NOTE: These are theoretical/computer simulation tests of various methods on eight hypothetical 'model' basing-and-range geothermal systems. "The 300-meter heat flow holes are essentially useless for finding the "hidden" reservoirs. Clearly, the best results are obtained from the SP and MT surveys, with DC resistivity a close third. It is concluded that the best way to find "hidden" basin and range geothermal resources of this general type is to carry out simultaneous SP and low-frequency MT surveys, and then to combine the results of both surveys with other pertinent information using mathematical "inversion" techniques to characterize the subsurface quantitatively. Many such surveys and accompanying analyses can be carried out for the cost of a single unsuccessful deep "discovery well"."
