ABSTRACT:
A system for perforating a well with an annulus pressure firer is provided by the present invention. A pressure responsive means is positioned in a tubing string uphole a packer and includes a piston movable in response to a pressure differential between the upper annulus pressure and the pressure inside the tubing string. The movement of the piston is transferred through a second, concentric tubing string to a firing head on a perforating gun below the packer. The system includes a means for simultaneously decoupling the concentric tubing strings below the packer to drop the perforating gun to the bottom of the well.
