This type of geochemical analysis allows to classify oil by chemical composition and provides additional information on productive pay zones and fields. To carry out the study, high-tech equipment and modern tools for data interpretation were applied. The data obtained can be used to deal with issues during field development and orient the areas of prospecting, evaluation and exploration work to promising oil and gas complexes. The article summarizes the results of geochemical studies of Embamunaigas fields and presents further vision for geological exploration.</p>geochemistrychromatography«oil fingerprinting»hydrocarbon migrationгеохимияхроматография«фингерпринтинг нефти»миграция углеводородов1.Peters K.E., Fowler M.G.
