Seismic Soundoff

“The difference now is horizontal wells, faster drilling, and better geophysics. That makes today’s EGS attempts more promising than ever.” In this episode, host Andrew Geary talks with Michael Wilt and Bill Cumming, guest editors of the April 2025 The Leading Edge special section on geophysical applications to geothermal exploration and development. With decades of field experience, Bill and Michael dive into the lessons and findings from the U.S. Department of Energy's FORGE Enhanced Geothermal System (EGS) research project and Fervo's Cape Modern EGS commercial project. The interview features thoughtful back-and-forth that reveals the complexity of emerging EGS techniques. They discuss how microseismic monitoring, DAS systems, P-wave velocity models, and well design are shaping the future of EGS development. Importantly, they share practical advice for how geophysicists and students can get involved in this rapidly evolving field. KEY TAKEAWAYS > Utah FORGE and Cape Modern are shaping the practical fut
