EGS Hot Dry Rock Energy Resource at Utah FORGE – A Geoscientific Perspective

Oct 16, 2025 | Research News, Webinars

The heat beneath our feet flows through the earth in a complex pattern. Utah FORGE is situated in a heat reservoir that has been studied since the 1970s. In this webinar, Dr. Stuart Simmons delves into the unique geologic and geothermal resources found at Utah FORGE and the surrounding area.

The geoscientific attributes which control the size and extent of the geothermal resources around Utah FORGE include a comparison of differences and similarities between conventional and EGS reservoirs, as well as a simple method for energy resource assessment based on the Utah FORGE reservoir, and a conceptual understanding of the geothermal system that is responsible for the resources occurring in the Milford valley.
