Repurposing Abandoned Oil and Gas Wells for Geothermal Applications Josiane Jello, Tugce Baser



This paper focuses on providing insights and knowledge on repurposing abandoned oil and gas wells for geothermal applications. Abandoned wells emit alarming amounts of greenhouse gases and pose serious health hazards and they require a thorough procedure for decommissioning for two reasons. The ordinary cement used in sealing of the wells used in decommissioning deteriorates with time and often leak harmful These obstacles can be addressed by retrofitting abandoned wells for geothermal energy utilization. This paper presents a comprehensive overview on the available conversion technologies, available case studies along with challenges and opportunities pertaining to repurposing for geothermal development. The proposed technology presents an attractive alternative that will reduce the overall costs of developing a geothermal system and decrease the negative environmental impact of abandoned oil and gas wells.
