“…Previous studies conducted in various rift basins located offshore China, such as the Zhu I subbasin of the PRMB [74], the Xihu subbasin of the East China Sea Shelf Basin [10], and the Qinan area [27,46], Tangbei area [75], and Bozhong subbasin of the Bohai Bay Basin [76], have indicated similar hydrocarbon migration and accumulation patterns controlled by fault seals, albeit with some differences. Besides China, the North Sea also exhibits a pattern of hydrocarbon migration, accumulation, and distribution under the control of fault sealing [21,23,42].…”

Faults play a pivotal role in controlling fluid migration and retention within sedimentary basins, particularly in the context of fault-bound hydrocarbon reservoirs. Assessing the stability and sealing capabilities of faults enhances our comprehension of these systems and aids in the identification of pathways for fluid migration. In this study, we focus on a series of fault-bound hydrocarbon accumulations located in the southern Wenchang A subbasin within the Pearl River Mouth Basin. We emphasize the significant influence of faults in governing the processes of hydrocarbon migration and accumulation. By leveraging 3D seismic data and well information, we have assessed the sealing potential of ten faults that either currently retain hydrocarbon columns or have the potential to do so. Our analysis reveals that even faults with a relatively low Shale Gouge Ratio (as low as 15%) can effectively support substantial column heights. Taking into account factors, such as the source rock maturity, fault activity, geometry, sealing potential, and the distribution of hydrocarbon accumulations, we have formulated a conceptual model for hydrocarbon migration and accumulation within the study area. This model underscores potential fluid traps within the rift basin, shedding light on the complex dynamics of hydrocarbon movement in this region.
