Petrobras has completed the acquisition of a 75% operated interest in Block 3 offshore São Tomé and Príncipe, marking another step in the company's strategy to expand its exploration portfolio beyond Brazil.
The transaction follows the agreement announced earlier this year and establishes a consortium comprising Petrobras (75%, operator), Oranto (15%) and the National Petroleum Agency of São Tomé and Príncipe (10%).
Located in the underexplored waters of the Gulf of Guinea, the block forms part of a region that has attracted growing industry interest due to its geological similarities with neighbouring hydrocarbon provinces along the West African Transform Margin.
Petrobras says the acquisition supports its long-term strategy of replenishing oil and gas reserves through exploration in both domestic and international frontier basins.
The move also reflects the continued strategic importance of frontier exploration, where advances in seismic imaging and regional geological understanding are helping companies evaluate emerging opportunities across offshore Africa.
