| Abstract | Many numerical reservoir simulators have been used in the geothermal industry, with their valid performance confirmed using publicly available s. These simulators will have nearly identical performance for single-porosity models and parameters are easily compared between different simulators. When implementing dual-porosity formulations, the choice between MINC, dual-porosity, and dual-permeability leads a divergence in the comparability of these parameters. Through history matching and analog studies, the modeling community has converged on a range of values for several parameters that improve forecasting with realistic predictions of thermal breakthrough. This paper compares three simulators and their available dual-porosity parameters to identify a conversion approach between the softwares. A field history example from Brady's Hot Springs is presented with the corresponding applicable parameters for several dual-porosity approaches. |
