Abstract: A technique includes inverting seismic data acquired for a subsurface region to determine dynamic elastic properties and converting the dynamic elastic properties to static elastic properties and rock strength properties. The technique includes generating a three-dimensional mechanical earth model for the subsurface region, where the model includes the dynamic elastic properties, the static elastic properties, the rock strength properties and a subsurface stress field. The technique can include a calibration step that matches seismic data observations to predictions from the geomechanical model.
