Petrobras acquires 75% stake in Block 3 offshore oil field from Oranto Petroleum and ANP-STP

Type: Acquisition · Technology: Oil Gas · Country: Santo Tomé y Príncipe · Announced: 2026-07-10

Petrobras completed the acquisition of a 75% stake in Block 3, an offshore oil field located off the coast of the African republic of Santo Tomé y Príncipe, from Oranto Petroleum Limited and the Agencia Nacional de Petróleo de Santo Tomé y Príncipe (ANP-STP). The transaction follows Petrobras' announcement in April 2026, with the Brazilian state-owned company assuming operational control of the block while Oranto reduced its stake to 15% and ANP-STP retained its 10% share. The deal aligns with Petrobras' strategy to replenish its oil and gas reserves through exploration in new frontiers, both domestically and internationally, as outlined in its Business Plan. Petrobras re-entered Africa in 2024, aiming to diversify its exploration portfolio to create long-term value and sustainability. The acquisition marks a strategic expansion into African offshore oil assets, complementing Petrobras' existing global exploration activities. No financial terms or operational timelines were disclosed in the announcement.
