This submission contains the final technical report and closeout presentation for Utah FORGE Project 5-2419, which investigates the coupled evolution of permeability and induced seismicity in enhanced geothermal systems using laboratory experiments, field observations, and nonlinear acoustic imaging. The work integrates fault reactivation experiments on Utah FORGE reservoir rocks, high-resolution microearthquake data from Utah FORGE and EGS Collab stimulations, and physics informed modeling and machine learning to establish quantitative relationships between seismic moment, stress state, and permeability creation. Results provide diagnostic tools to estimate permeability evolution and seismic hazard from microseismic observations, informing safer and more effective stimulation strategies for EGS development.
