Abstract

Abstract The study focused on interpretation of three-dimension (3D) seismic and suites of wireline log datasets, to construct and interpret models and facies analysis to assess the depositional structures, tectonic and stratigraphic unit’ settings. Challenges and uncertainties of low to moderate reservoir quality parameters attributed to limited understanding of depositional structures, tectonic and stratigraphic units had been identified in previous studies within the study area. From the study undertaken, the study area is structurally complex with compartments and flower structures. The stratigraphic interpretation, realized that sediments were highly intercalated (clay, silt, fine and coarse sands) majorly attributed to the short changes in climatic (wet and dry) conditions. It was further deduced that compartmentalization and intercalations of sediments had a very high effect on the reservoir rock properties which might affect the recovery of the available fluids.
