Vann, R R; Brieger, E F

A method is described of perforating two spaced-apart formations, which consists of: positioning a first perforating gun in a borehole adjacent to a first formation and a second perforating gun in the borehole adjacent to a second formation; detonating the charges of the first gun to create a pressure shock wave, the pressure shock wave being generated by application of the explosive force from firing the first gun to a movable wall closing one end of a column of fluid; directing the pressure shock wave to means for detonating the charges of the second gun; and detonating the charges of the second gun in response to the pressure shock wave. An apparatus is described for completing a well, comprising; first perforating means for perforating one portion of the well; second perforating means for perforating another portion of the well; means for transmitting a fluid pulse upon detonation of the first perforating means; and means for receiving the fluid pulse to actuate the detonation of the second perforating means.
