Petrobras completed the acquisition of a stake and assumed operation of exploration Block 3, located off the coast of São Tomé and Príncipe, reinforcing a new step in its strategy to expand its presence in offshore assets in Africa.
The transaction follows up on the announcement made by the company on April 17, 2026, and marks the finalization of the deal. From now on, the company will operate the block with a 75% stake, while Oranto will retain 15% and the National Petroleum Agency of São Tomé and Príncipe will hold the remaining 10%.
Petrobras strengthens its exploration portfolio
With this acquisition, the Brazilian company continues to strengthen its exploration strategy in new oil frontiers. The company seeks to increase its oil and gas reserves through projects both in Brazil and in international markets, following the guidelines established in its Business Plan.
Likewise, the operation contributes to diversifying Petrobras’ portfolio of exploration assets through opportunities with development potential in offshore regions considered strategic for the growth of the energy sector.
Consortium for the development of Block 3
The new consortium brings together Petrobras as operator, along with Oranto and the National Petroleum Agency of São Tomé and Príncipe. This structure will allow progress to be made in the next phases of geological and exploratory evaluation of the block located off the coast of the African country.
Petrobras’ majority stake reinforces its role as the entity responsible for technical and operational activities, including the planning of exploration programs that will determine the area’s resource potential.
Strategy focused on business sustainability
The company stated that this acquisition aligns with its objective of strengthening reserve replacement and generating long-term value through investments in offshore exploration.
The addition of Block 3 expands Petrobras’ international presence and is part of a strategy focused on maintaining a diversified portfolio of oil and gas opportunities, supporting the sustainability of its future operations.
