Zubair oil field is located in southern Iraq, approximately 20km south-west of the city of Basrah. The onshore oil field, discovered by Basrah Petroleum Company in 1949, contains 4.5 billion barrels of proven reserves.

 

The field is being redeveloped by a consortium comprising of Eni (32.81%), Oxy (23.44%), KOGAS (18.75%) and Missan Oil Company (25%). The consortium was awarded the field license in October 2009 for a period of 25 years.

 

Eni, which has the biggest share in the consortium, started operating the oil field in early 2010. The field currently produces about 200,000 barrels of oil per day. The redevelopment project is expected to increase the field’s production capacity to 1.2 million barrels of oil per day by 2016.

 

Zubair redevelopment project details

The redevelopment project primarily involves the drilling of more than 200 wells, the construction of treatment and storage facilities, and refurbishment of the existing facilities.

 

The new oil and gas processing plant will be capable of treating 80,000 barrels of crude oil per day. Six crude oil storage tanks with a capacity of 58,000m³ each will be installed at the site.

 

A 740MW gas-fired power plant will also be constructed as part of the redevelopment project. Construction of the workers’ site buildings covering a total area of 25,788m² was completed in October 2012.

The front-end engineering design (FEED) studies for the project were carried out by Enereco. The feasibility study for the off-site activities was carried out by Compagnia Technici Ingegneri.

 

The engineering, procurement and construction (EPC) activities, including the pre-commissioning of the gas and oil separation plant (GOSP) with a capacity of 200,000 barrels per day, was awarded to Samsung Engineering in March 2014. The contract, awarded on a lump-sum turnkey basis, is worth $840m.

 

A KRW 220bn ($208m) contract for the construction of the oil and gas processing plant was awarded to STX Heavy Industries, while the EPC contract for the installation of new flow tanks was awarded to Rosco. The EPC contractor for the gas-fired power plant is Alstom, which will supply four GT13E2 gas turbines under the €400m worth contract.

 

The EPC contractor for the early production facility (EPF) is Weatherford International. The process vessels for the EPF will be supplied by Velath, while the API 610 OH2 A-Series pumps will be supplied by Amarinth. Habtoor Leighton Group (HLG) has been subcontracted by Weatherford to carry out certain engineering works and construction of civil, utility and infrastructure facilities the project.
