  • High energy fracking device for focused shock wave generation for oil and gas recovery applications
    Patent number: 11976543
    Abstract: A fracking device (100) for generating shock waves in a well bore (102) comprises a fracking gun (110). The fracking gun (110) includes a cartridge (200) having a hollow cavity and a cylinder (202) disposed inside the hollow cavity of the cartridge (200). The cylinder (202) has a first chamber (210) and a second chamber (212). The first chamber (210) includes a plurality of explosive charges (206) positioned on an inner surface of the cylinder (202), wherein each of the explosive charges (206) contains an explosive mixture comprising hydrogen and stoichiometric oxygen in a predetermined ratio. The second chamber (212) contains a combustion-neutral gas. The first chamber (210) is separated from the second chamber (212) by a diaphragm (214).
