A regional transect running through acreages of several companies has been studied to provide a seismic-sequence stratigraphic analysis which would form a model for studying other transects in the Niger delta. The study also refined the interpretation of depositional history, environments and formed a basis for corroborating work done on lithology distribution in the eastern part of the Niger delta.

The study is based on interpretation of twelve key wells: KI-1, KR-1, KB-1, KA-1, Tubu-1, Asaramatoru-1, Yomene-1, Korokoro-1, Afam-1, Ngboko-1, Oza-1 and Obuzo-1 and involved mostly 3D seismic interpretation, well log data analysis, stacking patterns, biofacies and biostratigraphic data analysis tied to seismic

The model suggests the overall stacking pattern of depositional elements is the sedimentary fill of successive megastructures. Also downward shifts of facies suggests the possibility of reservoirs at depths below current well penetrations.
