Oil ends up, OPEC cut commitments assuage lingering doubts

By Ethan Lou NEW YORK (Reuters) - Oil settled higher on Thursday, as commitments from Gulf OPEC members to cut production assuaged some lingering doubts in the market about cooperation from other producers. U.S. West Texas Intermediate crude gained 54 cents, or 1.1 percent, to $49.72. "Another day, another market being pushed and prodded around by OPEC rhetoric," said Matt Smith, director of commodity research at energy data provider ClipperData.
