Crude oil futures fell for the secont time in five sessions, hurt by a stronger U.S. dollar and another build in oil inventories, according to rttnews.
WTI light sweet crude oil fell 61 cents, or 1.4%, to settle at $44.66 a barrel on the New York Mercantile Exchange.
That's after a report showed OPEC's oil production rose to record highs in October.
The International Energy Agency said OPEC crude output rose by a 230,000 barrels a day to a record high of 33.83 million barrels a day in October.
The IEA said OPEC faces a significant challenge in curbing production to meet levels discussed at a recent meeting in Algiers.
"We can't predict the outcome of the November 30 meeting, but we can see the scale of the task ahead," said the IEA.
