Marketable production in million standard cubic metres of oil equivalent (Sm³ o.e.), per month from the Norwegian Offshore Directorate, summed per year. Gas in billion Sm³ equals million Sm³ o.e. Figures up to and including August 2026. The conversion to barrels per day uses 1 Sm³ ≈ 6.29 barrels.
Reserves
The Norwegian Offshore Directorate's estimate as of 31 Dec 2025. Originally recoverable is everything the field is expected to produce; remaining is what is left.
| Product | Originally recoverable | Remaining | Unit |
|---|---|---|---|
| Oil | 0.43 | 0.01 | million Sm³ |
| Gas | 69.37 | 0.06 | billion Sm³ |
| NGL | 13.41 | 0.00 | million tonnes |
| Condensate | 26.62 | 0.00 | million Sm³ |
| Total o.e. | 121.89 | 0.07 | million Sm³ o.e. |
According to the estimate, 100 % of the recoverable reserves have been produced.
