The massive scale of Saudi Arabia’s oil reserves is being reflected by the world’s key producers. Saudi Aramco has grown dramatically over the past decade, upping its BOE (barrels of oil + natural gas equivalents) produced per day from 9.9 million in 2003 to 12.7 million in 2013.
According to Forbes, this impressive growth can be primarily attributed to big expansions like Khurais and Manifa with each contributing over 1 million more barrels per day. Gazprom comes second with 8.1 million BOE per day, a decline on 2003.
However, this decline in Russian oil production has been reversed by Rosneft, who are strongly backed by the Russian government and manage to churn out 4.6 million barrels per day. The National Iranian Oil Company rounds off the top three, producing 6.1 million BOE per day. This an improvement on 2003 when that number was 4.9 million.
