LONDON, Nov. 12, 2012 /PRNewswire/ -- Crude oil output from the Organization of Petroleum Exporting Countries (OPEC) edged up by 20,000 barrels per day (b/d) to 31.17 million b/d in October, a Platts survey of OPEC and oil industry officials and analysts showed November 9. This follows September production of 31.15 million b/d and leaves OPEC exceeding its 30 million b/d output ceiling that was agreed to last December and extended in June, by more than one million b/d. A drop of 50,000 b/d in Nigeria was more than offset by small increases in Angola, Iraq and Libya, the survey found. "Numbers like these could mean that the OPEC meeting next month is the Goldilocks meeting, not too high, not too low," says John Kingston, director of news, Platts, a leading global energy, petrochemicals and metals information provider. "Prices are holding near $100 per barrel for Brent crude oil, which is enough to keep most members happy, but aren't too high as to threaten the global economy." The one thing that could significantly change that scenario would be a stalemate in the U.S. to avoid the so-called 'fiscal cliff,' explained Kingston, which sources say could hammer the prices of all financial assets, including oil. "Thus, it's hard to see anything that could send prices significantly higher, but there certainly are some extra-market scenarios that could send them lower," Kingston said. Iranian volumes, which have dropped steadily in recent months as sanctions imposed by the U.S. and E.U. took their toll on exports, were stable at 2.72 million b/d in October. OPEC's four Gulf Arab producers maintained volumes at levels similar to those of September, the survey found, while a further increase in exports took Iraqi output to 3.21 million b/d.
