TotalEnergies has announced a new oil discovery on Angola’s offshore Block 17 and agreements to enter two additional exploration blocks in the Lower Congo Basin.
The Acacia-5 discovery will be developed through a tie-back to available capacity on the Pazflor FPSO. First oil is expected only three months after the discovery was made in June 2026, with production forecast to increase Block 17 output by approximately 6000 barrels per day.
TotalEnergies operates Block 17 with a 38% interest. Acacia-5 is the company’s second exploration success in Angola during 2026, following a discovery on Chevron-operated Block 0.
The company has also signed agreements with Angola’s National Oil, Gas and Biofuels Agency to acquire 40% operated interests in Blocks 17/25 and 32/21. ExxonMobil will hold 40% and Sonangol E&P the remaining 20%.
Both blocks have extensive existing 3D seismic coverage and contain several prospective geological plays. Their proximity to TotalEnergies-operated Blocks 17 and 32, where six FPSOs are producing, could support cost-efficient development through future subsea tie-backs.
