TotalEnergies revealed a significant offshore discovery in Block 17 positioned along Angola’s Atlantic coast, with plans to commence production during the current quarter.
The new block 17 discovery will be integrated into existing production infrastructure through a tieback arrangement to the Pazflor floating production, storage and offloading vessel. This connection is expected to deliver an additional 6,000 barrels per day of production capacity, leveraging already-established facilities to optimize development efficiency and reduce capital requirements.
Operational Partnership and Stakeholder Structure
France-based TotalEnergies maintains operational control of Block 17 with a 38 percent working interest. The project encompasses a diverse international consortium, reflecting the collaborative nature of modern offshore oil and gas development. Norway’s Equinor ASA holds a 22.16 percent stake, while the United States-based Exxon Mobil Corporation retains 19 percent. The Azule Energy joint venture, equally owned by Britain’s BP and Italy’s state-backed Eni, maintains a 15.84 percent position. Angola’s national petroleum company, Sociedade Nacional de Combustíveis de Angola EP (Sonangol), owns a five percent stake in Block 17.
Recent Exploration Momentum Across Angola Portfolio
“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 percent interest alongside Chevron, operator”, TotalEnergies stated in a press release, commenting on the new block 17 discovery.
The Block 0 discovery demonstrated a hydrocarbon column exceeding 600 meters within the primary Pinda reservoir, with net pay exceeding 90 meters and exceptional reservoir characteristics, according to Chevron’s announcements.
Development discussions for the Block 0 discovery are exploring a tieback arrangement to Chevron’s existing infrastructure for the 105-4X find. Production from Block 0 has already commenced through the Mafumeira developments.
Expansion of Exploration Acreage
Concurrent with the new block 17 discovery announcement, TotalEnergies finalized concession agreements with Angola’s National Agency for Petroleum, Gas and Biofuels (ANPG).
“These promising blocks benefit from extensive existing 3D seismic coverage and offer access to several prospective geological plays”, TotalEnergies said.
“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,” it added.
Additionally, TotalEnergies entered a preliminary agreement with ANPG and ExxonMobil targeting exploration blocks 40, 41, 42, and 58 in the Benguela Basin. Under the arrangement, TotalEnergies would assume a 35 percent working interest in these prospective acreage positions.
Strategic Vision and Market Positioning
“Exploration is a key pillar of our ambition in Angola, supported by the incentives introduced to encourage investment”, said TotalEnergies chair and chief executive Patrick Pouyanné.
“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,” he added.
