Petrobras Expands Its Operations in Africa by Acquiring 27.5% of Block 4 in São Tomé and Príncipe. The Operation Strengthens Global Partnerships and Reinforces the State Company’s Diversification Strategy.
Petrobras continues to expand its presence in the international arena. The company announced the completion of the acquisition of 27.5% stake in Block 4, in São Tomé and Príncipe, as reported by ADVFN (Advanced Financial Network) on Monday, September 15.
The move reinforces the diversification strategy and solidifies Petrobras’ operations on the African continent. The deal was made official after the close of trading last Friday, September 13.
Investment History in São Tomé and Príncipe
This is not Petrobras’ first investment in the African archipelago. In February 2024, the state-owned company had already acquired stakes in blocks 10, 11, and 13. With the new acquisition, the company strengthens its presence in a region considered strategic, especially due to its proximity to the West African coast, recognized for its potential in oil and natural gas.

Petrobras is expected to complete the drilling of the Morpho well in the Foz do Amazonas in August 2026, the first well in the Equatorial Margin, an oil frontier that the ANP estimates at more than 30 billion barrels and could redraw the map of Brazil.
In the Block 4 consortium, Petrobras joins prominent names in the energy sector: Shell, Galp, and ANP-STP. This integration highlights the search for international partnerships and reinforces the Brazilian state company’s interest in exploring new frontiers beyond the pre-salt.
In an official statement, Petrobras emphasized that the move “reinforces the company’s exploratory operations on the African continent, with the purpose of portfolio diversification.”
Impact on Investors and the Financial Market
Despite the announcement, PETR4 shares remained stable during Friday’s trading, closing at R$ 31.18. In the last 52 weeks, the shares have fluctuated between R$ 28.86 and R$ 40.76. Analysts assess that the operation may gain relevance in the medium and long term, especially due to the strategic potential for the state company’s internationalization.
Although the immediate impact was not felt on the stock exchange, experts highlight that expansion moves like this increase Petrobras’ visibility in the global market and may attract new investors looking at growth outside Brazil.
Regarded as the largest energy company in Brazil and one of the main publicly listed companies on B3, Petrobras focuses primarily on the exploration and production of oil and gas. However, it also operates in refining, transportation, and renewable energies, directly competing with international giants like Shell and BP.
The expansion in São Tomé and Príncipe reinforces the state-owned company’s strategy to reduce dependence on pre-salt oil and advance into new exploration frontiers on the African continent. The move aligns with the long-term goal of portfolio diversification and global strengthening.
