Oil and gas production per operator and field

Coverage. Up to Dec 2023 the data is ANP's complete monthly per-well file. ANP stopped publishing that file; from 2024 on, the per-well data on this page comes from MANUAL exports of ANP's public query (a CAPTCHA that this site never automates), so coverage is PARTIAL. Offshore (Mar) is loaded for Jan 2024 to Sep 2026. Onshore (Terra) is missing for: Jan 2024 to Aug 2025; so 2024 and 2025 have no onshore at all. Pre-salt files: none loaded, so the pre-salt share is not shown for those months. Where Terra is missing the month is labelled 'offshore only', no operator ranking adds Mar to a missing Terra and no 12-month change is computed against a month with a different scope. For months with an ANP Monthly Bulletin (up to Aug 2026) and no Terra file, the operators come from the Bulletin (all operators, offshore + onshore, no field).

• Oil (bbl/day): oil plus condensate, in barrels per day. It is the daily average rate of the month, as ANP publishes it; it is not the month's volume. The sum of the wells' rates is the rate of the field or of the operator (our sum).
• Natural gas (Mm³/day): associated plus non-associated, in thousand cubic metres per day (Mm³ = 1,000 m³). In the cards, the conversion to million m³ per day is ours (÷ 1,000). It is gas produced, not sold: it includes what is reinjected, flared or used on the platform.
• Pre-salt: the share of oil from wells inside the pre-salt polygon, as ANP separates it in its pre-salt file (a subset of offshore, never added again). The percentage share is ours.
• Share: the operator (or field) divided by the national total of the month, in %. Ours.
• Change 12m: the month's oil against the same month a year earlier, in %. Ours. When the operator's name changed between the two years (ANP renames), there is no change.
• The operator is ANP's, not the stock: the file gives the operator's trade name, with no tax ID. The tax ID comes from ANP's list of concessionaires, by contract number, and only counts when the operator's name in the month equals the contract operator's current name (fields change hands). We only link to a stock when that full tax ID is the one of a company with a ticker; an SPE or consortium operator has its own tax ID and stays unlinked. No group is deduced from a name.

• /petroleo/producao — operators of the latest month, in JSON.
• /petroleo/producao?nivel=campo — fields of the latest month.
• /petroleo/producao?formato=csv — CSV.
• /petroleo/producao?cnpj=33000167000101, ?operador=Petrobras, ?campo=TUPI — the monthly series of one operator or field (with de and ate, YYYY-MM).

What the source published is the daily average rate of each well. Our calculations are the sums per operator and per field, the share of the national total, the change against the same month a year earlier, the pre-salt share and the conversion of Mm³ to million m³. It is a regulator aggregate that nobody rebuilds from a public company filing, so it lives in the Macro section.
