A new treating procedure which involves both hydraulic fracturing and acidizing has proved to be highly successful in stimulating the Desert Creek Formation in Utah. Production increases obtained with the technique surpass any previously obtained. Basically, the treatment is a fracture treatment using extremely viscous water-in-oil dispersions. High strength hydrochloric acid is then used to etch the fracture faces to gain conductivity. No propping agents are used. This technique is similar to treatments used in deep, massive carbonates except for the fracturing fluid. The viscous dispersion not only provides longer and wider fractures, but acts to retard the acid and allow deeper penetration. The procedure for the new fracture-acidizing technique is presented, and the probable reasons for its success are discussed. Well histories of Desert Creek wells are presented to show comparative results of different types of stimulation treatments in this formation.
