Repurposing inactive wells into geothermal is a valuable proposition in the energy transition. This session will invite papers focused on repurposing oil and gas wells into either direct geothermal use or electricity. Additional focus will be on tecno-economical and operational aspects of repurposing technology. We will explore learnings that have helped the development of O&G, in particular unconventionals, rom fiber optics to automated data ingestion and processes. Field cases will be presented as an example of how they can help on the benefit of Geothermal (EGS) development.
