| Abstract | ||
| The direct way to access the petrophysical property of hydrocarbon reservoir is based on well data but due to its high cost, the seismic data has been used to obtain these parameters. For this purpose, many different methods are available and each has its own advantages and limitations. From these methods the seismic inversion is the best tool to study the reservoir characterization. The outcome of the seismic inversion is the transformation of seismic reflection data to pseudo-impedance logs at each CMP. It is therefore, the seismic inversion results facilitate better estimations of reservoir properties such as porosity. In this study the results of two different post-stack inversion methods on seismic data will compared. These are sparse-spike and model-based methods. These results were used for acoustic impedance construction based on 2D seismic data in the Saraje Gas Field. By using this model and creation of linear regression the estimated porosity model has been achieved. | ||
