Eavor Announces Significant Drilling Performance Gains at Geretsried Geothermal Project

Drilling Breakthroughs at First Commercial Project Validate Eavor-Loop™ as Scalable, Cost-Competitive Baseload Energy

Calgary, AB — October 28, 2025 — Eavor Technologies, the advanced geothermal technology company, today released a detailed white paper at the Geothermal Rising Conference proceedings in Reno. The paper highlights substantial operational improvements and technological innovations achieved during the drilling of the company’s first commercial project, located in Geretsried, Germany. The project is a key milestone for scalable closed-loop geothermal energy and shows that ongoing innovation and learnings will transform the economics of closed-loop geothermal globally.

The paper presents a comprehensive review of drilling performance across multi-lateral sections, validating the commercial viability and scalability of the Eavor-Loop™ technology for global markets.

Key performance highlights:

• 50% reduction in drilling time per lateral and 3x improvement in bit run lengths, thanks to iterative designs and operational improvements.
• Deployment of enabling technologies like Insulated Drill Pipe (IDP), Active Magnetic Ranging (AMR), and Rock-Pipe™ sealant, which together reduce cost, improve precision, and extend reach in high-temperature environments.
• Lessons learned from sidetracking and intra-lateral hydraulic communication challenges that are now informing next-generation drilling strategies.
• A path to 35% more energy output per loop, with implications for geothermal scalability across Europe and beyond.

Technology and Innovation highlights:

• Insulated Drill Pipe (IDP): IDP is a critical tool for adapting existing oil and gas directional tools to perform in hotter and harsher geothermal environments. Since wellbore intersections require precise directional control, IDP is a core enabling technology for Eavor-Loop™ development.
• Eavor-Link™ Active Magnetic Ranging (AMR): Implementing the proprietary ranging system reduced the time dedicated to wellbore intersection and ranging activities by more than 80% compared to conventional wireline methods.
• Rock-Pipe™ Sealant: Eavor’s proprietary sealing methodology was used to seal the open-hole laterals, reducing well construction costs by over 40% compared to cemented casing.

“The advancements and lessons learned at Geretsried are translating into a competitive Levelized Cost of Heat (LCOH) along with a significant increase in energy output potential for future projects,” said Jeanine Vany, co-founder and Executive Vice President of Corporate Affairs at Eavor. “Coming down that initial learning curve and proving the technology at Geretsried, provides additional confidence for Eavor-Loop™ to scale globally as a source of reliable, flexible, carbon-free energy. These advancements bring Eavor closer to fulfilling our mission of enabling local clean energy autonomy, everywhere.”
