Crude oil eased from a five-week high on Tuesday as rising U.S. shale oil production offset concerns over geopolitical tensions in the Middle East and output cuts being made to support prices.
The international benchmark for oil prices, Brent crude futures, were down 4 cents, or 0.1 percent, from its previous close at $55.94 per barrel at 0510 GMT. Earlier, Brent had climbed to its highest since March 7 at $56.16 a barrel.
