Fracture stimulation of Union's Baca Well 23
The DOE-sponsored Geothermal Reservoir Well Stimulation program group performed a large hydraulic fracture treatment in Baca Well 23, located in Union's Baca Project Area in Sandoval County, New Mexico, on March 22, 1981. The treatment utilized a cooling water pre-pad followed by a high viscosity frac fluid carrying a mixture of bauxite and resin-coated sand as the proppant. A 231-foot interval from 3300 feet to 3531 feet was isolated for the job and was nonproductive prior to stimulation. Post-stimulation surveys and production tests indicate a vertical fracture at least 300 feet in height and more than 300 feet in length was successfully created. After stimulation, the well produced 120,000 lb/hr total mass flow at a wellhead pressure of 45 psig. An analysis of the pressure buildup data yielded an average reservoir permeability-thickness of 2500 md-ft.
