One of inversion method that we have known is simultaneous inversion. Simultaneous inversion uses partial stack data with variations of angle (near, <br /> <br /> <br /> <br /> middle and far offset stack). The partial stack data will be inverted simultaneously using wavelets which were estimated from every stack. The results from <br /> <br /> <br /> <br /> simultaneous inversion are acoustic impedance (AI), shear impedance (SI) and density (&#961;). The AI, SI and &#961; are calculated to become reservoir petrophysics parameters such as Lambda-Rho, Mu-Rho and Lambda-over-Mu which are sensitive to lithology differences and fluid identifications. The results from simultaneous inversion and other calculated parameters were used to delineate <br /> <br /> <br /> <br /> sandstones. In this study, resulted that lambda over mu (&#955;/&#956;) parameter is the best parameter for discriminating the potential sandstones. From the analysis result, <br /> <br /> <br /> <br /> obtained that low Lambda over Mu (&#955;/&#956;) value related potential sandstone. Mu-rho parameter can distinguish where is the calcareous sandstone, sandstone and shale. Result analysis show the high value of mu-rho are <br /> <br /> <br /> <br /> appearance sandstone’s indicator. To understand lithology laterally, uses mapping and analysis both of <br /> <br /> <br /> <br /> parameters which obtained from slicing on horizon target.
