Abstract
The present invention provides a method of widening or extending fractures in a subterranean formation which intersect a wellbore to enhance the flow of fluids from the formation. The enhancement is achieved by introducing an explosive gas comprising a gaseous oxidizer and a gaseous fuel and optionally a quantity of inert gas into at least one fracture intersecting the wellbore and then detonating the explosive gas. The detonation produces a pressure wave which passes down the length of the fracture. The pressure wave can cause the fracture to extend and can cause the face of the fracture to yield whereby rubble is produced within the fracture which can prop the fracture in an open position. Identical application of the method can be used to rubblize a formation for solution mining of minerals of said formation.
