A 3D earth model, a geophysical/geologic three-dimensional (3D) model of the earth, is best described in terms of its exploration objective. This means that when its geologic target is established, the model is designed to represent the geologic environment surrounding the prospective target. The areal extent covered can range from regional (i.e., hundreds of OCS blocks) to a detailed nine blocks.

At minimum, the earth model is an accumulation of the results of multiple sciences approximating the earth's lithology. At best, through the skilled interpretation of integrating the results of these sciences, it can bring new insight through the refinement...
