|Burgan Field (Al Burqan)|
Much of western and southern Kuwait is home to some of the largest oil fields in the world. The dark patch of land in southern Kuwait is where the Al Burqan oil field is located.

The onshore supergiant Burgan field is an oil field situated in the desert of southeastern Kuwait. Burgan field can also refer to the Greater Burgan—a group of three closely spaced fields, which includes Burgan field itself as well as the much smaller Magwa and Ahmadi fields. Greater Burgan is the world's largest sandstone oil field.
Discovery and geology
A natural surface oil seep above the Burgan field was known to mankind since neolithic time, bituminous material from a reed boat discovered in As-Sabiyah/North Kuwait and dated 5000 BC have been traced back to this seep.(Connan et al, 2005) The subsurface reservoirs of the Burgan oil field were discovered in February, 1938. The US and UK-owned Kuwait Oil Company began commercial oil production at Burgan in 1946.
The Greater Burgan, a wider area around Burgan, is the world largest sandstone (clastic) oil field with the total surface area of about 1000 km2. It includes three producing subfields: Burgan itself (500 km2), Magwa (180 km2) and Ahmadi (140 km2). The Burgan field's structure is an anticlinal dome having an elliptical shape and transected by numerous radial faults. Both Magwa and Ahmadi are located on smaller, subsidiary domes north of Burgan 
The oil is contained in the four main horizons of Cretaceous age: Wara (sandstone), Mauddud (limestone), Burgan Third Sand (3S) and Burgan Fourth Sand (4S). Burgan Third Sand is in turn subdivided into Third Sand Upper (3SU), Third Sand Middle (3SM) and Third Sand Lower (3SL). Historically the production has come mainly from the 3SM unit. By 1992 the second and third sand units had been swept by water.
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 1,700,000 barrels per day (270,000 m3/d) in 2005. This was lower than it had been in the past—it reached as high as 2,400,000 barrels per day (380,000 m3/d) 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 1,640,000 bbl/d (261,000 m3/d) in 2020 and 1,530,000 bbl/d (243,000 m3/d) in 2030. In 2005, the Kuwait Oil Co. estimated a remaining life of 30 to 40 years for Burgan, at a production rate of about 1.7 million barrels a day. 
The possibilities of deeper plays below the known Burgan oil & gas resource appear to be under-explored. 
In 1991, retreating Iraqi soldiers set Burgan Field on fire. Smoke plumes from the Greater Burgan oil field extended 50 kilometers in width on any given day, and 2.5 km thick. From satellite observations the plume appeared like a black snake in the desert that extended parallel to the Persian Gulf (EOS Project NASA Goddard Space Flight Center). The Red Adair Service and Marine Company extinguished 117 of the burning well fires, while the Canadian company Safety Boss set the pace with 180 wells extinguished. Declassified 1991 CIA documents claimed that despite the destruction there was no significant depletion of the oil reserves and drop in production capacity at Burgan field. Three gathering stations were, however, too badly damaged to repair.
