 "Crude oil prices dip due to record rise in US output, higher OPEC supplies")
Brent crude oil futures dipped for a second session on Monday, with prices coming under pressure from record U.S. output and expectations of higher OPEC supplies.
Global benchmark Brent was down 12 cents, or 0.16 percent, at $76.67 a barrel by 0159 GMT.
"Crude oil remained under pressure as the market remained focused on the discussion between OPEC members about whether they should increase production later this year," ANZ said in a note.
"In the U.S., the data also presented a gloomy picture. Crude oil production rose to another record, while drilling activity picked up again."
But U.S. West Texas Intermediate (WTI) crude futures gained 6 cents, or 0.09 percent, to $65.87 a barrel. Last week, the market lost around 3 percent, adding to a near 5-percent decline from a week before.
"We are going into summer, the high demand season, and I think we are going to see a fall in U.S. crude oil inventories, but shale oil output is growing. Which one is going to win is the issue," said Tony Nunan, oil risk manager at Mitsubishi Corp in Tokyo.
