ABSTRACT:
A method for stimulating oil and gas wells to increase production including filling the lower portion of the well above the pay zone level having exposed rock with a fracturing fluid, and sealing the well above the lower portion. A shock wave is then applied to the fracturing fluid, which, when applied thereby to the rock at the pay zone creates a stress wave in the rock having a rise time faster than the time required for sound to traverse one half the periphery of the rock at the pay zone, and having an amplitude which will fracture but not crush the rock.
