INTERVIEW, Geretsried and Beyond: Eavor’s Blueprint for Reliable, Sustainable Energy

Robert Buluma :  Alphaxioms Responses were provided by Jeanine Vany, Executive Vice-President of Corporate Affairs, Eavor . Can you explain the key technological advancements in the latest iteration of the Eavor-Loop™ system? We have made a number of technological advancements at our project in Geretsried Germany . This includes innovation and learning resulting in dramatic improvements in our drilling performance and we’re proud to talk about our technology. For example, Eavor recently announced successful implementation of our in-house AMR (active magnetic ranging) tool which makes drilling more accurate and efficient. Eavor-Link™ AMR uses magnetic ranging while drilling to maintain constant alignment as it drills two wells at approximately 100 metres apart before they are intersected to create a continuous geothermal loop, which is then sealed with Eavor’s proprietary Rock-Pipe™ formula. With real-time data transmission between downhole sensors, the technology ensures tighter bo...

Driving the UK Toward Net Zero: Chris Sladen on Geothermal’s Untapped Potential

Alphaxioms, we talked to Chris Sladen about his involvement in geothermal both in the UK, and globally By:  Robert Buluma Chris, please begin by explaining a little about yourself, and why you have a passion for geothermal? I have spent over 45 years involved in energy. Following undergraduate studies in geology at Southampton University, and a PhD in sedimentology at Reading University, I joined the energy sector in Aberdeen in 1980. It was a fascinating era when it seemed like at least one giant oil & gas field was discovered offshore every month; the wealth creation for the UK was gigantic. I got to see so much geology and rocks - my true passion. I moved to China in late 1983; not today’s China, this was over 40 years ago, a country closed for decades and embarking on an open-door policy, in part to bring both investment and technology. I became very interested in energy trends, energy politics, and new geography created by changing politics leading to opportunities for ene...

Mastering the Subsurface: Insights from a Geothermal Reservoir Engineer

Geothermal energy is often called the “quiet backbone” of the clean energy transition. To understand the science, challenges, and innovations driving this sector, we spoke with a seasoned geothermal reservoir engineer with experience spanning the Andes, Nevada, Utah, and volcanic fields worldwide. Here’s what they shared. By:  Robert Buluma 1. What sparked your passion for geothermal reservoir engineering, and did you ever imagine yourself working in some of the world’s most challenging geothermal fields? My passion was sparked during my early career in the petroleum industry, specifically in reservoirs. I was fascinated by the subsurface—how fluids move, how heat and pressure interact but it wasn’t until I worked on projects in Peru that I realized geothermal offered the chance to apply my skills to clean energy. I never imagined I would later work on Enhanced Geothermal Systems (EGS) projects in Nevada and Utah or Andean volcanic fields, where the geology is as unforgiving as it ...
