Geological structure and oil and gas potential of the Yenisei–Khatanga regional trough

Abstract

A model of the geological structure was constructed and the oil and gas potential prospects of the Yenisei-Khatanga regional trough were assessed. Construction of seismogeological sections, structural and tectonic maps, structural and tectonic analysis was carried out. It was concluded that the Neocomian clinoform complex, which contains about 90 % of oil, gas and condensate reserves in this region, is of the greatest interest in the study area in terms of searching for large oil accumulations. It should be expected that significant oil reservoirs localized in the Berriasian–Valanginian sand formations will be controlled by complex structural-lithological and lithological non-anticlinal traps.
