Groundwater geology of the western Siberian craton (implications for petroleum exploration)

According to the suggested model of groundwater stratigraphy obtained on the basis of geological and groundwater data, the sedimentary cover of the western Siberian craton includes the suprasalt, salt, and subsalt groundwater units subdivided into regional and subregional reservoirs. It has been found reasonable to carry out special groundwater studies, either before or concurrently with petroleum exploration, in order to ensure supply of drinking, household, and technological waters to meet the demand of oil and gas production and to make groundwater available for oil-well pressure maintaining systems and for underground burial of waste waters.
