Geophysics in Geothermal Exploration

49 1. Overview of the different geothermal systems: role of geophysics geochemical surveys, geophysicists can develop models of geothermal systems that help guide drilling decisions and reduce financial risk. Geothermal energy offers a unique and promising solution to meet society’s heating, cooling, and power needs. By understanding different geothermal systems and employing advanced geophysical techniques, we can harness this sustainable energy more effectively. Geophysics provides the tools to explore and define these hidden geothermal resources, giving us the insight to tap into the Earth’s heat with precision and efficiency, ensuring that geothermal energy continues to play an essential role in a sustainable energy future.
