In the journal “Geology, Geophysics and development of oil and gas fields”, 2019, № 8 (332) published an article by employees of LLC “INGEOSERVICE” on the topic “Characteristics of the seismic- geological model of the paleozoic-mesozoic complexes of the western part of the russian sector of the Barents sea shelf according to 3D seismic data”.
The paper presents the characteristics of the geological structure of the coal Lower Permian, Upper Permian-Triassic, Lower-Middle Jurassic (Aalen-Bayos), Middle Jurassic (Bat Callovian), Upper Jurassic, Neocomian and Aptian-Albian Cenomanian complexes. A brief description of the model of their sedimentation and the established identifi ed petroleum potential is given. Based on the comprehensive analysis of the seismic data, with account of some specifi c features of the complexes, promising areas were identifi ed. Due to the greater disturbance of the explored territory by disjunctive tectonics, it is concluded that it can possibly have a negative effect on the oil and gas potential of the lower-lying complexes (destruction of hydrocarbon deposits). On the other hand, due to the observed processes of hydrocarbons vertical migration because of tectonic disturbances, the formation of secondary hydrocarbon deposits in the overlying sediments is possible.
