In oil industry results of AVO inversion can be used in extracting Lamas parameters and computing elastic impedance for identification of elastic parameters, and discrimination of lithologies and fluid content of reservoir. Cross plot techniques that compare two or more different attributes can be applicable for this object. In this study, we discuss results of AVO inversion curried out in a sandstone reservoir of an oil field in Persian Gulf. We have used 3D prestack seismic data, and log data including shear wave logs of a well in oil part of the reservoir to calibrate with real data. The AVO behavior of the top of reservoir belongs to class IV of AVO anomalies. Extracting Lamas parameters and elastic impedance from seismic data and also cross-plot of different parameters have been useful for discrimination of different lithologies and fluid content.
