Abstract: A shaped charge retention and barrier clip according to the invention includes a barrier ring means for preventing damage to the interior of a perforating gun, and retention means for securing the barrier ring means and the shaped charge to a carrier strip disposed in the perforating gun.

Abstract: In the representative embodiment of the present invention disclosed herein, a plurality of generally-cylindrical modular bodies are tandemly assembled within a typical end-loaded perforating carrier. A generally-longitudinal passage containing a detonating explosive is arranged in each of the modular bodies so that, when the bodies are tandemly assembled in a carrier, these passages will collectively define a continuous passage through which detonation-inducing forces can be transmitted. Shaped charges are mounted in at least some of the modular bodies and positioned to be fired upon detonation of the explosive in the continuous passage.
