  • Preferential fragmentation of charge case during perforating
    Patent number: 11649703
    Abstract: A perforating apparatus and method are disclosed wherein voids and inclusions may be configured to promote fragmentation of the charge case into pieces of less than a target size. In one example, the charge case of a shaped charge has a plurality of inclusions of a material interspersed with a plurality of voids of the material to promote fragmentation of the charge case. The inclusions and voids may be disposed along the periphery, such as along a mounting flange. In some examples, the voids may be holes of any of a variety of shapes, geometries, and positioning formed in the parent material of the charge case. In other examples, pieces of hardened material may be embedded in the parent material of the charge case to displace the parent material as well as to initiate probable locations of fragmentation.
