 Crude oil output from the Organization of Petroleum Exporting Countries (OPEC) climbed by 90,000 barrels per day (b/d) in August to 31.54 million b/d as increases from Angola, Iraq, Nigeria and the United Arab Emirates (UAE) outstripped decreases from Algeria and Iran, a Platts survey of OPEC and oil industry officials and analysts showed Tuesday. This follows July production of 31.45 million b/d and leaves OPEC overproducing its 30 million b/d ceiling by 1.54 million b/d.
