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.
