Reservoir Characterization of the NKO Field, Onshore Niger Delta Basin Using Multi-Seismic Attribute Algorithms

The use of seismic attributes derived from seismic data has received considerable attention in reservoir characterization, especially in defining reservoir properties, and offers reliable solutions to the perceived reservoir problems within an old producing field (Ahaneku et al., 2016; Nwaezeapu et al., 2017; Obiadi et al., 2019). The seismic data also presents information related to stratigraphic features, rock property changes, and hydrocarbon accumulations. Seismic amplitudes which represent primarily contrast in elastic properties between individual layers contain information about lithology, porosity, pore fluid type, and saturation – information that cannot be gained without integrating seismic attributes, well log, and 3-D structural interpretation. The use of seismic attributes has proven to be one of the best techniques for quantitative seismic interpretation as the method can validate hydrocarbon anomalies and give valuable information during prospect evaluation, reservoir characterization, and production simulation (Taner et al., 1979).
