This work is dedicated to the analysis of the geological structure and the hydrocarbon potential of the Aptian deposits of the productive formations PK21-22 within the Pokurskaya Formation in the N field of the West Siberian oil and gas province. Through an examination of the sediments in formations PK21-1, PK22-1, PK22-2-0, and PK22-2, a reconstruction of the sedimentation conditions during the Early Aptian period was conducted, complemented by seismic data interpretation and attribute analysis. Detailed sedimentological analysis of core samples, alongside electrofacies analysis of well logs, was also performed. Based on these studies, a conceptual model of formation sediments was developed. As a result of the integration of all research findings, a facies zone distribution map was created. This map illustrates the spatial distribution of sedimentary environments and highlights prospective areas within the field. The study concludes with this facies zone map, providing a foundational understanding of the sedimentary and structural patterns of the region.
