After dropping by 40,000 b/d in 2017, North Sea crude and condensate production will continue to fall through 2018 and 2019 as declining Norwegian output outweighs UK supply growth. By 2019, ESAI Energy expects North Sea output to have fallen below 2.7 million b/d, 65,000 b/d less than 2017 supply. However, these North Sea declines will be reversed by the late-2019 startup of the Johan Sverdrup mega-project.
