The article examines the issue of improving the efficiency of geological exploration of oil and gas fields of the Cuu Long Basin in the territorial waters of Vietnam. The relevance of the study is determined by the need to reduce uncertainties in assessing the structure of sedimentary strata and to identify prospective zones. The main objective of the research is to validate a comprehensive approach to modeling the hydrocarbon system, which includes sequential stratigraphic modeling, analysis of tectonic history, and assessment of fault conductivity. The study employs methods of facies analysis, petroleum system analysis, and evaluation of reservoir properties of rocks. Special attention is paid to assessing clay content in faults and their role in hydrocarbon accumulation formation. The integrated modeling methodology that accounts for sedimentation patterns, tectonic evolution of the territory and fault characteristics demonstrated high reliability at existing sites. The practical significance of the work lies in enhancing the accuracy of prospective area prediction through an integrated modeling approach. Obtained results enable to optimize geological exploration planning and risk reduction in searching new hydrocarbon deposits. Promising future research directions include automation of sequential stratigraphic modeling stages to reduce time costs and implement the methodology in routine exploration practice.
