The Application Framework for Geothermal Re-Circulation Proposed for Converting Hydrocarbon Wells Into Geothermal Wells in Oklahoma

This paper presents an update on the project to repurpose depleted oil wells into geothermal wells and shares a comprehensive workflow for obtaining permitting in Oklahoma. The objective is to provide a structured approach that addresses regulatory aspects, facilitating the transformation of oil wells into efficient geothermal energy sources. The methodology involves assessing geological conditions, analyzing regulations, and developing tailored monitoring and operation plans. The results highlight Oklahoma's potential as a significant renewable energy source through geothermal means, particularly in the Arkoma Basin and Anadarko Basin. However, challenges exist, including the need for a clear regulatory framework for deep geothermal energy, hurdles in obtaining landowner agreements, and regulatory constraints on well selection for heat transfer fluid re-circulation. The study offers novel insights and practical guidelines for engineers and policymakers in geothermal energy development, contributing to the field of sustainable energy.
