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 11 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%. Not included in the sum: 1 field or licence where the production does not cover the whole period or applies to another period. 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.

The network

The fields with a stake or operatorship, with facilities, pipelines and landfall. Links without their own label have their source in the column heading.

  • The colour shows the content:
  • Gas
  • Oil
  • Condensate
  • CO₂
  • Oil and condensate
  • The line shows the source:
  • pipeline in NSTA data
  • curated, with the source at the link
  • possible onward route, not measured flow
  • planned or not in service

The links show direction, not volume.
