Geologicheskii Vestnik

The article deals with the processes occurring in regions with oil fields in the Southern Cis-Urals. Based on comprehensive long-term studies conducted by the authors, the changes occurring in the upper and lower hydrogeochemical floors are shown. Special attention is paid to finding out the causes and sources of pollution of fresh groundwater, for which the helium research method was used. The processes occurring in rocks under storage ponds are described. A close correlation was revealed between the mineralization of groundwater and the amount of precipitation in the region. It is shown that the restoration of hydrogeochemical conditions in the rocks occurs more than 50 years after the cessation of contamination in them.
