Majnoon oil field is a super-giant oil field located 60 km (37 mi) from Basra, Basra Governorate in southern Iraq.[1] Majnoon is one of the richest oil fields in the world with an estimated 38 billion barrels of oil in place. The field was named Majnoon which means crazy in Arabic in reference to excessive amount of oil in a dense area.[2]


The field was discovered by Braspetro, a Brazilian company in 1975, under the leadership of Bolivar Montenegro Guerra in a shallow Upper Cretaceous formation.[2] Development came to a halt in 1980 during the engineering phase of the project, due to Iran–Iraq War, particularly Operation Kheibar. At the time, Braspetro had finished drilling of 20 wells and pressed 14 drilling rigs into service. In the course of the war, Iran occupied and sabotaged the area. After the war, Southern Oil Company of Iraq restarted the production. In 1990's, Total S.A. of France negotiated a development contract with Saddam Hussein but was unable to sign the deal due to United Nations sanctions imposed on Iraq. The deal was eventually annulled by Hussein in 2002. Due to 2003 Iraq War, production was reduced to 46,000 barrels per day (7,300 m3/d).[2] In 2007, Total and Chevron signed an agreement with Iraqi government to explore Majnoon field.[3]

On December 11, 2009, the Iraqi government awarded a license to a joint venture from Royal Dutch Shell and Petronas to take over operations at Majnoon Oilfield, and triple production from the estimated reserve of nearly 12.6 billion barrels (2.00×109 m3) at a fee rate of $1.39/barrel.[4][5] The consortium was awarded the contract out of 44 international companies, participating in the auction, with China National Petroleum Corporation (CNPC), ExxonMobil, Sinochem Corporation, Total specifically bidding on Majnoon field.[6] The finalist alliance of CNPC and Total offering $1.75/barrel lost the bid.[3] The deal intends a 20-year service and development of the field.[7][8] The contract was approved by Council of Ministers of Iraq on January 5, 2010.[9]

Shell agreed at the end of 2017 to exit the venture and hand over its operation to Basra Oil Company (BOC) by the end of June 2018. Shell was the operator and holder of 45 percent at Majnoon, with Malaysia’s Petronas owning 30 percent, and Iraq’s Missan Oil Company holding the remaining 25 percent. In June 2018 officials from Shell and Basra Oil Company met to mark the handing over of the operations of the field.

In April 2018, Anton Oilfield Services and Petrofac signed a two-year deal with Iraq’s oil ministry to operate the Majnoon field on behalf of Basra Oil Company.[10]

In May 2018, KBR, Inc. announced that it has been awarded a contract by Basra Oil Company (BOC) for the development of the Majnoon Oil Field in Basra, Iraq.[11]


The operator Shell holds 45% stake in all licences, while Petronas and Iraqi Ministry of Oil hold 30% and 25% of interest.[12] According to company officials, the project will require tens of billions of dollars over the 20-year period.[13]


Majnoon's first pay zone consists of Upper Cretaceous which proved 4,000 barrels (640 m3) of oil per day in 1976. Mishrif carbonates, Nahr Umr sands (Middle Cretaceous) and Shuaiba carbonates and Zubair sands (Lower Cretaceous) form the pay zones.[2]


According to the deal, the consortium will increase production to a peak 1.8 million barrels (290,000 m3) of oil per day within seven-year period.[1] Majnoon was the first Iraqi field out of 10 major ones offered to international companies for development.[2] The contract with Shell and Petronas includes drilling over 40 production wells, construction of three gas separation stations and two crude oil processing refineries with overall capacity of 100,000 barrels per day (16,000 m3/d).[1][2] The official start date was March 1, 2010.[14] In the Phase I of the project, the consortium intends to increase the production from 45,000 to 175,000 barrels per day (27,800 m3/d) within two-year period.[1][15]

The production at Majnoon will move Iraq from the current 11th place to the 3rd among oil producing nations after Saudi Arabia and Iran.[14] The country sits on 150 billion of oil and currently produces 2.5 million barrels per day (400,000 m3/d). Iraq expects to top the oil production to 7 million barrels per day (1,100,000 m3/d) within six years, thus competing with Saudi Arabia.[2]
