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 connects to a respective perforating gun. The tandem sub has an inner bore, and an electronic switch assembly residing within the inner bore. A contact pin also resides within the inner bore of the tandem sub, with the contact pin having a head that extends into the electronic switch assembly and is configured to transmit instruction signals from the surface. A dart is provided near the first end of the tandem sub, with the dart having a base portion and a tip. The dart resides within an end plate, wherein the base portion has an outer diameter that is greater than an inner conduit of the end plate. The dart is configured to seal against the inner bore of the end plate in response to a pressure wave generated by detonation of charges in an adjacent perforating gun, thereby sealing off the tandem sub.
