The standard FSA using shale gouge ratio (SGR) algorithm is relying on two important parameters mainly fault throw and v-shale values. Yielding et al. (1997) algorithm is common used in FSA, which is used SGR terminology for estimating sealing capacity. The v-shale values are highly influenced by clay mineral composition particularly in carbonate rock with complex mineralogy. Therefore, v-shale need calculate using different petrophyscal method in order to have better sealing capacity distributions. The clay volume determination is using three types of methods, deterministic method using gamma ray log, non-linier Larionov method, and Multimineral model method. Generally, the SGR value using clay volume from deterministic analysis are greater than SGR value by using other clay volume. In this case, SGR values using clay volume from the Multimineral method provided more detailed models compare to other methods. The results of fault stability analysis showed that the NE-SW oriented fault tend to have movement and are reactivate with a slight increase in pore pressure. |
