Calculated equity production, last 12 months: 1.62 million Sm³ o.e.; Estimate · Aug 2025–Jul 2026 · NSTA · 8 Oct 2026
Per day: 28,000 barrels o.e./day; Estimate · Aug 2025–Jul 2026 · NSTA · 8 Oct 2026
Share of production in the United Kingdom: 2.77%; Estimate · Aug 2025–Jul 2026 · NSTA · 8 Oct 2026
Fields with a stake: 28; NSTA · 8 Oct 2026
Licences with a share or operatorship: 12; NSTA · 8 Oct 2026

Estimate: Calculated by OESA, not figures from the company: for each field the share that applied in each month is multiplied by the production from NSTA (Aug 2025–Jul 2026), converted to oil equivalent and summed over 15 fields and licences. Some shares are stated as of 8 Oct 2026 and may have differed earlier in the period. Some shares are truncated by the source. 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. Estimate: the source gives m³ without reference conditions, and the figure is treated as Sm³. The error can be up to about 5%. The figure applies in the United Kingdom 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.

Estimate: The calculated equity production divided by the total for all fields in the source (Aug 2025–Jul 2026), both in oil equivalent. The total for the country is over 233 of 289 fields with production in the period; 56 fields that started or stopped in the period are left out of both.

Notes

The shares are legal ownership shares at NSTA, not the company's reported production.
NSTA's field layer gives the shares in whole percent, truncated (97.13915 is shown as 97). The sum for a field can be below 100%, and share × production then comes out slightly low. For 68 fields the shares with decimals from a subarea in NSTA's licence subareas are used: the subarea carries the field name, exactly the same licensees, shares that truncate to the field layer's whole percent and a sum of 100%.
NSTA has no share history. OESA keeps its own snapshots of the shares from 8 Oct 2026; changes before that are unknown.
The production is NSTA's PPRS figures per field and month: oil and condensate in m³, gas (associated and dry gas combined) in 1,000 Sm³. Fields reported in parts are the sum of the parts. Coal mine vents are not included.
The operator is NSTA's organisation group (for example APACHE CORPORATION), not the legal company holding the share. NSTA does not link installations and pipelines to fields; they are listed under the operator. Only pipelines in use carrying oil, gas, condensate, mixed hydrocarbons or CO₂ are included.
