Kavango Basin versus Orange Basin Deep Maybe the source rock we are exploring for is located in Namibia's Orange Basin (offshore) and is migrating and feeding traps in Namibia's Orange basin and not the Kavango basin.
The super majors are exploring this Orange basin offshore. https://oilprice.com/Energy/Crude-Oil/Supermajors-Are-Flocking-To-This-Booming-Oil-Frontier.html Offshore Namibia, research indicates that Namibia’s Orange Basin has similar a source rock to Brazil. 
That’s why Exxon Mobil (NYSE:XOM) moved to expand its exploration acreage last year, adding another 28,000 square kilometers to its offshore holdings, with depths reaching 4,000 meters. This is in addition to XOM’s 40% stake on another 11,500-sq-km offshore oil and gas license in Namibia.
French oil giant Total SA (NYSE:TOT) is gearing up right now to start a three-well drilling campaign that includes one of the deepest wells ever drilled in Africa - two wells in Angola and one in Namibia. Drilling will start this month, with Maersk’s Voyager rig.
The potential hasn’t escaped Qatar Petroleum, which is farming into Total’s Namibia blocks.
Shell (NYSE:RDS.A) is also delineating a deep-water wildcat prospect offshore Namibia, planning to spud this year.
Eco Atlantic (LON:ECO), which is also partnering with French giant Total and Irish mid-cap Tullow oil in Guyana’s Orinduik license offshore, owns four licenses offshore Namibia, including a majority stake in the Cooper Block. ECO has a drill target ready at the Osprey Prospect, and is looking for another partner right now, with three more years on its license.
