Delhi Field is located in northeastern Louisiana. The reservoir is the Holt-Bryant zone that consists of Upper Cretaceous (Tuscaloosa) and Lower Cretaceous (Paluxy) sandstones. Currently, the field is undergoing a tertiary CO2 flood of the Holt-Bryant zone for enhanced oil recovery. To better understand the complexity of the reservoir, seismic and well log data were used to determine petrophysical properties within the reservoir. Correlations were established between: density and gamma ray; P-impedance and porosity. Pre-stack, model-based inversion was performed on the seismic data to obtain volumes of density and P-impedance. At the same time, synthetic seismic traces were created by changing the petrophysical properties, and correlations found previously were examined again.
