Seismic and borehole measurements provide significant information about HDR/HWR reservoirs that is useful for reservoir development, reservoir characterization, and performance evaluation. Both techniques have been widely used during all HDR/HWR development projects. Seismic measurements have advanced from making passive surface measurements during hydraulic fracturing to making passive observations...
Seismic signals produced while drilling a Hot Dry Rock (HDR) geothermal well in Soultz-sous-Foret (France) were detected using a 4-component seismic detector and two single-component detectors in the granite basement. The recorded signals had a signal-to-noise ratio of around 8dB with respect to the background noise and show relatively high spectral whiteness. Results from three-dimensional hodogram...
