    Repurposing Oil and Gas Wells to Geothermal Wells

    Guest: Alan Cohen, Technical Director, Gulf Offshore Research Institute & Susan Nash, Director of Innovation and Emerging Science and Technology AAPG Publication Date: May 3, 2026 🎙️Episode Highlights In this episode of Geothermal Unleashed, Elizabeth Cambre speaks with Alan Cohen and Susan Nash about the emerging opportunity to repurpose oil and gas infrastructure for geothermal. Alan opens with a major milestone: the Gulf Offshore Research Institute has been awarded $20 million over five years to convert Gulf of Mexico platforms into multi‑use clean‑energy hubs integrating geothermal, hydrogen, aquaculture, and critical‑minerals recovery. Susan then brings her deep expertise in geology, economics, and technology transfer to explain the practical realities of well conversion—from produced‑water heat and casing size to cement integrity, corrosion, and mineral‑estate regulations. She also highlights lessons from DOE‑supported pilots, including Oklahoma’s district‑heating project, and the growing role of AI in screening wells with incomplete or inconsistent data. Together, the conversation shows how thoughtful engineering and policy can transform aging hydrocarbon assets into scalable geothermal solutions both onshore and offshore. ⚠️ Disclaimer The views, opinions, and content expressed in this podcast are solely my own and do not reflect the views or opinions of Vallourec or its affiliates.
