Oil prices were mixed on Friday after big gains a day earlier when the International Energy Agency (IEA) predicted crude stockpiles would start to shrink in second-half 2020 after surging while the coronavirus pandemic slashed fuel demand.

Brent crude was up 1 cent at USD 31.13 a barrel by 0115 GMT, after rising nearly 7 percent on Thursday. The global benchmark is roughly flat on the week after rising for the previous two weeks.

Giving up earlier gains, West Texas Intermediate (WTI) oil was down 13 cents, or 0.5 percent, at USD 27.43 a barrel, having jumped 9 percent in the previous session. WTI is still heading for a third weekly gain, up more than 10 percent.

Prices have been lifted by more signs that oil output is falling among OPEC and other major producers, a grouping known as OPEC+. But the market mood remains cautious, with the coronavirus pandemic far from over and new clusters emerging in countries where lockdowns have been eased.

There remains the "risk of renewed outbreaks of COVID-19 ... and questionmarks over how far OPEC+ production cuts will be implemented," ANZ said in a note.

Still, as demand increases with the easing of lockdowns to get economies going again, the IEA said it expects crude inventories to fall by about 5.5 million bpd in the second half of this year.

US crude inventories fell for the first time in 15 weeks, the Energy Information Administration said on Wednesday, dropping by 745,000 barrels to 531.5 million barrels in the week to May 8. Analysts had expected another increase.

Output cuts will boost the trend towards lower inventories.

OPEC+ had already agreed to cut production by nearly 10 million bpd, a record amount, and Saudi Arabia extended its planned reductions for June, pledging earlier this week to slashing production by nearly 5 million barrels per day.

Saudi Aramco, the world's largest oil exporter, reduced the volume of crude it will supply to at least three buyers in Asia by as much as 30 percent for June, three sources with knowledge of the matter told Reuters on Thursday.

OPEC+ now wants to extend overall production cuts beyond May and June when the group next meets, sources told Reuters earlier this week.
