Oil producers including Gulf OPEC members support holding talks next month on a deal to keep production at current levels, even if Iran declines to participate, OPEC sources said on Wednesday.
A meeting would increase the likelihood of the first global supply deal in 15 years.
U.S. crude was up 65 cents at 39.11 dollars a barrel at 0452 GMT, having earlier risen as high as 39.38 dollars.
Brent crude rose 38 cents to 40.71 dollars.
“A smaller than expected gain in inventories in the U.S. also supported prices,” ANZ said in a morning note.
Crude inventories increased 1.3 million barrels in the week to March 11 to 523.2 million, a much smaller build than the 3.4 million-barrel increase expected by analysts.
The market is also rallying after a less hawkish U.S. monetary outlook, as the U.S. Federal Reserve held interest rates steady and indicated two rate hikes this year instead of the four expected.
Qatari oil minister Mohammed Bin Saleh Al-Sada said producers from within and outside the Organization of the Petroleum Exporting Countries (OPEC) will meet in Doha on April 17 to discuss plans for a freeze in output.
The initiative was supported by around 15 OPEC and non-OPEC producers, accounting for about 73 per cent of global oil production, the minister said.
Since the freeze was first proposed last month, prices have recovered about 50 per cent from decade-low levels.(Reuters/NAN)
