Today, quantitative evaluation and interpretation of seismic data are of particular importance to better understand the reservoir characteristics of oil and gas fields. One of the important stages of evaluating a reservoir is describing the reservoir facies and distinguishing the different lithologies of the study area. Therefore, amplitude versus offset (AVO) analysis is one of the most important advanced methods for the analysis of geological facies, lithology, and fluid detection. In this study, simultaneous seismic inversion has been used in one of the oil fields in southern Iran on the Asmari formation. This study aims to separate the seismic facies using seismic attributes obtained from simultaneous seismic inversion, including acoustic impedance (IP), shear impedance (IS), and compression wave velocity to shear wave velocity ratio ( v_p/〖 v〗_s ). The results of this study demonstrated that if the quality of the data is good and the simultaneous inversion is performed with high accuracy, the analysis of pre-stack seismic attributes can lead to the separation of seismic facies with a high resolution.
