Iraq's oil production has surged to its highest level in over 30 years last month. International Energy Agency in its latest report said that Iraq's oil output jumped by half a million barrels a day in February to average 3.6 million barrels a day.The country hasn't pumped that much oil since 1979, when Saddam Hussein rose to power.Shipments of oil from the country rose to 2.8 million barrels a day in February, up by 600,000 barrels a day compared with a year ago.Last month's surprise jump in oil production came as a major bottleneck at Iraq's southern export terminal Basra was finally removed.The move has surprised skeptics skeptics of the country's efforts to restore its oil industry after decades of war and neglect.Iraq holds the world's fifth-largest proven reserves. Iraq's oil minister said last December that his country would target oil production of 4.1 million barrels a day in 2014.He told that the new fields coming on stream are expected to add 500,000 barrels a day of output in the next few months.
