Custos Energy has provided an update on the second exploration and appraisal campaign for Blocks 2813A and 2814B in Namibia’s Orange Basin, a rapidly emerging oil and gas hub.
These blocks fall under Petroleum Exploration License 83 (PEL 83), operated by a subsidiary of Galp Energia. Custos and Namibia’s National Petroleum Corporation (NAMCOR) each hold a 10% working interest in PEL 83.
The PEL 83 Joint Venture partners have successfully drilled, cored, and logged the Mopane-3X well (Well #5), which commenced drilling on January 2, 2025.
Situated 18 km from the initial Mopane-1X well, Mopane-3X targeted two stacked prospects—AVO-10 and AVO-13—along with a deeper sand formation in the southeastern Mopane complex at a water depth of approximately 1,200 meters.
Preliminary data confirms significant light oil and gas-condensate columns within high-quality sandstones in AVO-10. Additionally, light oil columns were identified in AVO-13 and the deeper sand, both featuring excellent reservoir properties.
Reservoir log measurements indicate strong porosity, high pressures, and robust permeability. Initial fluid samples reveal low-viscosity oil with minimal CO₂ and H₂S content, with further laboratory analysis underway.
The unexpectedly high pressures and promising results at Mopane-3X unlock new exploration opportunities in the southeastern Mopane region.
Data from this well will be integrated into the reservoir model to guide future activities. Meanwhile, the proprietary 3D development seismic acquisition campaign remains on track for completion in Q1 2025, with data processing to follow.
“These latest discoveries in a previously unexplored section of Mopane highlight the scale and quality of the complex,” said Knowledge Katti, Chairman and CEO of Custos Energy.
“This world-class asset continues to reveal its multi-phase potential. We congratulate our joint venture partners on another safe and successful campaign. Custos is proud to be at the center of this promising hydrocarbon province.”
