Based off the reported high flowrates, we estimate an equivalent porous medium transmissivity at Tungsten Mountain using doublets spaced 707 m apart of 10 -9 m 3 (~10 6 mD-m). We also assume a geologic temperature gradient of 127 °C/km and 1 km deep wells because this results in a reservoir temperature of 142°C. Lastly, we assume that each of the four injection wells and four production wells has a diameter of 31 cm (12 1/4") and a mass flowrate of 250 kg/s. We also include a GETEM scenario in which the flowrate is 110 kg/s per well, because that is the default mass flowrate in GETEM.
