Abstract
Enhanced Geothermal Systems (EGS) are an important source of sustainable energy and play a crucial role in meeting the increasing demand for eco-friendly power sources. To utilize the geothermal energy, it is essential to understand the subsurface velocity structures. We apply two-step velocity model building from 3D land surface seismic data acquired at Utah FORGE EGS site. We first apply 3D travel-time tomography to build smoothed background velocity model. Then, we apply 3D full-waveform inversion to estimate detail velocity structures using far-offset reflection data. Comparing the inverted velocity model with available well-log data, we observe distinct three depth zones, unconsolidated alluvium, consolidated alluvium and granitoids indicating better agreements with the well-log data.
