Schemes of oil geopetroleum zoning of Russian and Kazakhstan sectors of the Caspian Petroleum Province were previously proposed to optimize quantitative assessment of predicted oil and gas resources. Since geological and geope-troleum boundaries do not coincide with those state and administrative, and the Caspian Petroleum Province is a single petroleum basin, a unified, a consistent scheme of geopetroleum zoning of the subsalt megasequence is proposed. The suggested zoning option is based on the basin modelling methodological approaches and involves the assessment of the extent to which the oil and gas accumulation processes are supported by expulsed, remaining liquid and gaseous hydro-carbons. The modern structural plan of the regional salt-bearing Kungurian Top underlies oil and gas accumulation area delineation in keeping with the subsalt deposits. There are two oil and gas bearing regions identified, namely: North Caspian (Volgogradsky-Orenburgsky) and South Caspian (Astrakhansky-Aktyubinsky) with the oil and gas bearing areas within them.
