Brazil Oil Output Hits Record 4.5 Million Barrels a Day in June, Up 19%

Energy: Brazil

Brazil’s oil industry logged its strongest month on record in June, with deepwater pre-salt fields propelling national output to 4.475 million barrels a day even as Petrobras nears the finish line on its first, closely watched exploratory well off the mouth of the Amazon.

Record production numbers

Brazil produced 4.475 million barrels of oil per day in June 2026, a new all-time monthly high, the National Agency of Petroleum, Natural Gas and Biofuels — the regulator known as ANP — reported on August 3. The figure marked a 4% increase over May and a 19.1% jump from June 2025, according to the agency’s monthly production bulletin covered by G1/Globo and BNamericas.

The new mark eclipsed the previous record of 4.340 million barrels a day set just two months earlier, in April — itself the third consecutive monthly record at the time, as The Rio Times reported. Combined with natural gas, Brazil’s total hydrocarbon output reached 5.842 million barrels of oil equivalent a day in June, also a record, per the ANP data cited by BNamericas.

The surge arrived as global markets absorbed supply shocks elsewhere. A report from Investing.com carried by Yahoo Finance noted that Brazil’s climbing output, alongside gains from other non-OPEC producers, helped offset supply disruptions tied to the conflict between the United States and Iran, which had threatened shipping through the Strait of Hormuz — a corridor that normally carries about one-fifth of global oil supply.

Deepwater drives the surge

The pre-salt layer — the deepwater band of crude trapped beneath thousands of meters of ocean, rock and salt off Brazil’s southeastern coast — remained the country’s dominant source of supply. Pre-salt wells produced 3.699 million barrels of oil a day in June, part of a combined 4.788 million barrels of oil equivalent that made up 82% of national output, according to BNamericas’ reading of the ANP bulletin. Pre-salt output alone rose 24% year-on-year.

Petrobras, Brazil’s state-controlled oil company, drove much of the gain. Fields it operates — either fully owned or through partnerships — accounted for 87.08% of the country’s total oil and gas production in June, per the same ANP data. The company’s own second-quarter results, covering April through June, showed record production of 3.34 million barrels of oil equivalent a day, up 14.1% year-on-year, while its total operated production, including partners’ shares, hit a record 4.87 million boe/d, according to World Oil and a Petrobras earnings release carried by The Globe and Mail.

The Búzios field in the Santos Basin, Petrobras’ flagship pre-salt asset, led the way: ANP field-level data put its June output at 1.02 million barrels a day, the country’s largest single field. Petrobras said Búzios platforms — boosted by the ramp-up of the P-78 and newly started P-79 floating production units — crossed 1.1 million barrels a day on June 23 and 1.2 million on June 26, per World Oil. June was the first month Búzios averaged above 1 million barrels a day, making it only the second Brazilian field ever to do so, after Tupi, as The Rio Times reported. The FPSO Almirante Tamandaré, also at Búzios, was the country’s single highest-output oil facility, at 253,801 barrels a day.

Foz do Amazonas milestone

Even as Brazil’s established pre-salt fields set records, attention has turned to a very different frontier: the Foz do Amazonas Basin, off the coast of Amapá state. There, Petrobras is drilling the Morpho well, its first exploratory well on the Brazilian Equatorial Margin, roughly 175 kilometers offshore in waters 2,887 meters deep, using the Foresea-operated drillship ODN-II, according to S&P Global Commodity Insights.

Drilling began on October 20, 2025, a day after Brazil’s environmental agency IBAMA granted the license Petrobras had sought for more than a decade, having rejected an earlier bid in 2023. The campaign was interrupted in January 2026 after roughly 18.44 cubic meters of synthetic drilling fluid leaked from auxiliary lines on the rig, prompting a temporary halt, an IBAMA fine of R$2.5 million, and a pause before ANP authorized the resumption of work in February, according to Reuters and G1/Globo.

Petrobras now expects to finish drilling Morpho in August, potentially stretching into the first week of September, chief executive Magda Chambriard told Estadão/Broadcast, adding “we won’t get into October,” according to reporting picked up by Tribuna do Sertão. Exploration and production director Sylvia Anjos said on July 30 that the drillship was roughly 500 meters from reaching the target reservoir, with a report cited by G1/Globo. Completing the well is not the same as a commercial discovery: results have not been made public, and any move to production would require a fresh round of environmental licensing from IBAMA.

What it means for revenue and OPEC dynamics

Brazil’s rising output is reshaping its role in global oil markets at a moment of geopolitical stress. The Yahoo Finance/Investing.com report noted that gains from Brazil and other producers outside the Organization of the Petroleum Exporting Countries have helped cushion the impact of the US-Iran conflict on global supply, complicating earlier forecasts of an oil glut driven by non-OPEC growth.

For Petrobras, the record quarter reinforces the payoff from a heavy pre-salt investment cycle, including the early, three-months-ahead-of-schedule startup of the P-79 platform on May 1, which helped push Búzios output sharply higher within weeks, per World Oil. The company’s 2026-2030 business plan allocates roughly US$109 billion in total investment, with US$7.1 billion earmarked for exploration — including US$2.5 billion for the Equatorial Margin — as part of a broader push to keep replenishing reserves once pre-salt fields plateau, according to Reuters.

The Foz do Amazonas campaign carries outsized symbolic and financial weight. Government estimates cited by G1/Globo put recoverable resources in the Foz do Amazonas Basin at 6.2 billion barrels of oil equivalent, with the wider Equatorial Margin potentially supporting production of up to 1.1 million barrels a day — though full-scale output, if reserves are confirmed, would likely take seven to eight years to materialize, according to reporting from DeSmog.

Environmental and regulatory outlook

The Foz do Amazonas project remains under close regulatory and environmental scrutiny. IBAMA’s approval of the Morpho well in October 2025 came after a years-long licensing process, including a rejected 2023 application and a subsequent overhaul of Petrobras’ environmental studies and emergency-response planning, according to S&P Global.

The January fluid leak underscored the risks regulators are watching closely. IBAMA classified the released synthetic-based fluid as posing a medium risk to human health and aquatic ecosystems under Brazilian pollution-control law, and fined Petrobras R$2.5 million even as the company maintained the substance was biodegradable and non-toxic, per G1/Globo. ANP subsequently allowed drilling to resume only after Petrobras agreed to reinforced technical and safety conditions.

Morpho is designed as the first of up to 15 wells Petrobras plans to drill across the Equatorial Margin through 2030, meaning the regulatory posture IBAMA and ANP take toward this single well is likely to set the template for a much larger campaign, according to Brazil Energy Insight. Any confirmed commercial discovery would still require a new environmental license from IBAMA before Petrobras could move from exploration to production.
