Abstract
A method of stimulating a well subsequent to the formation of perforations whereby, subsequent to the perforating, pressure is suddenly applied to the perforations at a pressure above the fracturing pressure to extend created fractures in the formation. A bridging means is utilized to isolate the upper portion of the casing from a lower portion having perforations. The casing above the bridging means is charged with a stimulation fluid. At a predetermined pressure the bridging means releases the stimulation fluid into contact with the perforations to substantially simultaneously create or initiate a fracture into the formation from each perforation.
