Baixa do Algodão
Baixa do Algodão is a field in Brazil, operated by Mandacaru Energia S.a. The map shows the owners.
Estimate: Converted from the source's figures (Sep 2025–Aug 2026). Oil equivalent by the Norwegian Offshore Directorate's rule: oil, condensate and NGL in Sm³ count equally, 1,000 Sm³ of gas = 1 Sm³ o.e. and 1 tonne of NGL = 1.9 Sm³ o.e. Estimate: the source gives m³ without reference conditions, and the figure is treated as Sm³. The error can be up to about 5%. ANP gives the production as an average per day in the month (m³/d and thousand m³/d). OESA has multiplied the average by the number of days in the month to get the monthly volume, assuming ANP averages over all days of the month.
Estimate: Oil equivalent by the Norwegian Offshore Directorate's rule: oil, condensate and NGL in Sm³ count equally, 1,000 Sm³ of gas = 1 Sm³ o.e. and 1 tonne of NGL = 1.9 Sm³ o.e. Estimate: the source gives m³ without reference conditions, and the figure is treated as Sm³. The error can be up to about 5%. Per day: Sm³ o.e. × 6.29 barrels per Sm³ divided by the number of days in the period. Rounded to the nearest 10 below 1,000, the nearest 100 below 10,000 and the nearest 1,000 above that.
Estimate: ANP gives the production as an average per day in the month (m³/d and thousand m³/d). OESA has multiplied the average by the number of days in the month to get the monthly volume, assuming ANP averages over all days of the month.
Estimate: The field's production in oil equivalent (Sep 2025–Aug 2026) divided by the total for all fields in the source. The total for the country is over 230 of 296 fields with production in the period; 66 fields that started or stopped in the period are left out of both.

The network
From owner to landfall. Links without their own label have their source in the column heading; curated and derived links are labelled at the link.
- The colour shows the content:
- Gas
- Oil
- Condensate
- CO₂
- Oil and condensate
- The line shows the source:
- pipeline in ANP data
- curated, with the source at the link
- possible onward route, not measured flow
- planned or not in service
The links show direction, not volume.

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.
- 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.
