This paper includes an analysis of existing geological and geophysical data aimed at describing the characteristics of petroleum system elements. The main features of the sedimentation conditions of oil source rocks, reservoirs, and caps have been analyzed. The key hydrocarbon source zones in the territory of the Kazakhstan sector of the Caspian Sea have been determined. The correlation of existing wells to determine regional covers and main trends in reservoir sedimentation has been provided.</p>Kazakhstan sector of the Caspian Seapetroleum system elementsSouth Mangyshlak sedimentary basindepocentersgeological structureКаспий теңізінің қазақстандық секторымұнай-газ элементтеріОңтүстік Маңғышлақ шөгінді бассейнідепоцентрлергеологиялық құрылысказахстанский сектор Каспийского морянефтегазоносные элементыЮжно-Мангышлакский осадочный бассейндепоцентрыгеологическое строение1.Otchet po rezul'tatam rabot po I etapu issledovaniy Mezozoyskogo kompleksa kazakhstanskogo sektora Kaspiyskogo morya.
