Utah FORGE: Geothermal Resource Assessment Report
This report provides a first-order assessment of the producible energy from the Utah FORGE EGS reservoir, based on stimulation and circulation testing in 2024. The assessment is based on a stored heat calculation for a cylindrical volume of stimulated hot dry rock enveloping the deviated legs of wells 16A(78)-32 and 16B(78)-32, and conservative estimates for recoverable energy. It also shows the potential for increased power production with deepening of the reservoir. The results are compared with the power produced during the 27-day circulation test in August-September 2024.
