Recently acquired reflection seismic data on the Gabon margin reveals a well-developed Paleogene and Cretaceous marine section that correlates well with principal second- and third-order eustatic sedimentation cycles established for the South Atlantic basin. Key biostratigraphic data and wells aid in controlling identification and correlation of sequence boundaries and their component systems tracts. Application of sequence stratigraphic concepts delineate play elements between widely spaced exploration tests. Slope fan-basin floor fan systems tracts of the Ogouee delta and Albian carbonate boudin structures similar to those evaluated in offshore Brazil by exploration tests are identified. A continental pre-salt Aptian-Neocomian section exists beneath the shelf and slope that has been little tested to date in the offshore. Significant exploration opportunities within the Upper Cretaceous/Paleogene and Aptian pre-salt sections exist on the Gabon slope and remain to be tested.
