The geothermal reservoir well stimulation program group performed a large hydraulic fracture treatment in the well Baca 20, located in Union's Redondo Creek project area in N.-Central New Mexico. This is the highest temperature well in the world to be successfully prop-fractured to date. The treatment utilized a large cooling water pre-pad followed by a high viscosity frac fluid carrying sintered bauxite as the proppant. A nonproductive 240 ft open-hole interval, with a formation temperature of 520 F, was selected and isolated for the job. Post-stimulation tests and analyses indicate a dynamic fracture was created with a large vertical height near the well bore. A number of fracture evaluation techniques were used to analyze the job. Among these techniques were fracture mapping by monitoring the microseismic events caused by the job, down-hole treating pressure data analysis, temperature profiles, electric log surveys, production tests, and chemical tracer monitoring. The post-stimulation fluid productivity of the well is subcommercial, probably because of low formation permeability surrounding the artificially created fracture.
