Merging High-Resolution, Modern Deep-Water Data Sets with West Africa Subsurface Data to Validate Sand Body Geometry and Reservoir Facies Distribution

G-29 MERGING HIGH-RESOLUTION MODERN DEEP-WATER DATA SETS WITH WEST AFRICA SUBSURFACE DATA TO VALIDATE SAND BODY GEOMETRY AND RESERVOIR FACIES DISTRIBUTION Summary 1 Using modern deep-water marine geophysical and geological data sets as direct analogues for reservoir sand distribution in subsurface data sets is usually a frustrating activity. Sidescan sonar interpretation of the seafloor is best aided by ground-truthing of these (often spectacular) sonographs by sediment recovery using coring systems. However this is rarely undertaken routinely at the scale necessary to interpret the geometry and extent of sand bodies with recognizable geometry. Similarly in 3D seismic data sets high amplitudes
