This contains a final technical report and closeout presentation recording summarizing the results from Utah FORGE Project 5-2557 on the role of fluid pressure and temperature in fracture mechanics and coupled thermo-hydro-mechanical-chemical (THMC) processes relevant to enhanced geothermal systems. The report documents laboratory experiments, theoretical developments, and numerical simulations validated with Utah FORGE field circulation tests that quantify fracture slip, permeability evolution, and seismic/aseismic behavior. Deliverables include curated experimental datasets, validated open source tools (MOOSE FARM, extended friction theory, and AI based joint inversion), and supporting publications archived in the Geothermal Data Repository to enable reproducible research and geothermal reservoir optimization.
