摘要: An apparatus for use in a subterranean well includes downhole energy source, first switch, second detonator, controller and controller. The switch has predetermined state to transfer from the source. A detonator receives source when switches are concurrently states. independently detects stimulus that is transmitted surface of causes enter based on detection by
