(a) Rock material properties used in the model. Notes: Corey relative permeability values of Slr = 0.3 and Sgr = 0.05 and a specific heat of 1000 J/kg°C were assigned to all model domains. Rock density, porosity, and heat conductivity data are from Chernyak et al. [9], whereas permeability data are from Kiryukhin et al. [10], using analogous reservoirs
