For the month, output amounted to 100.63 million b/d, a mere 67,000 b/d over March, according to Energy Intelligence's calculations. Nearly all the gain in non-Opec-plus came from the US, where output climbed 294,000 b/d to 20.24 million b/d. In terms of crude only, April production was 76.8 million b/d, down 350,000 b/d month on month. Spring refining downtime took a 130,000 b/d chunk out of global supplies for the month.
