A current problem in oil recovery is knowledge of the reservoir's external geometry and the effect of geologic heterogeneities on hydrocarbon flow. Geologic heterogeneities compartmentalize reservoirs into flow units, preventing efficient drainage and sweep of reservoirs.

Understanding 3-D geometry, spatial organization, genesis, and evolution of folds and faults is essential to providing a realistic conceptual model for flow studies. Wireline log-based structural models of mature giant oil fields, such as La Cira–Infantas, Colombia, do not provide clear delineation of production boundaries and compartments. In La Cira–Infantas, the characteristics and evolution of its structural style are not well understood. Published interpretations...
