Deposits of lacustrine hydrocarbons and geoecological aspects related to their genesis

Abstract

It is shown that hydrocarbon deposits associated with fossil lacustrine complexes represent a separate genetic group of deposits that differ in terms of a complex of geological, geochemical and geoecological features. The mechanisms of accumulation of sours rocks in lacustrine basins of different hydrological typeare presented. It was established that the lacustrine genesis oil has a better chemical composition compared to liquid hydrocarbons of marine genesis. However, their extraction requires additional economic and environmental costs due to complex geological conditions
