ConocoPhillips said production has resumed from both the Eldfisk and Embla fields in the Norwegian North Sea.
The fields had been shut down on New Year’s Eve along with the Valhall platform after a drifting vessel moved towards them.
BP previously announced production had already resumed from the Valhall field.
Ekofisk crude oil stream represents one of four North Sea crudes supporting the global Brent oil benchmark.
ConocoPhillips’ Embla and Eldfisk fields form a part of the Ekofisk crude oil stream.
Earlier today it was revealed BP, ConocoPhillips and the Norwegian military had been in discussions about options for preventing the barge from moving any closer to the fields.
