Investing.com - Oil was higher early Monday on talk of supply curbs by some OPEC members.
U.S. crude was up 62 cents, or 1.48%, at $42.42 at 06:45 ET, while Brent crude added 1.38% to $44.88.
The possibility of an OPEC cap on output is unlikely as key members push ahead with efforts to increase market share.
OPEC said Monday it expects demand for oil and prices to increase in the second half of this year.
The cartel is also due to hold an informal meeting next month.
However, the short-term outlook for oil prices remains bearish, with a jump in the number of short positions in U.S. crude.
Baker Hughes figures Friday showed the number of rigs operating in the U.S. rose by 7 to 381.
That was the highest level since March and the sixth week in a row the rig count has risen.
