Oil prices ease on doubts OPEC-led cut will end glut

By Julia Payne LONDON (Reuters) - Oil prices edged lower on Wednesday on investors' doubts that OPEC would agree a large enough production cut to significantly reduce the global surplus when it meets next week. Reuters commodities analyst Wang Tao said Brent could rise to $49.85 per barrel, a level marked by several technical resistance factors. U.S. West Texas Intermediate (WTI) crude oil futures fell 12 cents to $47.91 a barrel after rising to $48.30 earlier on Wednesday.
