The analysis of existing geological and geophysical research as well as excavation works reveals that despite the prolonged search and exploration of the Productive Layer (PG) sediments in the South Caspian Basin (SCA), their hydrocarbon reserves remain insufficiently explored. Examination and consolidation of geological-geophysical data, drilling information, and the established 3D geological model indicate specific patterns in the distribution of oil and gas deposits within local elevations. These patterns are primarily influenced by tectonic processes. In the 3D geological modeling of the Palchig Pilpilesi deposit, the study accounted for tectonic processes occurring in the sedimentation basin of the sedimentary complex. This included the development of uplifts, their complication due to tectonic disturbances, and the impact of changes in the lithological composition and thickness of the horizons and layers constituting the productive layer section on the accumulation of hydrocarbon resources.
