− | Basin paleogeographic maps are useful prospecting tools. They help us locate and predict the occurrence of [[The seven critical elements of hydrocarbon accumulation#Reservoir rock|reservoir]], [[The seven critical elements of hydrocarbon accumulation#Seal|seal]], or [[Source rock|source]] [[lithofacies]] by establishing the location of major geographic features, such as [[Lithofacies and environmental analysis of clastic depositional systems#Deltas|deltas]], [[Lithofacies and environmental analysis of clastic depositional systems#Shoreline deposits|shorelines]], [[Reef|barrier reefs]], and [[slope break]]s. Once an isochronous surface or coeval interval is identified, paleogeography can be reconstructed by integrating maps of age-equivalent lithofacies, [[Seismic facies mapping|seismic facies]], [[Biofacies and changing sea level|biofacies]], and thickness of reservoir-quality rocks. | + | Basin paleogeographic maps are useful prospecting tools.
