Tectonic model of the Eastern part of the Svalbard plate in the Barents Sea and its relationship with hydrocarbon migration indicators (article).

The paper presents the new seismic data on the specific features of the Svalbard Plate geological structure within the Russian part of the Barents Sea region. The Svalbard plate has an Archean basement age, which corresponds to the Grenville orogenic cycle (approximately 1250…980 million years). The close link is established between the tectonic model of sedimentary complexes formation (Upper Permian-Triassic, Jurassic (Aalenian-Bajocian, Bathonian-Callovian stages), of Neocomian and Aptian-Albian-Cenomanian stages) and hydrocarbons fluid migration manifestations. Seismic process indicators of the vertical hydrocarbons migration have been studied according to the 2D and 3D seismic data.

Keywords: waters of the Barents Sea; sedimentary complex; seismic section; reflection horizon; seismic attributes; fluid migration.
