The Retrofit Revolution: How GreenFire Energy Is Turning Abandoned Oil & Geothermal Wells Into Continuous Clean Power Without New Drilling

The Retrofit Revolution: How GreenFire Energy Is Unlocking Geothermal Power Without Drilling a Single New Well By: Robert Buluma   While much of the geothermal energy sector has been focused on breakthrough drilling techniques—deeper wells, hotter reservoirs, and complex engineered systems—a quieter revolution has been unfolding in the background. Instead of chasing entirely new subsurface frontiers, one company has chosen a radically simpler question: What if the answer was already in the ground? GreenFire Energy is advancing a retrofit-first geothermal strategy that targets one of the most overlooked opportunities in the global energy transition: existing wells that are underperforming, depleted, or completely abandoned. Rather than drilling new holes into the Earth, the company is reusing the infrastructure that already exists—turning stranded assets into continuous sources of clean, baseload electricity. This approach is not just technically elegant. It may also be one of ...

Imagine a world where energy is not only clean but also consistent, dependable, and accessible worldwide. This vision is becoming a reality, thanks to an innovative partnership between Eavor Technologies and SLB (formerly Schlumberger). Together, they are pioneering a groundbreaking approach to harnessing renewable energy, promising to redefine how we produce and consume power and heat.

At the heart of this collaboration lies Eavor's revolutionary technology, the Eavor-Loop™, a closed-loop geothermal system that is unlike anything seen before. The partnership reached a critical milestone recently at Getesried, the home of the first commercial Eavor-Loop™, where the SLB and Eavor teams met to celebrate this transformative project.

What Is the Eavor-Loop™?



The Eavor-Loop™ is a closed-loop geothermal system that eliminates the traditional challenges of geothermal energy. Unlike conventional geothermal systems, which rely on tapping into naturally occurring reservoirs of hot water and steam, Eavor-Loop™ creates its own subsurface reservoir by circulating a proprietary working fluid through a network of sealed underground wells.

This fluid absorbs heat from the Earth and transfers it to the surface, where it can be used to generate electricity or provide direct heating. The system is entirely self-contained, which means:

No emissions: No greenhouse gases or harmful chemicals escape into the atmosphere.

No water use: It doesn’t depend on groundwater, making it sustainable and environmentally friendly.

No depletion: The loop ensures a steady supply of heat without exhausting the Earth's resources.

Why Does It Matter?

The Eavor-Loop™ represents a paradigm shift in renewable energy. Unlike solar and wind, which are intermittent and depend on weather conditions, the Eavor-Loop™ provides firm and consistent power and heat. This reliability makes it ideal for powering industries, homes, and even entire cities without the need for expensive energy storage systems.

Additionally, its adaptability means it can be deployed almost anywhere, unlocking geothermal potential in regions previously considered unsuitable. This global applicability could democratize access to clean energy, leveling the playing field for developing and developed nations alike.

The SLB Partnership: Accelerating Innovation

SLB brings decades of expertise in drilling and subsurface technologies to the table, making it the perfect partner for Eavor. By combining SLB's advanced engineering capabilities with Eavor's visionary technology, the two companies are pushing the boundaries of what geothermal energy can achieve.

The collaboration at Getesried, a site that symbolizes the dawn of this new energy era, showcases how partnerships between innovative startups and established industry leaders can drive transformative change.



The Benefits of This Revolution

1. Climate Action: The Eavor-Loop™ provides a scalable, low-carbon energy solution that could significantly reduce global greenhouse gas emissions.

2. Energy Security: By tapping into an infinite and locally available resource—Earth’s heat—countries can reduce their reliance on fossil fuels and imported energy.

3. Economic Growth: The widespread adoption of this technology could create thousands of jobs in drilling, manufacturing, and maintenance while boosting local economies.

4. Global Accessibility: From deserts to dense urban areas, the Eavor-Loop™ can bring energy independence to regions previously sidelined in the renewable energy revolution.

A Future Powered by Innovation

The meeting at Getesried is more than a corporate milestone—it’s a glimpse into the future. A future where energy is no longer a privilege but a universal right, where innovation leads the way to sustainability, and where partnerships like that of Eavor and SLB redefine the possibilities of human ingenuity.

Eavor has been keen on this Geothermal story and they are diamond sponsors in the innovation category for world geothermal congress who are hiring.

As the world grapples with the dual challenges of climate change and energy security, solutions like the Eavor-Loop™ shine a light on a better, cleaner, and brighter tomorrow. It’s not just about technology; it’s about transforming the very foundation of how we live, work, and power our world.

This is the revolution we’ve been waiting for, and it’s happening now. Are you ready to join the journey?

Eavor steps back from operator role in the Geretsried geothermal project

Eavor at the Crossroads: What Geretsried Really Tells Us About the Future of Closed-Loop Geothermal By Alphaxioms Geothermal Insights | May 13, 2026 For years, Eavor Technologies was the geothermal sector's most talked-about enigma. The company raised hundreds of millions of dollars, attracted backing from heavyweights including BP , Chevron , Helmerich & Payne , and Temasek , and made bold promises about a proprietary closed-loop technology that would quietly revolutionise how humanity extracts heat from the earth. But it rarely said much in public. The secrecy was, to many observers in the geothermal community, a feature rather than a bug — protecting intellectual property, managing competitive intelligence, buying time. Now, Eavor is talking. And what it is saying is worth listening to very carefully. In an exclusive interview published on May 13, 2026, by GeoExpro editor Henk Kombrink, Eavor's new president and CEO Mark Fitzgerald — who took the role in October 2025 ...

GEN Electric Grid Impact Study RFP in Framingham Massachusetts Advances Utility Geothermal Networks

GEN Electric Grid Impact Study RFP Signals a Defining Moment for Geothermal Energy Networks in the United States By: Robert Buluma The United States geothermal sector is entering a new phase, one where geothermal systems are no longer being viewed only as sources of heating and cooling, but increasingly as strategic infrastructure capable of strengthening the electric grid itself.

Rodatherm Energy: The Refrigerant Gambit

By: Robert Buluma   Rodatherm Energy has done something no other geothermal startup has attempted at commercial scale: swapped water for refrigerant in a closed-loop system. The claim is 50% higher thermal efficiency than water-based binary cycles, achieved by circulating a proprietary phase-change fluid through a fully cased, pressurized wellbore. The company emerged from stealth in September 2025 with a $38 million Series A—the largest first venture raise in geothermal history. Lead investor Evok Innovations was joined by Toyota Ventures, TDK Ventures, and the Grantham Foundation. The engineering thesis is elegant. The execution risks are significant. This is an Alphaxioms examination of both. II. The Thermodynamic Distinction Every geothermal company you've covered moves heat using water or steam. Rodatherm moves heat using a fluid that boils and condenses inside the wellbore. In a conventional closed-loop water system (Eavor's model), water circulates as a single-phase liq...
