 43b 47d __ _ _ _ _ _ _ _ _ _ __ _ _ _ _ _ _ _ _ _ _ 45h 45b 47e
