ABSTRACT:
A method for extending fractures in underground formations obtained by controlled pulse fracturing through the use of a stabilized hydrogen peroxide solution. Controlled pulse fracturing causes radial fracturing near the wellbore. These radial fractures are further extended into the formation or reservoir when stabilized hydrogen peroxide is forced into the radial fractures. Stabilizing agents in the hydrogen peroxide react with metals mixed with a proppant in the formation causing the hydrogen peroxide to breakdown and form gas pressure sufficient to extend the radial fractures. Hydrocarbonaceous fluids are then obtained from the natural fractures in said formation via the extended fractures which contact natural fractures emanating from the wellbore.
