Looking closer at the Burgan field the formation is made up of several radial faults that help trap the petroleum content in the formation. These faults and the Burgan graben are what cause the compartmentalization of the reservoir. This compartmentalization makes for great petroleum play and holds it in place well over a long period of time. The source rock that caps this formation is known as the Mauddad Limestone.( the above diagrams help give you a better visual on the formation as a whole) 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. Attempts to find deeper oil plays have been made. In 1951 discovery of the Berriasian-age Minagish Oolite Limestone in Burgan was made along with the Jurassic carbonate at Magwa and both proved to be holding oil. However, production did not make way from these subsurface discoveries. Oil reserves, production capacity and estimated lifetime "The reserves and production data for Burgan are shrouded in a cloud of secrecy, uncertainty, and controversy." Burgan's total potential production of recoverable oil has been estimated as between 66 and 75 billion barrels, plus perhaps 70 trillion cubic ft. of natural gas. Bloomberg estimated remaining reserves of 55 billion barrels as of 2005. Cumulative production through 1996 was estimated by a consulting firm at around 28 billion barrels of oil. Burgan's production capacity stood at in 2005. It was the fourth most productive oilfield worldwide in 2013, per Oil Patch Asia. This was lower than it had been in the past—it reached as high as in 1972. The actual oil production from the field in 2005 was between 1,300,000 and 1,700,000 barrels per day. The International Energy Agency then predicted an output of in 2020 and in 2030. In 2005, the Kuwait
