Oil producers said Sunday that their landmark December deal to slash output by almost two million barrels per day was on track, as they met to review progress.
"Compliance is great, it`s been really fantastic," Khaled al-Falih, energy minister of oil behemoth Saudi Arabia, was quoted by Bloomberg as saying.
"Based on everything I know, I think it`s been one of the best agreements we`ve had for a long time," he said in Vienna.
He added that he hoped all countries would reach full compliance next month and forecast that brimming global oil stocks would return to normal levels by mid-year.
The December 10 accord, valid from January 1 for six months, obliges 24 countries inside and outside the
OPEC group to cut production by 1.8 million bpd between them.
The aim is to reduce a global glut that has depressed oil prices and blown a huge hole in the public finances of producer nations, despite being good news for consumers.
Markets initially welcomed the accord in December, sending oil prices up to an 18-month high of $58.
But they have since slipped back on concerns countries may not stick to their commitments -- as has happened under previous deals.
Falih he said however that producers have already removed 1.5 million bpd from the market, more than 80 percent of their collective target.
And global oil stocks Alexander Novak said Moscow was "ahead of schedule" and "doing our best to maximise participation" in the agreement, Bloomberg reported.
Russia has reduced production by an average of 100,000 bpd, a milestone it had not expected to reach until next month, Novak said.
Russia has said it would make a daily reduction of 300,000 barrels by April or May.
Saudi Arabia has already exceeded its target with an output reduction of more than 500,000 bpd, Falih said, while Algeria and Kuwait have also cut to levels beyond their targets, Bloomberg reported.
Other OPEC members such as Iraq and Venezuela have not yet reached their quotas but say they are more than halfway there.
OPEC`s total production fell by 221,000 bpd to 33.1 million bpd in December, according to secondary sources data in OPEC`s monthly report published last week.
Under the deal it agreed to reduce output to 32.5 million bpd. However that includes about 740,000 bpd from former member Indonesia, Bloomberg said.
- Extension `unlikely` -
The deal is renewable for an additional six months but Falih said earlier this month that an extension was "unlikely".
To track compliance, the producers have created a Joint OPEC-Non-OPEC Ministerial Monitoring Committee (JMMC) which met Sunday for the first time.
A statement published afterwards said that the JMMC "expressed its satisfaction regarding the strong level of commitment to the agreed framework".
The gathering focused mostly on how compliance will be assessed, agreeing to produce regular reports and updates and share analyses among producers.
"We started to trust each other better, which is just as important as the market re-balancing,” Novak said.
"One year ago not many believed in the success of this initiative."
