We numerically model microearthquakes (MEQs) and electrical/electromagnetic (EM) signals from solutions of coupled flow-geomechanics simulation. Specifically, the MEQs are calculated by geomechanics solutions such as the area, displacement, and direction of the newly created hydraulic fractures, while the EM signals can be generated by flow solutions such as pore space occupied by the injected fluid. The framework of this integrated forward simulation can be useful for joint analysis and inversion for characterizing the hydraulically fractured reservoirs and for detecting the propagation of hydraulic fractures, integrating the in situ data such as production/injection data, induced seismicity, and the EM data.
