This extended abstract describes a study explaining and demonstrating a method to identify spatial and temporal changes in fault stability from a combined assessment of InSAR and micro-seismic monitoring data. The method uses reservoir deformation inferred from InSAR data to stochastically model a micro-seismic catalogue which is compared to the measured catalogue. Discrepancies and variations in space and time between the modeled and measured catalogue are addressed by variations in stochastic parameters that are related to fault proximity, fault activation and reservoir strain. Knowledge on the transient behavior of these parameters aid in highlighting high risk zones and planning for future reservoir development options.
