Oil prices fell in Asian trade on Monday on a strong dollar and signs that global crude supply is holding up even as volumes hit by unplanned outages rise to at least five-year highs.
In a further indication of abundant supply, the number of rigs operated by U.S. drillers was steady last week for the first time this year.
Brent futures had dropped 57 cents to $48.15 a barrel by 0641 GMT, after ending the previous session 9 cents down.
