An acidizing technique has been developed for treating carbonate reservoirs that will give deep penetrating fractures with high flow capacity. The technique uses the principle of hydraulic fracturing with a thickened fluid. Instead of using a proppant in the fluid, acid is used to produce flow capacity by controlled etching of the fracture system. The advent of complex fracturing fluids led to the idea of using a viscous pad to control leak off of acid for more fracture height and width. A typical computer-designed treatment is presented. Deep, hot wells, which could not be successfully stimulated by conventional means, have responded to such treatment. The process can, in many cases, be directly substituted for hydraulic fracturing.
