Tide-dominated or tide-influenced coastal marine deposits form some of the most complicated and largest hydrocarbon fields in the world (Wood, 2004 and references cited therein). Good outcrop analogs can provide significant insight to geologists for recognizing tidal influence in core and interpreting petrophysical log data, thus reducing uncertainty and risk when developing depositional models and planning for field development. Despite the observation that 8 of the 12 largest deltas in the modern world are either tide dominated or strongly tidally influenced (Middleton, 1991), many geologists fail to recognize tidal influence in the rock record, perhaps, in part, because of the influence of preexisting paradigms. This seems to be particularly so for many geologists prospecting for hydrocarbons within Pennsylvanian sediments in the Arkoma and Anadarko Basin of the southcentral United States.
