Abstract: To date, no cost effective method had been developed to estimate compressional (P), shear (S) seismic velocity models and buried fault location, which provide essential information in geothermal exploration. Although active source reflection seismic experiments provide high resolution P-velocity models and direct information on the resource availability, widespread use is costprohibitive and must be used selectively, which is difficult when no seismic information is available in the area. Thus, developing an inexpensive seismic exploration methodology and identifying new seismic parameters (attenuation, spectral and stochastic properties) to be used for geothermal reservoir characterization is essential for reducing geothermal exploration technology costs.
