Composition of Oil and Layer Waters and it’s Impact on the Ecology of the Caspian Sea

Abstract

The article presents a brief analysis in the field of oil chemistry: the study of microelements in oils and formation (layer) waters, as well as environmental problems arising from offshore oil and gas production. The impact of oil and gas production on the ecology of the Caspian is shown; it was noted that from an ecological point of view, the study of the microelement composition of processed oil is very important for identifying sources of environmental pollution by oil, because microelements are present in all oil fractions, starting with gasoline ones, and their amount, as a rule, increases with an increase in the boiling point of the fraction, reaching a maximum in the residues.
