The Paleo environment of the Greater Burgan Field suggest the field began constructing in the lower and upper Burgan sand based on a fluvial system accommodated by transgressive coastline movements over time. Following the Burgan Formation, the Mauddud Limestone Formation (source Rock) began forming. The Mauddud formation is made up of shallow marine, bioclast wackestone, grainstone, and shoal surrounded by lagoonal dolomite. Lastly, the Wara formation is created by a fluvial system exposed to bio clastic dolomite known as the wara shales. These shales were formed during the falling RSL. Finishing the Wara formation the fluvial valleys are filled with tidal estuaries caused by transgressive and RSL high stand. The formation is capped off by the Ahmadi Cap rock.
