Abstract Eolianites are wind-driven supratidal and continental accumulations of carbonate dominated sand, lithified by carbonate cement. These bodies can reach huge spatial extents. Being formed by the landward continental accumulation of shallow-marine particles, they can be easily misinterpreted as subtidal high-energy deposits. Due to their granular composition, eolianites of important size may represent valuable hydrocarbon reservoirs. This study treats issues concerning their preservation potential, their recognition, their sequence-stratigraphic response and reservoir potentia. Their important reservoir potential is enforced by the reinterpretation as an eolianite of the main reservoir layer of present-day's largest gas field. The recognition of these neglected deposits among the stratigraphic record may open the door to better understanding and knowledge of past littoral and shallow marine carbonate system and carbonate reservoirs.
