Energy futures prices were mixed in active trading after a projection that OPEC’s January production would fall below its quota. On the New York Mercantile Exchange, the February contract for West Texas Intermediate, the benchmark grade of U.S. crude oil, rose 31 cents to close at $18.48 a barrel after advancing 3 cents on Thursday. The contract traded as high as $18.64 during Friday’s session but retreated on profit taking, analysts said. Other crude contract months were mixed.
