HYDROGEOLOGICAL CONDITIONS FOR THE PRESENCE OF OIL AND GAS IN THE WESTERN SEGMENT OF THE YENISEI-KHATANGA REGIONAL TROUGH
This article describes the petroleum potential of the Mesozoic deposits in the western segment of the Yenisei-Khatanga regional trough, as assessed from the hydrogeological data. The study area includes the Krasnoyarskregion and neighbouring zones of the Yamal-Nenets Autonomous District (Fig. 1). In...

This article describes the petroleum potential of the Mesozoic deposits in the western segment of the Yenisei-Khatanga regional trough, as assessed from the hydrogeological data.

In tectonic terms, it is confined to the Yenisei-Khatanga regional trough and separates the Taimyr system of tectonic dislocations from the Siberian Platform [Kontorovich, 2011; Pronkin et al., 2012].
