Zusammenfassung:Apparatus for performing multiple operations on a well in response to multiple fluid pressure increases has first (1012) and second (1006) pressure actuated firing heads and a source of actuating fluid pressure for the firing heads. A first selective communication device (1010) is provided for isolating the second firing head (1006) from the source of actuating fluid pressure until after the first firing head (1012) has been actuated and for then communicating the second firing head (1006) with the source of actuating fluid pressure in response to actuation of the first firing head (1012). The apparatus includes a well tool which is actuated by the second firing head.
