A study of microfossils contained in the hydrocarbon fluids derived from four oil‐ and gas‐bearing formations in Western Siberia (of Paleozoic, Jurassic, Neocomian and Albian — Cenomanian ages) has shown the importance of processes of vertical migration in local hydrocarbon accumulations. These processes were found to be concentrated in regions of geological disturbance or intense fracturing of the reservoir rocks .
