DOE Funding Targets Conversion of Oil Wells to Geothermal Assets

The Department of Energy has established the Wells of Opportunity (WOO): Amplify II & ReAmplify funding program to commercialize geothermal energy production from existing hydrocarbon fields, targeting the nation's vast inventory of oil and gas wells for renewable energy conversion.

The program addresses two distinct technical pathways for geothermal extraction within existing infrastructure: abandoned well retrofits and co-production systems that capture heat from active hydrocarbon operations. In co-production scenarios, oil and gas wells encountering extremely hot water can harness that thermal resource to generate electricity for immediate use or grid storage.

Scale of the Infrastructure Opportunity

Oklahoma and Texas alone contain more than 800,000 historically drilled and abandoned oil, natural gas, and exploratory wells. Nationally, the United States has between 2 and 3 million disused oil wells, with over 500,000 assessed as suitable for geothermal energy production.

The University of Oklahoma received DOE funding under project number DE-EE0009962 for "Intelligent Repurposing of Hydrocarbon Wells System to Harness the Geothermal Potential of Oklahoma Sedimentary Basin." The research initiative exemplifies the federal approach to leveraging existing well infrastructure rather than requiring greenfield development.

A DOE-funded project at Blackburn field aims to demonstrate commercial viability by generating at least 1 megawatt from existing oil and gas wells through a pilot program. The project represents a critical proof-of-concept for scaling well conversion technologies across broader geographical areas.

Technical Implementation and Applications

Enhanced Geothermal Systems (EGS) leverage oil and gas drilling technology to access heat from deep rock formations for continuous clean energy production. Unlike conventional geothermal installations limited to specific geological regions, closed-loop geothermal systems use modern hydrocarbon extraction techniques to create artificial permeability in previously inaccessible areas.

Geothermal energy from retrofitted oil wells serves multiple end-use applications beyond electricity generation, including direct heating and cooling for institutional facilities such as schools. This flexibility in deployment makes well conversions particularly attractive for distributed energy applications in rural areas where hydrocarbon infrastructure is already established.

Regulatory Framework and State-Level Progress

Oklahoma state legislative bodies are considering bills to formalize processes for companies to acquire abandoned oil and gas wells specifically for geothermal energy conversion or underground energy storage. One project in Oklahoma has already secured the first state permit for converting oil and gas wells to geothermal purposes, establishing regulatory precedent for future conversions.

The Bureau of Land Management updated its geothermal resources leasing and unit agreement regulations to implement provisions from the Energy Policy Act of 2005, providing federal oversight structure for geothermal development on public lands. The Department of Interior maintains an energy policy framework that balances conventional and renewable resource development across federal territories.

Market Context and Scaling Projections

A 2024 Department of Energy analysis projects that next-generation geothermal power could deliver 90-300 gigawatts of capacity in the United States by 2050. This projection encompasses both conventional geothermal development and well conversion technologies under active DOE funding.

California currently accounts for two-thirds of U.S. geothermal power production, with initial commercial development concentrated around The Geysers in northern California. The geographic expansion enabled by well conversion technologies could significantly redistribute geothermal generation capacity across hydrocarbon-producing regions.

Looking at the broader energy transition context, this development pattern echoes what we witnessed during the early commercial internet buildout in the 1990s—existing telecommunications infrastructure provided the foundation for rapid scaling, rather than requiring entirely new physical networks. Oil and gas wells represent a similar infrastructure substrate for geothermal deployment.

Corporate Energy Sector Engagement

Major hydrocarbon companies are integrating geothermal development into their energy portfolios alongside carbon management initiatives. Chevron is developing a geothermal project in Weepah Hills, Nevada, while also investing in carbon capture technologies through companies like ION Clean Energy.

ExxonMobil has established net-zero emissions targets for Scope 1 and 2 operations by 2050, with accelerated timelines for Permian Basin unconventional assets by 2030. These corporate commitments create potential demand for well conversion technologies as companies seek to monetize existing assets while meeting emissions reduction goals.

International Research and Development

Academic research extends beyond domestic applications, with studies evaluating well conversion feasibility in international markets including the Middle East and Canada. A University of Alberta analysis modeled economic feasibility for retrofitting disused wells on large Alberta ranch properties for geothermal heating applications.

Research initiatives examine cost-benefit dynamics comparing geothermal levelized cost of electricity (LCOE) with other renewable sources including wind power. These economic assessments inform scaling decisions for well conversion technologies across different market conditions and resource availability.

The convergence of federal funding, state regulatory frameworks, and private sector engagement suggests well conversion technologies are transitioning from research phase to commercial deployment. The DOE Wells of Opportunity program provides the institutional support structure needed to validate technical approaches and establish market confidence for broader industry adoption.
