The present invention provides an apparatus for use in perforating a well having a plurality of explosive charges. Each explosive charge is adapted to generate a perforation tunnel in the formation adjacent to the well. In one embodiment, explosive charges are oriented to create perforation tunnels that converge at a location within the formation in order to create a fracture initiation plane capable of mitigating or avoiding hydraulic fracturing complications.

An integrated detonation assembly of a perforating unit includes a detonator assembly and a charge assembly. The detonator assembly is positioned in the outer housing and comprises a bulkhead connected to the outer housing; a charge connector connected to the bulkhead, the charge connection having a connection end; a detonator carried by the charge connector; and a trigger coupled to the detonator and to a remote actuator. The charge assembly is insertable into the outer housing, and comprises a charge tube to support shaped charges therein; a charge feedthru; and a receiver. The receiver is at an opposite end of the charge tube, and has a receptacle shaped to matingly receive the connection end of the charge connector and to engage the trigger whereby, upon insertion of the charge assembly into the outer housing, the receiver is oriented and communicatively secured to the detonator assembly.

A detonation assembly of a perforating unit of a downhole tool is positionable in a wellbore penetrating a subterranean formation, and includes a charge assembly. The detonation assembly includes a detonator housing positionable in the perforating unit and having an uphole and downhole ends; uphole and downhole connections positioned at the uphole and downhole ends, respectively, of the detonator housing; a detonator positioned in the detonation housing; and a trigger positioned in the detonator housing. The trigger includes a detonation switch and a detonator contact. The detonation switch is communicatively coupled, when in use, between a remote actuator and the detonator contact. The detonator contact is positionable in the downhole connection, and has spring-loaded arms extending through openings in the downhole connection to urge electrical contact with the charge assembly whereby an electrical connection is maintained between the detonator and the charge assembly.
