A method is described for fracturing a substerranean earth formation to stimulate the production of fluid from the formation wherein a wellbore extends at least to the formation from a surface point. The wellbore is provided with casing means forming a substantially fluid tight interior space, the method comprising the steps of: providing perforating means for perforating the casing means at a predetermined zone of the formation to provide for low of fluids between the formation and the wellbore and placing the perforating means at the zone, filling at least a portion of the wellbore with a compressible fracturing fluid comprised of a liquid containing dispensed quantities of gas and having a solid proppant dispersed therein; raising the pressure of the fracturing fluid in the wellbore to a predetermined pressure greater than the pressure required to hydraulically extend a fracture in the formation at the zone; and actuating the perforating means to form apertures in the casing means and concomitantly generating a high gas pressure within the fluid whereby the pressurized fracturing fluid at the predetermined pressure is allowed to flow into the formation under decompression forces. This is done to fracture the formation with a quantity of the fracturing fluid and to prop fractures in the formation open with the proppant.
