Shallow water Gabon 3D: focused processing images pre- and post-salt prospectivity

In 2017 Spectrum conducted a major 3D seismic acquisition programme of approximately 11,500 km² in shallow water offshore South Gabon (Figure 1). The project was carried out in close collaboration with the Gabonese Authorities (Direction Generale des Hydrocarbures; DGH) and was driven by renewed interest in a proven hydrocarbon province. Continuing exploration since the 1960s has proven all the key elements: source rock presence and maturity, reservoir presence and effectiveness, seal and oil charge into structural and combined structural-stratigraphic traps. Indeed, many oil fields, such as the Olowi Field, have been discovered and are producing in the onshore and nearshore.
