In a significant boost for the global energy sector, BP has announced its largest oil and gas discovery in 25 years at the Bumerangue prospect in Brazil’s deepwater Santos Basin. This find underscores Brazil’s growing importance as a hydrocarbon powerhouse and positions BP to strengthen its upstream portfolio amid shifting energy dynamics. Let’s dive into the details of this discovery, its potential implications for Brazil’s oil exports, and the anticipated impact on BP’s financial performance.
The Bumerangue Discovery: A Game-Changer in the Pre-Salt Basin

The Bumerangue exploration well, designated as 1-BP-13-SPS, was drilled to a total depth of 5,855 meters in water depths of 2,372 meters, approximately 404 kilometers offshore from Rio de Janeiro.
The well intersected a high-quality pre-salt carbonate reservoir, penetrating an estimated 500-meter gross hydrocarbon column across an areal extent exceeding 300 square kilometers.
Initial rig-site analysis confirmed the presence of oil and gas, along with elevated levels of carbon dioxide, though further laboratory evaluations are needed to fully characterize the fluids and reservoir quality.
BP holds a 100% interest in the Bumerangue block, which it acquired in December 2022 during Brazil’s first Production Sharing Open Acreage cycle.
Pré-Sal Petróleo S.A. serves as the manager of the Production Sharing Contract, with favorable terms including 80% cost oil recovery and a low 5.9% profit oil share to the government, leaving BP with the lion’s share of profits after costs.
This marks BP’s tenth discovery of 2025, following finds in regions like Trinidad, Egypt, and the Gulf of Mexico, but Bumerangue stands out as potentially the company’s biggest since the Shah Deniz gas field in the Caspian Sea in 1999.
While official reserve estimates have not yet been released, the scale of the hydrocarbon column and areal extent suggest substantial potential. Comparable pre-salt discoveries in Brazil, such as those in the nearby Buzios field (estimated at 10-13 billion barrels of recoverable oil), indicate that Bumerangue could hold billions of barrels of oil equivalent (boe).
Analysts note that the find’s size—described as a 500-meter column—positions it as a major addition to global reserves, though appraisal drilling and regulatory approvals will be crucial for confirming commercial viability.
BP plans further appraisal activities and has an exploration well scheduled for the adjacent Tupinambá block in 2026.
Implications for Brazil’s Oil Exports
Brazil has rapidly emerged as one of the world’s top oil producers, thanks to its prolific pre-salt basins. In 2024, the country’s oil production averaged around 3.2 million barrels per day (bpd), with exports hovering between 1.5 and 2 million bpd, primarily to markets in Asia and Europe.
The Bumerangue discovery reinforces Brazil’s status as a key frontier for energy development, attracting international majors like BP, Equinor, and Shell to its deepwater plays. However, the immediate impact on 2025 exports will be minimal, as bringing such a discovery online typically takes 5-7 years, involving appraisal, development planning, and infrastructure buildout. Looking longer-term, Bumerangue could significantly enhance Brazil’s export capacity. If developed into a production hub, it might add 200,000 to 500,000 bpd of output by the early 2030s, based on production profiles of similar pre-salt fields.
This aligns with Brazil’s national goals to ramp up production to over 5 million bpd by 2030, potentially elevating its export volumes to 3 million bpd or more. The discovery also highlights the attractiveness of Brazil’s regulatory framework, with low government take in profit oil making it competitive against other basins. As global demand for oil persists amid the energy transition, Bumerangue could help Brazil solidify its role as a stable supplier, reducing reliance on Middle Eastern sources and contributing to energy security worldwide.
Boost to BP’s Bottom Line
For BP, Bumerangue represents a timely win as the company refocuses on fossil fuels to drive shareholder returns. BP’s 2024 production stood at 2.4 million barrels of oil equivalent per day (boed), but it anticipates a dip in 2025 due to divestments and maintenance.
The company aims to grow upstream output to 2.3-2.5 million boed by 2030, with scalability beyond, and this discovery plays a pivotal role in achieving that target.
Assuming recoverable reserves in the range of 5-10 billion boe (drawing parallels to Shah Deniz’s scale), Bumerangue could generate substantial revenue over its lifecycle. At a conservative oil price of $60 per barrel, this might translate to $300-600 billion in gross revenue, though net figures would account for development costs (estimated at $10-20 billion for a field of this size), operating expenses, and the profit-sharing structure.
With BP’s 100% stake and favorable PSC terms, the company could see an annual revenue boost of $2-5 billion once at peak production, assuming 300,000-500,000 boed output.
This would enhance BP’s free cash flow, supporting dividends, buybacks, and investments in lower-carbon initiatives. Analysts view the find as a strategic lever for long-term value creation, potentially adding billions to BP’s net asset value and helping offset declines in mature fields.
Shares rose 1.7% following the announcement, reflecting market optimism.
Looking Ahead
The Bumerangue discovery is a testament to BP’s exploration prowess and Brazil’s enduring appeal in the oil industry. While challenges like high CO2 content and deepwater complexities remain, the potential rewards are immense. For Brazil, it promises economic growth through increased exports; for BP, it’s a cornerstone for financial resilience. As appraisal progresses, the energy world will watch closely to see how this “huge win” unfolds.
