United Kingdom

516 fields and 282 companies on the UK Continental Shelf can be followed in OESA, with data from NSTA, Sodir and GLEIF – LEI register (Level 1 and 2). The figures are in the source's unit with period and source.

The data

What the source has for the country. What is not listed here is not in the data and is not filled in.

Level: Full data. Government data with owners, shares and production per field.
Ownership: per field, with shares
Production: per field and month, all fields in the country
Facilities: not in the source
Pipelines: from the source
Period for the totals: Aug 2025–Jul 2026
Retrieved: 8 Oct 2026

Notes

What the sources and OESA say about the data for the country, including what is not used.

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 · 8 Oct 2026
NSTA has no share history. OESA keeps its own snapshots of the shares from 8 Oct 2026; changes before that are unknown. NSTA · 8 Oct 2026
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. NSTA · 8 Oct 2026
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. NSTA · 8 Oct 2026
4 wells are being drilled now from semi-submersible rigs whose name NSTA does not give. NSTA · 8 Oct 2026
