  • Perforation gun with angled shaped charges
    Patent number: 9145763
    Abstract: A perforation gun which provides a means to create perforations required for the hydraulic fracturing of rock formations for the production of natural gas, oil, and other oil well fluids and further comprises a gun body assembly having an inserted carrier tube to nest shaped charge canisters with built in primers, conical liner, and explosive material. The charges are positioned in various angular patterns along various phase angles to create specifically directed perforation tunnels which puncture scalloped areas of the aforementioned gun body and subsequently penetrate through the wellbore, well casing, well cement, and into the rock formations for the release and removal of natural gas, oil, and other oil well fluids after hydraulic fracturing.
