Oil prices stable as U.S. output gains offset OPEC-led cuts

By Henning Gloystein SINGAPORE (Reuters) - Oil prices were stable on Friday, with rising crude output from the United States offsetting efforts by OPEC and other producers to prop up the market by cutting supplies. Brent crude futures, the international benchmark for oil prices, were trading at $56.21 per barrel at 0231 GMT, virtually unchanged from their last close. U.S. West Texas Intermediate (WTI) crude futures were at $53.84 a barrel, up 6 cents.
