OSTI ID:888533
Well 18 is a production well in the southern zone of Los Azufres geothermal field in México (see Figure 1). The well is located on the eastern flank of the drilled area, and produces a steam/water mixture from a depth of 1200-1250 m. A 19 hour pressure buildup test that was carried out in March 1986, is the subject of this paper. It is part of work reported by Sánchez-U. (1986) at the Geothermal Training Programme in Iceland. The permeability-thickness product of well 18 in Los Azufres field was determined 5.4 dm from a Horner plot. The well was found to be intersected by a fracture, as evident from the slope on a log-log plot at early time, and a skin value of -5.3. The overall pressure buildup of the well was found to be typical for double-porosity reservoir behavior, having a storativity ratio of 0.1. An outer boundary behavior was observed in the pressure buildup data. 1 tab., 6 figs., 14 refs.
