| Abstract | ||||
| Many seismic interpretation techniques for reservoir characterization are depended on acoustic and shear impedances but in some cases the results of these impedances are not satisfied. Poisson impedance (PI) could be an effective attribute to solve the problems of lower contrast between sand and shale. In this study, Poisson impedance attribute is calculated based on acoustic and shear impedances crossplot. The calculated Poisson impedance logs are matched very well with shale volume log in the correlation chart between them. Then Poisson impedance volume is generated by using EEI inversion technique. Analysis the inverted Poisson impedance cross sections and extraction the amplitude maps represents the variation of reservoir sand and shale within the sienna channel that indicate PI is very promising attribute for sandstone reservoir characterization. | ||||
