ABSTRACT:
A perforating unit for high density, multiphase well perforating operations having a plurality of elongate cylindrical perforating gun barrels whose firing axes are at predetermined angles one relative to the other. A multiport top sub secures the upper ends of the barrels with the barrels parallel to each other. A cablehead on the top sub provides for support. A multiport bottom sub secures the lower ends of the barrels. A circuit in the cablehead extends through the cablehead and into the unit for use in detonation of explosive charges to be received therein.
