Oil prices drop on returning Libya, Nigeria supplies

By Mark Tay SINGAPORE (Reuters) - Oil prices fell on Friday on worries that U.S. rig counts would continue to rise and that returning Libyan and Nigerian exports would stoke a global supply glut. U.S. West Texas Intermediate futures were down 24 cents, or 0.6 percent, at $43.67 a barrel. Returning supply from Libya and Nigeria will hamper a rebalancing of the global crude market, weighing on sentiment, traders said.
