Abstract: A charge assembly for incorporation into a downhole tool to induce pressure at an interior of the tool during a downhole application. The assembly includes a reactive powder metals that is particularly configured of a reaction rate slower than that of a high energy explosive directed at the application. Thus, upon triggering of the explosive and downhole application in a high pressure well environment, reaction of the powder metals may serve to substantially reduce any pressure differential at the tool. As such, shock related damage due to sudden introduction of pressure differential wave to the tool may be minimized.
