| Summary: | 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 (ρ). The AI, SI and ρ 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 (λ/μ) parameter is the best parameter for discriminating the potential sandstones. From the analysis result, <br />
<br />
<br />
<br />
obtained that low Lambda over Mu (λ/μ) 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. |
