Namibe Basin - Angola/Namibia - 2020

ANG Namibe 2020 3D GeoStreamer (In Acquisition)

Namibe 2020 survey expands 3D coverage of a true frontier
Website Map for Survey Namibe 2020
The 2020 survey provides a 3D bridge between the 2014 Namibe 3D and the Angolan border into the Namibia. Fitting strategically into a large footprint of high quality 3D, the latest addition to the Namibe Basin brings a new understanding to the deeper water exploration concepts.
The prediction of reservoir presence and distribution maps indicate that the area contains variety of leads and prospects. The improvement of subsurface knowledge and understanding of the petroleum system play fairways will reduce risk for frontier exploration.
New regional 3D data and FWI velocity model building will better image structures, faults and traps. Compliant AVO attributes will significantly derisk deepwater exploration in the frontier Namibe Basin.
