Oil futures settled lower on Thursday, with U.S. prices down for the first time in six sessions, a day after the front-month contract settled at the highest since October 2014. Prices got a boost Wednesday as the Energy Information Administration reported a weekly decline in U.S. crude inventories — the first in four weeks. On its first full trading day as a front-month contract, West Texas Intermediate crude for December delivery CLZ21, 0.51% fell 92 cents, or 1.1%, to settle at $82.50 a barrel on the New York Mercantile Exchange.
