The Az Zubair Field, also known as Az-Zubayr, is an oil field located in southern Iraq, west of Basrah. It is one of the largest fields in the world and was discovered in 1949. It has 4.5 billion barrels (~6.1×10 8 t) of proven reserves and currently produces 195 thousand barrels per day (31.0×10 3 m3/d) but in the next years, under the field's expansion programme, production is expected to reach a plateau level of 1.125 million barrels per day (178.9×10 3 m3/d).[1]
The development contract has been awarded to a consortium led by Eni (32.81%) with Occidental Petroleum Corporation (23.44%), Korea Gas Corporation (18.75%) and Iraq's state-run Missan Oil Company (25%).[2]
