Abstract: A perforation gun having a modified pin end for positioning a blast shield between adjacent guns, the blast shield electrically joining movable contact pins and propagating firing signals between while protecting against blast forces from previous explosions. The perforation guns also having a wiring port in the charge carrier and alignment pin for opening and adding detonation circuitry at time of use, positioned within the charge carrier where it is protected from damages caused by rough handling, flooding, vibrations, and blast forces.

Abstract: A perforation gun assembly comprising a plurality of guns with a box fitting at one end and a modified pin fitting at the distal end; the modified pin fitting further comprising an end cap secured to an internal charger carrier, aligning a plurality of shape charges with scallops in the gun casing; and having a pressure switch, which connects to an electrical connection point at the box end of a charger carrier in an adjacent gun. The end cap being captured between the pin of one gun and the internal edge of the mating gun to protect and channel blast force to the pressure switch.

Abstract: A gun assembly for perforating wells comprising a plurality of guns with shape charges aligned centrically by end caps having insulated connector pins for conducting electrical signals and pressure through the end caps while preventing debris from the blast of one gun from entering and damaging the electrical connections and components of the next gun. The end caps being interconnected physically and electrically by specialized intermediate subs.

Abstract: An apparatus and method for use for gun assembly for perforating wells comprising a plurality of guns with shape charges aligned centrically. The apparatus allows easier and more reliable assembly on site with more secure connections. The apparatus provides for the conducting of electrical signals and pressure through the end caps while preventing debris from the blast of one gun from entering and damaging the electrical connections and components of the next gun. The end caps being interconnected physically and electrically by specialized intermediate subs or by utilization with industry standard intermediate subs.

Abstract: An electromechanical switch for use in well perforating gun assemblies wells comprising an initial pass-through configuration where the switch passes an electrical connection from a shooting line through the switch's plunger to the neighboring gun until a pressure event acts on the switch causing the shooting line to disengage from the neighboring gun and connect to the internal detonator for subsequent firing sequence to trigger detonation.
