Field · the network on the UK Continental Shelf
Nelson
Nelson is an oil field on the UK Continental Shelf, operated by Adura Energy. The map shows the owners.
Estimate: Converted from the source's figures (Aug 2025–Jul 2026). 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%.
Estimate: 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%. 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 field's production in oil equivalent (Aug 2025–Jul 2026) divided by the total for all fields in the source. 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.

The network
From owner to landfall. Links without their own label have their source in the column heading; curated and derived links are labelled at the link.
- 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.

Production per month
The source's figures in the source's unit. The oil equivalents in the key figures are converted by the Norwegian Offshore Directorate's rule.

Licences
The licences the field lies in, with the licensees as the source states them. A licence share is not a field share.
LicencesNSTA · 8 Oct 2026
| Name | Type | Operator | Licensees |

Notes
- 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.
