This is the final technical report documenting laboratory experiments and modeling conducted to characterize the thermo-poromechanical behavior of fractured crystalline rocks for application to Utah FORGE. The report includes measurements of poroelastic and thermo-poroelastic properties, permeability evolution, hydraulic fracture closure and reopening behavior, diagnostic fracture interpretation test (DFIT) experiments, and modeling results relevant to stress determination, fracture mechanics, and enhanced geothermal systems.
