"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.

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.

Digital Twins and Generative AI in Subsurface Geophysics
"Generative modeling is a game-changer. We can now capture high-dimensional statistics that we could never have captured in the past."
Felix Herrmann explains how digital twins and generative AI are reshaping subsurface geophysics. He highlights the importance of open-source tools, multimodal data, and uncertainty-aware models for better decision-making in energy and storage projects. By combining physics with AI, his work shows how geophysics can move beyond silos and create more reliable and efficient solutions.
KEY TAKEAWAYS
> Digital twins informed by multimodal data can reduce uncertainty and improve reservoir management.
> Open-source tools and agreed benchmarks are essential for accelerating innovation in geophysics.
> Combining physics-based models with generative AI creates robust, practical solutions for complex subsurface challenges.

GUEST BIO
Felix J. Herrmann earned his Ph.D. in engineering physics from Delft University of Technology in 1997, followed by research appointments at Stanford and MIT. He later joined the University of British Columbia faculty in 2002 and moved to the Georgia Institute of Technology in 2017, where he is the Georgia Research Alliance Scholar Chair in Energy with cross-appointments across multiple schools.
Dr. Herrmann leads a cross-disciplinary research program in computational imaging, spanning seismic and medical applications, and is recognized for innovations in machine learning, optimization, and high-performance computing that have reduced costs in seismic data acquisition and imaging. A past SEG Distinguished Lecturer and recipient of the SEG Reginald Fessenden Award, he directs the Seismic Laboratory for Imaging and Modeling and co-founded the Center for Machine Learning for Seismic (ML4Seismic) to advance AI-assisted seismic imaging and reservoir monitoring through industry collaboration.
