Experimental study on an alternative oil stimulation technique for tight gas reservoirs based on dynamic shock waves generated by Pulsed Arc Electrohydraulic Discharges

► Development of a technique to increase the permeability of rock with dynamic loads. ► Tests with single shock exhibit increases of permeability by two orders of magnitude. ► Permeability increases with the number of shocks with moderate energy. ► X-ray tomography correlates macro-cracking with the increase of permeability.
