Calgary-based Eavor has successfully deployed its proprietary Eavor-Link™ Active Magnetic Ranging (AMR) system at its pioneering closed-loop geothermal project in Geretsried, Germany—marking a major step forward in the future of scalable geothermal energy.
The Eavor-Link AMR system enables precise real-time magnetic ranging while drilling, eliminating the need for traditional wireline methods that require feeding cables several kilometres underground. This innovation has significantly streamlined both the parallel drilling and final intersection phases of the geothermal loop construction, allowing two boreholes to be drilled approximately 100 metres apart before being accurately connected underground.
“It’s an important milestone to have successfully used Eavor-Link AMR for both parallel drilling and final intersection phases, without the use of wireline at any stage,” said Matt Toews, Eavor’s Chief Technology Officer. “It’s a proud step forward in our mission to improve drilling performance and ultimately to enable geothermal anywhere.”
The technology’s ability to provide constant alignment and real-time communication between downhole sensors leads to tighter borehole proximity and faster, more accurate well placement. This not only reduces operational time—from hours or days to mere minutes—but also drives down costs and minimizes drilling risks.
“Eavor-Link AMR represents a major technical advancement in directional drilling — not only for geothermal but for a variety of use cases,” noted Eavor Drilling Manager Steve Nowe.
The Geretsried deployment follows years of development and testing, made possible through collaboration with Eavor Geretsried GmbH, Gunnar, Erdos Miller, and SLB. The system’s success in Germany strengthens Eavor’s vision of delivering efficient, scalable geothermal energy solutions worldwide.
“Eavor-Link AMR is a pivotal milestone in our technology roadmap,” added Toews. “It’s a testament to the relentless innovation and collaboration that has been part of our journey toward transforming geothermal energy.”
