In this study, prospects identified from a 3D seismic survey, in the Block W lease area, were investigated using a variety of seismic interpretation techniques, to de-risk the prospects and improve the overall geologic probabilities of success. The targets were marine shelf and margin clastic deposits of late Cretaceous age. The reservoir, charge and, critically, trap elements of the plays were analysed by combining novel seismic attribute products with interpretation and visualization techniques, AVO analyses, and conventional interpretations to obtain maximum information from the seismic data.
