The Kuwait Supreme Petroleum Council may decide by the end of September whether to build a fourth oil refinery to meet domestic fuel demand and for export, Reuters has reported. The refinery, to be located at Al Zour, will mainly process heavy crude oil the country is now developing, as well as Kuwait's export blend. The refinery could start by 2015 as the main design and engineering work for the project is done, Bakhit Al-Rashidi, deputy managing director of planning at Kuwait National Petroleum, said in April.
