|Project Title||Seismic Technology Adapted to Analyzing and Developing Geothermal Systems Below Surface-Exposed High-Velocity Rocks|
|Project Type / Topic 1||Recovery Act: Enhanced Geothermal Systems Component Research and Development/Analysis|
|Project Type / Topic 2||Geophysical Exploration Technologies|
|Project Description||Historically, areas where the Earth surface is covered by an exposed high-velocity rock layer have been locations where conventional, single-component, seismic P-waves have failed to provide usable geological information. The research will use new seismic sources that emphasize shear waves and new seismic data-acquisition technology based on cable-free data recording to acquire seismic research data across two sites covered with surface-exposed highvelocity rocks. Research tasks will involve acquiring, processing, and interpreting both conventional seismic data and multicomponent seismic data. Scientists at BEG will analyze well logs, cores, and reservoir test data to construct geological models of the targeted geology across each study site.|
|Objectives||By combining P-wave and S-wave seismic attributes, particularly attributes from the SH shear mode, with appropriate rock physics models, the research team will show how multicomponent seismic technology allows geology across geothermal prospects located beneath high-velocity rock outcrops to be imaged and exploited much better than can be done if a prospect is evaluated with only conventional P-wave seismic data.|
