These reservoirs offer the expansiveness of certain sedimentary formations, which means they could have the potential to support multiple geothermal plants with a single characterization effort. Additionally, stratigraphic reservoirs have been historically associated with the gas and oil industry, so existing data from exploration and production could be leveraged to geothermal projects. In fact, the resource at Steptoe Valley was first discovered during gas and oil exploration activities. The research team utilized the power of new and established geophysical imaging techniques to gain a deeper understanding of the subsurface and assess the potential for geothermal energy production. Coupling geophysical imaging with geological and geochemical findings, such as those from surface and borehole studies, proved most effective for characterizing the northern Steptoe Valley resource. The team published the data and models from the project, ensuring open access to researchers, geothermal developers, and others, expanding opportunities to leverage geophysical imaging to see beneath earth’s surface. By enhancing understanding of hidden geothermal systems, as well as showcasing the effectiveness of geophysical imaging in research, the DOE’s Geothermal Technologies Office is enabling better and more costeffective geothermal resource exploration and characterization.
