The Study of Reservoir Characterization of Sarvak Formation with Seismic Inversion and Integrating Seismic Attributes in an Oil Field in Southwest of Iran

Porosity is one of the most important parameters in reservoir characterization which allows the specialists to design and manage، effectively، the process of oil and gas fields development. Using the core samples and well logs are two normal ways to porosity and permeability evaluation but the results are valid just in a vicinity around the well،، By utilizing 3D seismic data، combination with the core and well log data، will allow to predict reservoir properties through the whole reservoir. This paper is based on 3D seismic data interpretation and the result of well logs data analysis. Also By using seismic Inversion on 3D seismic data and Integration seismic Attribute، reservoir characterization of Sarvak Formation in an oil field in SW of Iran has been studied. Based on the results، facies changes were recognized in the sediment، so the porosity varies in different areas of this field. However porosity significantly increased in central parts of Sarvak Formation in the study area.
