Appraisal well in North Sea increases projection

Friday, September 25 2026

Drilling

Aker BP and its partners Equinor and DNO have drilled an appraisal well on the Verdandi and Lillefix discoveries in the North Sea.

This well increases the projected discovery size.

Prior to drilling, the companies presumed that the size was 0.6–1.9 million Sm3 of oil equivalent (4-12 million barrels). Preliminary calculations after drilling amount to 1.3–2.4 million Sm3 of oil equivalent (8-15 million barrels).

The companies are now considering the profitability and whether the discovery can potentially be tied back to the Symra field.

Well 16/1-EA-4 H was drilled about 200 kilometres west of Stavanger by the Deep Sea Nordkapp drilling rig. It was drilled from the subsea template on the Symra field as a horizontal appraisal wellbore.

This was the 11th exploration well in production licence 167, which was awarded in the 13th licensing round.

The water depth at the drilling site is 116 metres, and the well has been permanently plugged and abandoned.
