NEW YORK (Reuters) - Oil prices hit a record high $117 a barrel Friday as jitters over Nigerian oil supplies outweighed a rally in the dollar and fears of an economic slowdown in giant energy consumer China.
U.S. light crude settled up $1.83 at $116.96 a barrel, before hitting a record $117. London Brent crude gained $1.49 to $113.92.
Oil prices have more than quadrupled since 2002 as supply struggles to keep up with booming demand, especially in China and other emerging economies
