The structural style of the African Atlantic margin shows significant differences between the passive rifted Northwest African Atlantic Margin (offshore Senegal, Gambia, Guinea Bissau and Guinea) and...
Wide azimuth seismic surveying is firmly established as a key element in subsalt exploration and production in the Gulf of Mexico. The challenge now facing the industry is to further improve subsalt...
