ANG Block 1/14 3D GeoStreamer

New GeoStreamer data in Angola Lower Congo Basin
Website Map for Survey AGO-PGS-Block 1/14
The survey is designed to produce data of superior resolution to increase understanding of the prolific Lower Congo Basin. The Block 1/14 survey provides the first modern broadband 3D data in the area.
Exploration targets in the Lower Congo Basin are found in several stratigraphic intervals. The post-salt section contains the proven Miocene play with numerous producing oil fields. The Upper Cretaceous and presalt section remains relatively underexplored with multiple opportunities identified.
High density 3D GeoStreamer data improves understanding of the geological framework and remaining hydrocarbon potential. GeoStreamer multi-sensor technology provides subsurface images of greater clarity, accuracy and reliability ro reduce exploration risk.
