Estimate: Calculated by OESA, not figures from the company: for each field (or each licence where both the shares and the production are per licence) the share that applied in each month is multiplied by the production from BOEM (Jul 2025–Jun 2026), converted to oil equivalent and summed over 6 fields and licences. Oil equivalent by the Norwegian Offshore Directorate's rule: oil, condensate and NGL in Sm³ count equally, 1,000 Sm³ of gas = 1 Sm³ o.e. and 1 tonne of NGL = 1.9 Sm³ o.e. Converted from barrels: 1 barrel = 0.158987 m³ (42 US gallons). The source's barrels are at 60 °F and Sm³ at 15 °C; the difference is under 0.1%. Converted from Mcf: 1 Mcf (60 °F, 14.73 psia) ≈ 28.33 Sm³ (15 °C, 101.325 kPa). Not included in the sum: 2 fields or licences where the source's shares cannot be used for calculation. G35295: The shares BOEM gives for the lease do not add up to 100%, so they are not used in calculations. G36704: BOEM gives several different shares for the company in the same assignment, so the share is ambiguous and is not used in calculations. The figure applies in the United States and is not the company's global production. Per day: Sm³ o.e. × 6.29 barrels per Sm³ divided by the number of days in the period. Rounded to the nearest 10 below 1,000, the nearest 100 below 10,000 and the nearest 1,000 above that.
