Mastering the Subsurface: A Geothermal Reservoir Engineer's Insights on EGS, Stimulation, Digital Twins, and the Future of Clean Baseload Power
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 This interview was conducted by Robert Buluma, Founder of Alphaxioms. The responses were provided by Jerjes Porlles, Ph.D., Regional Technical & Business Development Manager – Latin America at Avasthi & Associates, Worldwide Energy Consulting. 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...
