Oil prices fell in early trading on Monday as the chances of Middle East producers agreeing to curb overproduction appeared to fade, while U.S. output remains stubbornly high.
Front month U.S. West Texas Intermediate (WTI) crude futures were trading at $36.25 per barrel at 0143 GMT, down 1.5 percent or 54 cents from their last settlement.
International Brent futures were down 1 percent or 40 cents at $38.27 a barrel.
The falls extended a 4 percent tumble on Friday when Saudi Arabia said it would only participate in a global freeze of its output if its rival Iran also took part, something Tehran has so far dismissed.
