title: Genetic Types of Crude Oil in the Eastern Part of the Crimea–Caucasus Area
abstract: The paper presents data on 48 samples of crude oil and oil shows from oil fields and surface oil seeps in the Krasnodar Territory, Crimea, and the Russian part of the Black Sea. The oil samples were analyzed for isotope and molecular composition. According to the results, all crude oil samples were classified into three genetic types (Akhtyrsky, Sladkovsky, and Nikolaevsky), which differ in molecular and isotope composition and were derived from different types of source organic matter.
