Most rock physics models were developed for specific reservoirs/conditions that only cover the variation of some of the reservoir parameters. Therefore, hybrid models have been formed to overcome at the limitations of individual models. However, the hybrid models still contain some of the original limitations that prevent the direct application of these models on the 3D and 4D seismic feasibility studies. This study employs five of the most well-known rock physics models to analyze their advantages and limitations. Then, an integrated model (Improved Shiri-Falahat (ISF)) is developed to cover the main parameters of a 4D seismic interpretation, including pressure and fluid saturation variation, mineralogy, porosity, and pore type. A set of sensitivity analyses are performed on the six models. The results identify the ISF method as the most sensitive model to variation of major reservoir static and dynamic properties. Furthermore, the six models are used to estimate compressional and shear velocity logs in an oil field. The results are compared with the measured sonic logs, where the ISF method provides the least RMS error, 8.11% for compressional and 7.26% for shear velocities, respectively.
