Board of Regents, NSHE, obo University of Nevada, Reno (hereafter UNR) would utilize DOE and cost share funds to apply high resolution ambient seismic noise seismic interferometry to Enhanced Geothermal Systems (EGS) favorability characterization at the Dixie Valley Geothermal System in Nevada. UNR is developing a new exploration technology which includes application of seismic interferometry and seismic array signal processing techniques developed for nuclear monitoring to conventional geothermal seismic reflection surveys. This project would use this technique to evaluate the usefulness for EGS exploration of seismic parameter information in comparison with information from and at the same scale as other geophysical exploration methods deployed in the same project area. Project activities include (1) new data collection, (2) use of seismic event waveforms from AltaRock Energy Inc. (2014) seismic surveys to investigate the possibility of extracting supplementary seismic parameter information, and (3) generation of new EGS favorability maps by factoring the proposed higher seismic resolution data to compliment and improve the previous investigations.
