Can a novel 3D template improve lithology and fluid discrimination in seismic interpretation? This paper introduces a prism-shaped rock physics template (P-RPT) to enhance the efficiency and accuracy of lithology and fluid identification using well-log and seismic data. The P-RPT integrates conventional rock physics models, ternary charts, and binary charts into a three-dimensional framework. This novel template facilitates fluid discrimination and lithology identification by incorporating P- and S-wave velocity ratios, Lambda-Mu parameters, acoustic impedance, Lamé parameters, and porosity. Validation on blind data sets from diverse reservoirs demonstrates the P-RPT's reliability and user-friendliness. The P-RPT enables comprehensive data interpretation on a single chart, streamlining seismic analysis and improving the detection of fluid types and lithology. The authors provide a detailed methodology for implementing and updating the P-RPT, promoting its localization and adaptation for various geological regions. This innovative approach offers a valuable tool for seismic interpretation and reservoir characterization.
