The tectonic structure of the northern part of the West Siberian oil-and-gas basin

A structural-tectonic zonation of the northern part of the West Siberian oil-and-gas basin, for the purpose of distinguishing the main types of positive structures promising for hydrocarbons, is made. The first revealed type is related to the zones of ultradeep depressions and represented by large inversion swells. The second one is represented by highs located in the side parts of ultradeep depressions, in the zones of tectonic steps and monoclines.
