Quantifying anomalies detected on seismic-generated attributes is critical to evaluate carbonate reservoir heterogeneities prior to planning and designing CO2 enhanced oil recovery operations. In this study, facies-based pre-stack inversion method is applied to a 3D compressional wave seismic survey to characterize the Ordovician Red River U4 dolomitic reservoir. The facies-based inversion technique is able to delineate reservoir and non-reservoir facies and quantify porosity from inverted elastic volumes and the developed rock physics model.
