Utah FORGE: Phase 3A Year 1 Annual Report for 2020

공공데이터포털

This is the Utah FORGE annual report for Phase 3A year 1, which was completed on December 28th, 2020. This report includes site infrastructure, site operations, seismic monitoring, a conceptual geological model, outreach, and communications for the Utah FORGE project during Phase 3A in 2020. Utah FORGE projects showcase the role of geothermal energy and Enhanced Geothermal Systems (EGS) as a renewable source of power for the United States. The geoscientific investigations done in the Utah FORGE projects demonstrate the surrounding region holds significant potential for future EGS development.

Utah FORGE: Source Imaging DAS-Based Seismic Event Catalog - April 2024 Stimulation

공공데이터포털

This catalog contains microseismic event locations recorded during the April 2024 stimulation at the Utah FORGE site. Events were detected and located using a DAS-specific source imaging workflow that avoids conventional phase picking. Instead, STA/LTA-transformed DAS and downhole geophone traces were back-propagated through a calibrated 1D velocity model to generate a coherency field across a 3D subsurface grid. Events were identified at locations where P- and S-wave back-projections constructively aligned, and associated uncertainties were estimated from the spatial coherency distribution.

Utah FORGE: Geothermal Resource Assessment Report 2024

공공데이터포털

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.
