Portugal’s Galp, Brazil’s Petrobras, U.K.’s Shell and Agência Nacional do Petroléo de São Tomé e Principé (ANP-STP) have formed a joint venture focused on early-stage exploration block offshore the African country.

Galp has reached a farm-in agreement with KE STP Company, a Shell affiliate, for a 27.5% stake in Block 4 in São Tomé and Príncipe, expanding its exploration interest in the country.

Also, Petrobras acquired the 27.5% stake in the same block, forming a joint venture with the operator of the asset Shell (30%), ANP-STP (15%), and Galp (27.5%).

Petrobras has been active in São Tomé and Príncipe since February 2024, when it acquired a 45% stake in Blocks 10 and 13, and a 25% stake in Block 11.

In São Tomé and Príncipe, Galp also holds participations in Blocks 6 (45%, operator), 11 (20%) and 12 (41.2%, operator).

“This transaction strengthens Petrobras’ exploratory activities on the African continent, with the purpose of portfolio diversification, and is aligned with the company’s long-term strategy, aiming to replenish oil and gas reserves through exploration of new frontiers and partnership operations,” Petrobras said following the acquisition.
