Notes
- BOEM's shares are record title shares per lease. They are not the participation shares in the unit agreements, which are not public, and not necessarily the working interests (operating rights). The fields therefore have no ownership shares; the shares are per lease, and production by share is calculated per lease.
- 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.
- The share estimate per field is OESA's calculation: the record title share in each lease in the field, weighted by the lease's production from the field in oil equivalent (Jul 2025–Jun 2026), with the share that applied in each month. It is not the field's ownership and is not used in sums; the sums are calculated per lease.
- Alaska OCS: BOEM has owners and operator for the leases, but no production figures. AOGCC blocks scripts, and the block is not bypassed. Which fields the leases belong to is not in BOEM's field list.
