1. A method of modeling a geological body with a lateral extent spanning a plurality of fault blocks in a contemporary formation, wherein a fault block of the plurality of fault blocks comprises a plurality of block units, the method comprising: using a computer performing the steps of: transforming a block unit of the plurality of block units from contemporary space to paleo-space to generate a transformed block unit; constructing the geological body using data acquired from the contemporary formation in a depositional paleo-space model having the transformed block unit, wherein the geological body intersects at least the transformed block unit; making a copy of the geological body; transforming the copy from paleo-space to contemporary space based on a deformation model of the contemporary formation, wherein transforming the copy generates a portion of a model of the geological body in contemporary space; trimming the portion of the model to fit the block unit of the contemporary formation; and storing the portion of the model.
