Abstract

Evaluating fault seals forms an important component of hydrocarbon exploration, production, and reservoir management. However, most of the fault seal analysis workflow and theory is developed for normal fault system. In the case of oblique convergent strike-slip fault deformation, the movement of the block will involve both vertical and horizontal components. Therefore, additional evaluation need to be done for using standard fault seal analysis workflow. This study demonstrated results of fault seal analysis study which show the important relationship between fault geometries, distributions and characteristic in term of sealing and leaking with the reservoir compartmentalization in the Jambi Merang Area, South Sumatra Basin. The results of study reveal several major concerns in particular related to the faulting history due to the deformation history. Deformation history of the study area is dominated by oblique convergent strike-slip fault which means appearance slip or throw on most faults are not total movement history. Consequently, the results of calculation should consider as minimum of fault sealing capacity. Fault seal is largely controlled by v-shale distributions rather than by throw as demonstrated by faults having small throws. This result suggested that distributions of good quality sand reservoir become the main control of fault sealing capacity.
