Oil falls further under $50 on Asia demand concern

By Ahmad Ghaddar LONDON (Reuters) - Oil fell on Monday over signs that U.S. shale drillers have adapted to lower prices and on renewed indications of economic weakness in Asia where refiners are already trimming crude runs. Brent crude was trading at $46.26 per barrel at 1042 London time, down 50 cents from its last settlement. U.S. West Texas Intermediate (WTI) crude was down 57 cents at $44.84 a barrel on the futures market.
