SYSTEM AND METHOD OF BUILDING COMPLEX EARTH MODELS

A method is described that includes accessing, for a geological medium: a horizon model including a plurality of horizons in the geological medium; a fault model including a plurality of faults in the geological medium; and a rock property model including one or more physical rock properties at a plurality of spatial locations on a first grid corresponding to the geological medium. The method further includes determining intersections between the horizons and the faults by correlating the horizon model with the fault model and calculating a faulted structural model for the geological medium in accordance with the intersections between the horizons and the faults. The method further includes generating an earth model for seismic forward modeling by assigning one or more physical rock properties to the faulted structural model in accordance with the rock property model.
