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.
