这项工作提供了对重新利用油气井生产地热能以直接供暖的技术和经济可行性的见解。评估了这种方法的潜在好处（特别是对于高度依赖化石燃料供暖的地区）和挑战，同时确定了未来发展的技术、市场和政策障碍。将油气井重新利用为地热能需要采用多学科方法，其中涉及地质学、工程和监管事务方面的专业知识。
由于与这些井相关的低温，将废弃井重新用于地热能项目发电可能会带来挑战。人们发现，此类井中的低温梯度和可用热能限制了总体发电潜力。
This work provides insights into the technical and economic viability of repurposing oil and gas wells for geothermal energy production for direct heating. The potential benefits—especially for areas that are highly dependent on fossil fuels for heating—and challenges of this approach are assessed, while technical, market, and policy barriers for future development are identified. Repurposing oil and gas wells for geothermal energy requires a multidisciplinary approach that involves expertise in geology, engineering, and regulatory affairs.
Repurposing abandoned wells for power generation in geothermal energy projects can present challenges because of the low temperatures associated with these wells. The low temperature gradients and thermal energy available in such wells have been found to limit overall power-generation potential.
