Finding Geothermal Energy:

Prospecting and Resource Characterization



Geothermal energy is being successfully mined and converted to electricity throughout the world today, though it accounts for only a small fraction of total annual energy production. A semi-renewable energy source, it has penetrated public consciousness as advances in research, exploration, and technology increase the viability of geothermal energy as an alternative to fossil fuels. Our geothermal workgroup focuses on applying near-surface geophysical methods to detect and image potential resources. Geoelectrical methods are mainly used, as these are sensitive to the unique electrical properties of Earth materials found in geothermal regions. Additionally, gravity data and microseismicity are also frequently considered, to help provide complementary information. The lab's geothermal workgroup has extensive experience in geothermal prospecting and is currently involved with the Organization of American States, conducting feasibility and exploration studies in several Caribbean nations.
