Well Discovered by Petrobras in the Pre-Salt of the Santos Basin Reveals High-Quality Oil and Reinforces the Country’s Potential as a Global Energy Leader.
A new oil discovery in Brazil, announced by Petrobras, promises to boost national production and bring high revenue values to the country. Drilling in the Aram block, in the pre-salt of the Santos Basin, revealed a reservoir with high-quality oil, strengthening Brazil’s strategic position in the international energy market.
Petrobras Confirms New Well in the Santos Basin
Petrobras announced on May 9, 2025 the discovery of an oil well. The field is located in the Aram block, in the pre-salt of the Santos Basin. Drilling is approximately 248 km from the coast of the city of Santos, in São Paulo, and reached a depth of 1,952 meters. Initial samples indicate that the oil found is high-quality.
The operation is led by Petrobras, which holds 80% stake in the consortium. The remaining 20% belongs to the Chinese state-owned company China National Petroleum Corporation (CNPC). The goal of the exploration is to confirm a large volume of reserves, which could solidify Petrobras’s presence in the global market.

The Strategic Relevance of Brazilian Pre-Salt
Located in the southern part of the Santos Basin, the Aram block reinforces the strategic importance of the region. The project gains even more relevance due to the excellence of the oil found, which is light and contaminant-free.
In addition to strengthening Petrobras, the exploration promises to expand the country’s production capacity. This positions oil in Brazil more competitively in the international arena. The expectation is for high revenue generation for the nation.
Phase of Analysis and Future Investments in the Aram Block
After the drilling of the well, identified as 3-BRSA-1396D-SPS, Petrobras begins the phase of laboratory analysis. The goal is to define the detailed characteristics of the reservoirs and the fluids found.
The company plans to drill new wells in the area. This phase is part of the Discovery Assessment Plan, which is expected to extend until 2027. Investment in technology, such as the use of floating platforms, will be essential to maximize oil extraction. The Aram block operates under the production sharing regime, which promises high profitability and attracts significant investments.
Economic Impact and Energy Security for the Country
The discovery in the Aram block has the potential to transform Brazil into a energy leader. The increase in oil production in Brazil may generate new jobs and also a higher tax revenue for the government.
Additionally, the new source contributes to the energy security of the country. With higher production, Brazil can reduce its dependence on oil imports, strengthening its autonomy in the sector.
