Abstract
A system is provided for performing multiple operations on a well in response to multiple fluid pressure increases. The system includes first and second pressure actuated firing heads and a source of actuating fluid pressure for the firing heads. A first selective communication device is provided for isolating the second firing head from the source of actuating fluid pressure until after the first firing head has been actuated and for then communicating the second firing head with the source of actuating fluid pressure in response to actuation of the first firing head. This system is particularly adapted for allowing pressure testing of a well upon a first fluid pressure increase, followed by perforation of the well upon a second fluid pressure increase.
