Abstract
A detonation system for a perforating gun assembly. The detonation system includes a tandem sub having a first end and a second opposing end. Each of the first and second ends is connected to a respective perforating gun. The tandem sub has an inner bore, and a switch housing residing within the inner bore. The tandem sub also has an addressable switch residing within the switch housing with the switch being configured to receive instruction signals from a surface by means of an electric line. The addressable switch is in communication with a signal transmission pin and a detonator pin. The detonator pin sends a detonation signal from the addressable switch to a detonator in an adjacent perforating gun. The wiring connections for the pins may be pre-assembled before the perforating guns are delivered to the field. The detonation system utilizes a carrier end plate, wherein the end plate and pins seal off the tandem sub from wellbore fluids and debris following detonation of explosive charges in an associated perforating gun.
