Brazil produced 4.711 million barrels of oil per day in September, marking its fourth consecutive monthly record, according to data released Tuesday (3) by the ANP. For investors holding oil stocks, volume is only half the equation; the other half—the price of Brent crude—is controlled by no one.
Did Brazil produce more oil in September than in any previous month?
Yes, and by a comfortable margin over the previous record. According to the Monthly Production Bulletin from the National Agency of Petroleum, Natural Gas and Biofuels (ANP), September output rose 2.1% from August, which had already set the previous high. This marks the fourth straight month the record has been broken.
A year-over-year comparison highlights the scale of the shift: production is up 20.3% from September 2025. Based on ANP figures, the country produced roughly 3.9 million barrels per day that month, adding nearly 800,000 daily barrels over twelve months. Squeezing one-fifth more oil out of the ground (or rather, the seabed) in a single year is not just a strong month—it is a structural shift.
Where did these new barrels come from? The answer also explains why the news impacts individual companies differently.
Drivers of the record: Petrobras pre-salt fields and an Equinor asset
The ANP points to pre-salt fields in the Santos Basin as the primary drivers. Búzios maintained its lead among producers, followed by Tupi and Mero. All three are operated by Petrobras and together account for more than half of Brazil's oil production. Based on the figures below, they represent roughly 60% of the total.
The fourth name on the list saw the most change during the month. Bacalhau is operated by Norway's Equinor rather than Petrobras, and it posted the largest proportional jump among the fields cited by the ANP. In mid-September, Equinor CEO Anders Opedal stated at a conference that the Bacalhau FPSO platform was producing close to its capacity of 220,000 barrels per day and should reach that plateau level later this year.
Output rose by 30,100 barrels per day, a 26.4% gain in one month. Even so, the ANP figure for September equals about 65% of the platform's capacity, leaving a gap of 75,800 bpd before it reaches the plateau cited by Equinor's executive. If that full volume came online, all else being equal, it alone would lift national production by roughly 1.6% over September levels. The record, therefore, has not yet exhausted existing installed capacity.
What about natural gas? Did total oil equivalent barrels also hit a record?
Yes. The ANP reported combined oil and natural gas production of 6.120 million barrels of oil equivalent per day (boe/d) in September. The previous record was set in August, the first month the total surpassed 6 million boe/d. The figure confirms preliminary data reported last week by Broadcast, the news service of Grupo Estado.
Natural gas alone reached 223.98 million cubic meters per day, up 1.6% from August and 17.5% from September of last year. Gas is growing at a slightly slower pace than oil (20.3% over twelve months), which helps explain why discussions focus primarily on the barrel. For equity investors, the key question is different: does all this volume translate into profit?
Does a production record mean higher profits for Petrobras and other oil companies?
Not automatically. An oil company's revenue is roughly volume times price, and the ANP only measures the first half of that equation. In Tuesday's trading, Brent crude traded at $103.36 per barrel, down 1.35% on the day. With the barrel at that level, higher production tends to boost cash flow; if prices drop sharply, volume gains would be partially offset. As we noted in our coverage of crude falling internationally amid U.S.-Iran negotiations, oil prices can move quickly for reasons entirely unrelated to Brazilian production.
There is also a distinction that headline figures obscure: ANP data reflects the entire country, not any single company. Búzios, Tupi, and Mero are operated by Petrobras, but Bacalhau, which grew the most during the month, belongs to Equinor. To gauge the impact on the Brazilian company, the relevant figure is Petrobras's own production report, similar to the record production the company disclosed in October.
The equation also has an external dimension. Higher pre-salt output strengthens Brazil's export profile even when international prices fluctuate, and the country has continued setting shipment records, as we detailed in our report on record oil exports in September.
The data reinforces the operational fundamentals of energy producers listed on the B3: the thesis that volume is growing remains intact. However, volume alone is not a reason to buy or sell. Quarterly results will depend on that volume combined with Brent prices and the exchange rate. Current shareholders do not need to take action based solely on this bulletin; prospective investors should check the price of crude before looking at production records.
What should investors monitor moving forward?
The September bulletin is a snapshot of the past; the key question now is whether the streak of records will continue. To track prices on the other side of the equation, the live oil price dashboard provides up-to-date market quotations.
Bacalhau heading toward its plateau — September production reached 144,200 bpd, while Equinor targets 220,000 bpd later this year. Each step in that direction supports national output growth.
A fifth consecutive record? — The next ANP bulletin, featuring October data, will show whether production stays above September's 4.711 million bpd. A lower figure would not invalidate the investment thesis, but it would break the streak.
Brent crude — The barrel traded at $103.36 in this latest release. Price is what turns volume into revenue; a sharp pullback dampens the profit impact of production records.
