One or more techniques for determining time-varying stress and strain fieldswithin asubsurface region include integrating a seismic model (110) of a reservoirwithin thesubsurface region with a geomechanical model (140) of the subsurface region.An estimateof the time-varying stress and strain fields within the subsurface regionduring production ofthe reservoir are determined, wherein the estimate is based on the integrationof the seismicmodel with the geomechanical model. The integration of the seismic model withthegeomechanical model can be used to predict the feasibility of passive seismicmonitoring fora reservoir within a subsurface region (170).
