− | Basin paleogeographic maps are useful prospecting tools. They help us locate and predict the occurrence of reservoir, seal, or source lithofacies by establishing the location of major geographic features, such as deltas, shorelines, barrier reefs, and slope breaks. Once an isochronous surface or coeval interval is identified, paleogeography can be reconstructed by integrating maps of age-equivalent lithofacies, seismic facies, biofacies, and thickness of reservoir-quality rocks. | + | Basin paleogeographic maps are useful prospecting tools.
