Abstract: The use of seismic inversion attributes in reservoir characterization is generally becoming an important factor in integrated reservoir studies, its uses has clearly revolutionize the ways and manners reservoir interpretation is been performed. This paper demonstrates the robustness and advantages of integrating/use of seismic inversion attributes in discriminating the fluid contents and lithology of the reservoir of the case study area. The study involves crossplots analysis of different extracted attributes and their sensitivities to reservoir fluid contents and lithology respectively. The analysis shows that Lambda-Rho () attribute is more robust in fluid and lithology discrimination than Mu-Rho () attribute irrespective of the petrophysical parameters of the field considered. The values seismic inversion attributes added to the study includes improved and robust fluid and lithology discrimination
