Abstract
The article discusses the continental shelf of the East Siberian Sea for forecasting promising oil and gas objects using basin modeling. A structural-tectonic model has been built for four main sedimentary complexes: Pre-Aptian, Upper
Cretaceous, Paleogene, Neogene-Quaternary. On the territory of the East Siberian Sea, at the stage of forecasting oil and gas fields, two oil and gas source strata (NGMT) were identified: Aptian-Upper Cretaceous and Paleogene. Areas of accumulation of hydrocarbons are shown and promising oil and gas complexes are identified: Upper Cretaceous, Paleogene, Neogene.
Materials and methods
The presented work is based on the results of generalization of geological exploration works using modern technologies of basin analysis and numerical basin modeling. To form a model of the structural-tectonic frame of the sedimentary basins of the East Siberian Sea, structural constructions of a scale of 1:1 000 000 were used, performed by specialists of «MAGE» in 2013. The modeling strategy was determined by the peculiarities of the geological structure and evolution of sedimentary basins, as well as the quality of the available geological, geophysical and geochemical information.
