Saudi Arabia and other OPEC members were seeking to win support from Russia on March 4 to join them in new additional oil output cuts to prop up prices which have tumbled by a fifth this year because of the coronavirus outbreak.

A technical panel of several representatives from OPEC states, Russia and other producers recommended on March 3 cutting output by between 0.6-1 million barrels per day (bbl/d) during the second quarter only.

It also recommended that existing cuts of 2.1 million bbl/d by the group known as OPEC+, which meets in Vienna this week, be extended until the end of 2020.

Russia has so far signaled it might be willing to agree to extending existing cuts, which expire in March, but might find it difficult to sign up to deeper cuts.

"OPEC hopes for a cut bigger than 1 million but the challenge is still Russia," an OPEC source said. Two other sources confirmed talks were now focusing on additional cuts in excess of 1 million bbl/d.

Saudi Energy Minister Prince Abdulaziz bin Salman met his Russian counterpart Alexander Novak on Wednesday. The Joint Ministerial Monitoring Committee (JMMC), comprising a handful of OPEC and non-OPEC ministers, will convene in Vienna on Wednesday.

The Saudi and Russian ministers have made no public statements so far since arriving to Vienna.

'Downward Revisions'

Sources told Reuters this month OPEC could agree deeper cuts even without Russia. One source said March 4 that Russia would seek to keep its participation in any new cut to a minimum.

"Cuts will need to at least be towards the top end of the range, as we see further downward revisions in demand growth as Covid-19 spreads. There is more evidence of the spread of the virus having an impact on demand outside of China," Warren Patterson from ING said in a note.

Existing cuts have not been enough to counter the impact of the new coronavirus, Covid-19, on China, the world's biggest oil importer, and on the global economy. Factories have been disrupted, fewer people are traveling and other business has slowed, driving down oil demand.

Benchmark Brent oil prices were around $52 a barrel on March 4, a level at which many OPEC states will struggle to balance their budgets, although Russian President Vladimir Putin has said the current price was acceptable.

With global efforts to prevent the virus spreading, OPEC has said the number of delegates at its meetings in Vienna this week will be kept to a minimum and journalists have been barred from entering the OPEC headquarters.

Iranian Oil Minister Bijan Zanganeh arrived for the talks in Vienna as Iran's government said the virus had now affected most of the provinces in the Islamic Republic.

The March 4 JMMC meeting is part of the process of drawing up recommendations for the wider meeting of ministers from OPEC on March 5 and a meeting of OPEC+ ministers on March 6.
