ABSTRACT:
The present invention relates to an innovative, safe, explosive device. The device has many potential fields of utility, including, but not limited to mining, oil exploration, seismology, and particularly to shaped charges. These shaped charges may be used as a well perforation system using energetic, electrically-activated reactive blends in place of high explosives. The reactive blends are highly impact inert and relatively thermally inert until activated. The proposed system requires no conventional explosives and it is environmentally benign. The system and its components can be shipped and transported easily with little concern for premature explosion. It also needs no special handling or packing. The performance in oil and gas well perforation can be expected to exceed that of conventional explosive techniques.
