A transient mass balance model is developed to account for the dynamic behavior of an artificially stimulated hot dry rock (HDR) geothermal reservoir system in fractured granitic rock. Fluid mixing between fractured zones, hydrodynamic dispersion within zones, pore fluid displacement, and mineral dissolution effects are incorporated into the model. A two-zone system is sufficient to account for the major observed results from field testing of the Fenton Hill HDR system.
