Ecological and hydrogeological state of oil and gas bearing areas of the Barents and Kara seas shelf

The article deals with the ecological and hydrogeological conditions of the hydrogeological structures in the Barents-Kara shelf. Based on the hydrogeological and geoecological state of the Barents-Kara shelf, geoecological hazards were considered and distributed within the oil and gas regions of the West Siberian and East Barents oil and gas provinces. Preliminary geoecological zoning was performed and eco-geological zones were identified on the territory of first-order hydrogeological structures corresponding to the borders of several oil and gas-bearing regions of the East Barents and West Siberian oil and gas-bearing provinces. Thus, the current geoecological state of the Barents-Kara shelf was assessed. When drawing up the map of geoecological hazards, the hazards of technogenic origin caused by human economic activity and natural origin were taken into account, in particular, the influence of the neotectonic mode on the territory of the Barents-Kara shelf.
