Rock physics enhanced strati-structural interpretation of the "Wuzuzo Field", onshore Niger Delta, Nigeria

Abstract Rock physics enhanced seismic strati-structural interpretation of the Wuzozo Field revealed two genetic units with the reservoir sands interpreted as channel fill deposits belonging to the Low Stand Systems (LST) and Trangressive Systems Tracts (TST) respectively. Estimated effective bulk moduli of the field revealed values between 23.55-36.74GPa for sand bodies while the results of the rock physics modeling revealed that the elastic moduli increases as porosity values decrease. Evaluation of the reservoir properties indicated that the pay zones are high-quality sands owing to their high effective porosities and net-to-gross ratio. In conclusion, the integration of rock physics with seismic stratigraphy has proved to be an invaluable tool for identifying prospective pay zones, especially at deeper subsurface intervals.
