Namibe basin is located in the south-central Atlantic off southern Angola. Its occurrence in Late Jurassic-Early Cretaceous continental rifting is coeval to the Santos of eastern Brazil. In this frontier-type, marginal sag basin, a 420-km sediment depocenter is estimated along a north-south elongation axis. Walvis Ridge bounds the basin's southern flank offshore, and desert sand covers the onshore strata. Regional unconformities are drawn from contiguous Kwanza and Congo basins. A potentially large reservoir is a 100-mi linear shelf-edge Albian carbonate inferred to be a buildup or bank. Other potential reservoirs are lacustrine sands/carbonates found near basement horst blocks and deep-basin Tertiary turbidites sourced from the shelf due to rapid sand deposition on a steep shelf-slope. The basin's excellent hydrocarbon potential is emphasized by marine and lacustrine source-rich shale deposition in optimal mature zones.
