Oil prices edged higher on Tuesday after falling nearly 2 percent in the previous session, but growing U.S. production and expectations of higher OPEC supplies continue to weigh on sentiment.
Brent crude futures added 15 cents, or 0.2 percent, to $75.44 a barrel at 0020 GMT, after settling down 2 percent at $75.29 a barrel on Monday.
U.S. West Texas Intermediate (WTI) crude was up 28 cents, or 0.4 percent, at $65.03 a barrel. It finished the previous session 1.6 percent lower at $64.75 a barrel.
"It's all about supply, whether it's OPEC raising output or U.S. increasing production, all roads lead to higher global oil supplies, which is leaving oil traders shaking in their boots," said Stephen Innes, head of trading for Asia-Pacific at futures brokerage OANDA in Singapore.
The Organization of the Petroleum Exporting Countries (OPEC) is due to meet in Vienna on June 22 to decide whether the group and non-OPEC members including Russia will raise production to ease concerns over potential supply shortfalls from Iran and Venezuela.
Over the weekend, OPEC and non-OPEC Arab oil ministers agreed on the need for continued cooperation to balance global supply, Kuwait's state news agency KUNA reported.
