SHOCK WAVE ASSISTED FRACKING USING OXY-HYDROGEN GAS MIXTURE DETONATION

摘要

An oxy-hydrogen gas mixture based fracking apparatus for rejuvenating depleted petroleum wells is disclosed. The apparatus includes an outer vessel comprising a first chamber and a second chamber separated by a valve. Metal electrodes are incorporated into the first chamber and are immersed in an electrolyte solution. Oxy-hydrogen gas is generated within the first chamber by electrolysis of the electrolyte solution. The valve facilitates controlled movement of generated oxy-hydrogen gas into the second chamber on reaching a predetermined pressure threshold within the first chamber. An igniter incorporated into the second chamber ignites the oxy-hydrogen gas thereby generating high pressure gas. High-speed valves mounted in a circumferential manner on an outer periphery of second chamber eject the generated high pressure gas resulting in a plurality of shock waves. The shock waves are exerted onto the inner surface of the petroleum well bore thereby creating newer cracks or expanding the existing cracks.
