Production per month

The source's figures in the source's unit. The oil equivalents in the key figures are converted by the Norwegian Offshore Directorate's rule.

Contracts

The contracts the field lies in, with the licensees as the source states them. A share in a contract is not a field share.

Rigs

The rigs the source lists on the field.

Notes

• The figures are shown as ANP states them. Production by ownership share (share × production) is OESA's own calculation, not ANP's figures.
• ANP only publishes the current distribution of shares. OESA keeps its own snapshots from 8 Oct 2026; changes before that are unknown.
• The production is ANP's «Produção por zona» per field and month (Aug 2025–Aug 2026): oil and condensate in m³, gas («Gás total», associated and non-associated gas) in 1,000 m³. ANP gives averages per day; OESA has multiplied by the number of days in the month. The gas is gross produced gas. Gas that is reinjected is a separate column at ANP and is not subtracted. The oil equivalent is therefore higher than with sales gas, which the Norwegian Offshore Directorate uses for Norway.
• ANP splits some fields into several contract areas (for example BÚZIOS and BÚZIOS_ECO). The same well can appear in several areas, but ANP gives a separate part of the production for each area, and OESA only adds up what ANP gives per area.
• The contracts (relação de concessionários) have their own participant shares per contract. They are not field shares and are never combined with the field's production.
• 6 non-contracted areas (AnC_*, área não contratada) have production at ANP but no licensee. Their production is included in the country total but attributed to no one.
• Facilities and pipelines are ANP's map layers (GeoANP) as stored by OESA on 26 Sep 2026 and 28 Sep 2026. Operator and owner are given as ANP writes the name, without CNPJ, and are not merged with the companies holding shares.
• The rigs are ANP's list of rigs in operation per field in 2026, with the rig operator. The list gives no well or date.
