Luanda, September 10, 2026 – On the occasion of the Angola Oil & Gas Conference, Patrick Pouyanné, Chairman and CEO of TotalEnergies, announced several exploration successes.

Acacia-5: from discovery to production in 3 months

TotalEnergies (38%, operator) has announced the Acacia-5 near-by discovery on Block 17. First Oil will be achieved only three months after the discovery made in June 2026, through a fast-track development leveraging the available capacity on the Pazflor FPSO. Acacia-5 shall increase Block 17 production by 6,000 barrels per day.

Acacia-5 is the second exploration success recorded in 2026 across TotalEnergies' Angolan portfolio, following the recent Block 0 discovery in the prolific Lower Congo Basin, where TotalEnergies holds a 10% interest alongside Chevron, operator.

TotalEnergies has signed agreements with the concessionaire Agência Nacional de Petróleo, Gás e Biocombustíveis (ANPG), to enter with a 40% operated interest in exploration Blocks 17/25 and 32/21, located in the heart of the prolific Lower Congo Basin.

These promising blocks benefit from extensive existing 3D seismic coverage and offer access to several prospective geological plays. They are located close to existing facilities in TotalEnergies-operated Blocks 17 and 32, where six FPSOs are currently producing, therefore allowing for future tie-backs and cost-efficient development of additional resources through existing facilities.

Moreover, TotalEnergies signed in February 2026 a Head of Agreement (HoA) with ANPG, and ExxonMobil to farm-in with a 35% interest into exploration Blocks 40, 41, 42 and 58 in the Benguela Basin.

“I am very pleased to announce these exploration successes in Angola, which demonstrate both the attractiveness of the country and our confidence in its future. Exploration is a key pillar of our ambition in Angola, supported by the incentives introduced to encourage investment. Together with our partners, we aim to explore further and unlock new resources, sustaining a strong exploration effort to identify new opportunities across Angola's offshore basins”, said Patrick Pouyanné, Chairman and CEO of TotalEnergies.

TotalEnergies holds a 38% operated interest in Block 17, alongside Equinor (22.16%), ExxonMobil (19%), Azule Energy (15.84%) and Sonangol E&P (5%). TotalEnergies holds a 40% operated interest in Blocks 17/25 and 32/21, alongside ExxonMobil 40%, and Sonangol E&P 20%. TotalEnergies holds a 10% interest in Block 0, alongside Sonangol E&P (41%), Chevron (39.2%, operator) and Azule Energy (9.8%).
