Application of Seismic Inversion in Estimating Reservoir Petrophysical Properties: Case Study of Jay field of Niger Delta

The conventional approach in reservoir characterization uses an extrapolation of petrophysical properties calculated from well logs determining the entire field volume. This technique fails to acknowledge/ factor heterogeneity a reservoir, and consequently leads errors capacity quantification. research work employs deterministic seismic inversion each sand. First, sand was identified intervals low gamma-ray value with corresponding high resistivity log value. A synthetic seismogram generated tie data identify events that correspond sands. done by convolving reflectivity series, derived approximated Zeoppritz zero-phase wavelet using seismic. Acoustic impedance were analyzed proved have strong correlation. then constrained determined parameters well, it used generating petrophysics base model inversion. Deterministic carried out be able determine such as porosity, volume shale, water saturation are associated fluids Jay-field shallow offshore Niger Delta.
