Adapt or Be Left Behind: Lessons for the Next Generation of Geophysicists

"Geophysics plays a central role in this energy transition because it provides the tools and insights needed to understand, manage, and optimize subsurface resources. These resources are critical for both traditional and renewable energy systems." Geophysics is essential for geothermal energy, carbon storage, hydrogen storage, and critical minerals. Joël Le Calvez and Erkan Ay explain how methods like multi-physics workflows and distributed acoustic sensing are improving reliability, scalability, and safety. They also highlight the skills and mindset geophysicists need to succeed in a rapidly changing energy landscape.

KEY TAKEAWAYS > Geophysics provides the foundation for safe, efficient, and scalable use of subsurface resources in the energy transition. > Multi-physics workflows and DAS technologies reduce uncertainty and improve monitoring of geothermal and storage projects. > Future geophysicists must combine technical expertise with adaptability, collaboration, and field experience. GUEST BIOS Joël Le Calvez is Principal Geologist at SLB, where he develops software for processing, visualization, and interpretation of microseismic monitoring data. His work supports applications ranging from hydraulic fracture treatment to CO₂ sequestration and geothermal injection, using downhole, shallow wellbore, and surface arrays. Before joining SLB, Joël contributed to research at the Bureau of Economic Geology’s Applied Geodynamics Laboratory and at Etudes et Recherches Géotechniques. He holds a Ph.D. in salt tectonics, an M.Sc. in geosciences, and a B.Sc. in physics. Erkan Ay is an accomplished geophysicist with more than 18 years of international experience across oil and gas, carbon capture and storage, and academic research. He is recognized for advancing techniques in microseismic monitoring, DAS, 4D VSP, and seismic-while-drilling. Erkan’s work integrates seismology and petrophysics to better characterize complex subsurface structures. Currently, Erkan serves as Chair of the SEG Research Committee and Vice Chair of the SEG IMAGE 2026 Technical Committee, guiding collaborative efforts to advance geophysics for sustainable energy solutions.
