Abstract:
A method of in-situ rock permeability enhancement involves penetration of a target formation by a well, downhole injection of a fluid, action on the fluid by static pressure and shock waves of a specific pattern transmitted downhole along a fluid waveguide and directed to the target formation from a wave reflector, thereby generating dilatant decompaction of the rock. The action on the fluid by static pressure and by shock waves occurs simultaneously, so that static pressure exceeds the capillary pressure in pores of the most common size in the decompacting rock by no less than 1.3 times. The selected shock wave amplitude is equal to or greater than the compressive or tensile stress necessary for dilatant decompaction of the rock. The proposed technical solution will make it possible to improve the efficiency of the in-situ permeability enhancement and rock decompaction process while reducing energy consumption and operating costs.

Claim (Index 3):
