ABSTRACT:
A method and apparatus for well perforations and fracturing operations includes a shaped charge having a generally spherical container, a conical liner positioned therein, an explosive substantially filling the container around the liner, and a booster charge in the form of an annular wafer of compressed high speed explosive positioned against the wall of the container in axial alignment with and adjacent the apex of the liner. The outside diameter of the booster charge is at least as large as one-half the diameter of the base of the conical liner and in proximity to a primer cord positioned in contact with the exterior of the container. The spherical container is composed of a frangible material, and it is positioned in a cylindrical carrier also composed of a frangible material which disintegrates upon detonation of the explosive. A secondary explosive of slower detonating speed than the primary explosive is packed around the shaped charge container in the carrier, and the carrier is sealed at both ends.
