The objective of this thesis is to study two Basins of the Gulf of Guinea (GoG),
namely the Dahomey and the Liberian Basins. These Basins are located in the northern
part of the GoG, where oil and gas exploration has significantly increased in the last 10
years or so. We proposed geological descriptions of these two Basins. The key
characteristics of the two models are the presence of channels and pinch-outs for depths
of between 1 km and 2 km (these values are rescaled for our numerical purposes to 600-
m and 700-m depths) and normal faults below 3 km (for our numerical purposes we use
1 km instead of 3 km). We showed that these models are consistent with the plate
tectonics of the region, and the types of rocks and ages of rocks in these areas.
Furthermore, we numerically generated seismic data for these two models and
depth-migrated them. We then interpreted the migrated images under the assumption
that the geologies are unknown. The conclusions of our interpretations are that we can
see clearly the fault systems in both models. However, our results suggest that seismic
interpretations of the channels and pinch-outs associated with the geology of the Dahomey and Liberian Basins will generally be difficult to identify. In these particular
cases, we missed a number of channels and pinch-outs in our interpretations. The limited
resolution of seismic images is the key reason for this misinterpretation.
