Converting Non-Producing Oil and Gas Wells for Geothermal Energy Production

Geothermal energy has gained significant attention over the years as a renewable alternative to traditional fossil fuel energy systems. Non-producing oil and gas wells may be repurposed as geothermal wells for heating or electricity generation. Converting non-producing oil and gas wells into geothermal energy production can offset the costs of drilling new geothermal wells and provide an incentive for remediating non-producing well sites. However, the absence of regulations for geothermal well conversion in North America and Europe leaves many unresolved questions about the ownership and financial responsibility of the wells. Here, we present an analysis of non-producing well attributes, such as depth, location, type, and proximity to geothermal boreholes, and well integrity indicators, including methane emission measurements and surface casing vent flows, to identify suitable sites for geothermal energy conversion in the United States and Canada. We also explore various case studies of geothermal well conversion from around the world, comparing different geothermal systems and their applicability to Canada. The findings from this research will be useful in supporting policy development and regulatory frameworks for geothermal conversion projects in Canada, the United States, and around the world.
