For the first time a detailed analysis of the equilibrium-non-equilibrium state of ground waters of hydrocarbon occurrences in Arctic areas of the West Siberian megabasin based on physico-chemical modeling of equilibria in the «water-rock» revealed hydrogeochemical and thermodynamic conditions for the formation of authigenic minerals. For the first time equilibrated compositions of groundwaters and parameters of geochemical environment were identified, being a prerequisite for the mineral neoformations.
