The paper discusses the historical aspects of hydrocarbons origin, considers various facts in favor of organic and abiogenic hypotheses. On the basis of 3D seismic exploration within the limits of the Western Siberia, the Barents Sea and the Kara Sea, there presented images that indirectly confirm the participation of one or other hypothesis in the processes of oil generation. The results of 3D seismic survey data, which was performed in the Barents-Kara region, the Western Siberia oil and gas potential province, convincingly show the large scale of the manifested fluid dynamic model of hydrocarbons (HC) ascending migration from the depths of the Earth. It is shown that the so-called fluid dynamic channels are associated with the rift genesis stage and the formation of stress zones, to which the channels of destruction and fluid conductivity of the Earth’s assets are confined. The study of seismic artifacts allows one to come up with an explanation of the nature of the formation of such widespread natural phenomena as the anomalous structure of the Bazhenov formation, the distribution of abnormally high reservoir pressures (AHRP), the patterns of hydrocarbon deposits (HC) distribution along the sedimentary cover section and others.
