TotalEnergies has restarted hydrocarbon exploration on Block 2913B in Namibia’s Orange Basin, drilling the Tamboti-1X exploration well just north of the Venus accumulation. The company estimates the target holds around 1 billion barrels of oil.
The Deepsea Mira rig, operating under a multi-country contract with TotalEnergies since December 2022, began drilling the well in October 2024.
TotalEnergies leads operations on Block 2913B in PEL 56, holding a 50.5% stake in the 8,215-square-kilometer offshore area. Its joint venture (JV) partners include QatarEnergy (30%), Africa Oil’s Impact Oil and Gas (9.5%), and Namibia’s NAMCOR (10%).
Africa Oil’s Impact has completed drilling and testing at Tamboti-1X and has now spudded the Marula-1X exploration well in the same block. The Tamboti-1X well struck black oil in 85 meters of net reservoir within low-quality Upper Cretaceous sandstones of the Mangetti fan system.
Impact confirmed that the drill stem test (DST) program has concluded, with log, core, and DST data currently under evaluation. On February 3, 2025, the Deepsea Mira rig initiated drilling at Marula-1X, located in the southern part of Block 2913B. The JV aims to tap into Albian-aged sandstones within the Marula fan complex.
According to the JV, this well could unlock additional exploration prospects in the southern region, which lies within the Kudu source-rock kitchen. Additionally, the JV plans to drill the Olympe prospect on Block 2912, targeting Albian sands within a structural closure, by the end of 2025.
