Notes
- The production by share is not calculated for Jul 2025–Jun 2026 (BOEM). The reason: 1 field or licence where the source's shares cannot be used for calculation. G35867: BOEM gives different shares for different parts of the lease (the owner groups). The source does not say which part the production comes from, so the share is not used in calculations.
- The ownership history is BOEM's own: each assignment has an effective date, and a share applies from that date until the day before the next change. Shares that ended before 2020 are not included.
- The leases in the Gulf of Mexico are included when they belong to a field in BOEM's field list or have production in Jun 2025–Jun 2026. 1176 leases with current owners, most of them in the exploration term, are not included in the overview.
