Evaluation of flow paths during stimulation in an EGS reservoir using microseismic information

•We propose a method to evaluate flow pathways in geothermal reservoirs.•Our method utilizes microseismic and in-situ stress information.•The flow pathway model is optimized to fit the inferred pore pressure distribution.•Our method could discover fluid flow features in the Basel EGS field. Evaluati...
