MOSCOW/DUBAI/LONDON—Some members of the OPEC+ group of oil-producing nations would need to slash output by an extra 2.31 million barrels per day (MMbbl/d) to make up for their recent oversupply, an internal OPEC+ report seen by Reuters shows.

The surplus seen between May and July ought to be compensated for in August and September, the report said.

OPEC+—which includes members of OPEC and other producers including Russia—stepped up their joint output cuts to a record 9.7 MMbbl/d in May before tapering them to 7.7 MMbbl/d this month.

In April the impact of the new coronavirus on air and road travel and other areas of the global economy sent benchmark oil prices below $16 a barrel.

The ongoing spread of the virus is now threatening oil demand recovery forecasts.

August-September

The internal report seen by Reuters did not say how the additional cuts would be distributed over August and September. But if the 2.31 MMbbl/d figure is adopted and spread equally over the two months, it would take OPEC+ oil cuts to about 8.85 MMbbl/d.

The report shows OPEC+ expects oil demand in 2020 to fall by 9.1 MMbbl/d, 100,000 bbl/d more than in its previous forecast, before rising by 7 MMbbl/d in 2021.

However, OPEC+ also see an alternative scenario in which a stronger and more-prolonged second wave of infections hits Europe, the United States, India and China in the second half of the year.

Under this scenario, demand is forecast to fall by 11.2 MMbbl/d in 2020, sending OECD commercial oil inventories in the fourth quarter to 233 MMbbl above the latest five-year average, the report showed.

Stocks would stand at 250 MMbbl above the latest five-year average in 2021.

Compliance

Data show that among OPEC members, Iraq and Nigeria were the least compliant and even the United Arab Emirates, which made additional voluntary cuts in June, overproduced by around 50,000 bbl/d over the May-July period.

Among non-OPEC participants, Russia and Kazakhstan overproduced by 280,000 bbl/d and 190,000 bbl/d, respectively.
