Abstract: The present Invention relates to a device and a method for perforating downhole casings. The method comprises the steps of arranging a device (1) comprising a pipe section (3) on a drill string, running the device (1) into a bore hole to a desired location in the well, dropping a ball (7) down through the drill string down to the device (1), where the ball (7) rests in a ball seat (5), thus blocking fluid communication between the inside and the outside of the device (1), whereby the pressure on the Inside of the d rill string and the device (1) is pumped up to a first pressure level and a first sequence of pressure rises and pressure reliefs is carried through within a first pressure level Interval, whereby a firing system (4), arranged to react to said first sequence of pressure rises and pressure reliefs, triggers a charge or group of charges (2), whereby the charge or group of charges (2) punches one or more holes through a surrounding casing wall, driving the pressure on the inside of the drill string further up to a second level causing a rupture disc (8), arranged in an opening (10) in the pipe wall to the pipe section (3) somewhere above the ball seat (5), to burst and establishing a fluid communication between the inside and outside of the drill string through the opening in the pipe wall of the pipe section (3), and to start a circulation In the well by pumping a fluid down through the drill string and out through the opening which is created when the rupture disc (8) bursts.
