First Claim
Patent Images
1. A method usable with a subterranean well, comprising:
- communicating a wireless stimulus downhole in the well;
actuating a casing conveyed perforating gun in response to the communication;
downhole in the well, confirming firing of the perforating gun; and
in response to the confirmation of the firing, communicating another wireless stimulus from a transmitter integrated with a casing string uphole to indicate the confirmation.

9. A system usable with a subterranean well, comprising:
-
a casing string comprising a casing conveyed perforating gun located downhole in the well; and an apparatus to communicate a wireless stimulus downhole to the perforating gun to actuate the perforating gun; a circuit located downhole to confirm firing of the perforating gun; and a transmitter integrated with the casing string to in response to the confirmation of the firing of the perforating gun, communicate another wireless stimulus uphole indicative of the firing. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A perforating gun comprising:
-
perforating charges adapted to be embedded in a casing string section to perform a downhole function, a mechanism adapted to respond to a wireless stimulus transmitted from a surface of the well to fire the perforating charges; a circuit located downhole near the perforating gun to confirm firing of the perforating charges; and a transmitter embedded in the casing string section to in response to the confirmation communicate another wireless stimulus uphole to confirm firing of the perforating charges. - View Dependent Claims (19, 20)
