Hydrogeochemical conditions of the Yarudey oil and gas condensate field are largely determined by its position within the elysion lithostatic water pressure system and the presence of a large number of faults in the base plate. In the article we explore the main features of the Neocomian and the Jurassic hydrogeological complexes of the field. Underground waters of the Mesozoic hydrogeological basin are characterized by chloride sodium ion-salt composition. They belong to the hydrocarbonate sodium type according to V. A. Sulin’s classification, mineralization is 7,0 g/l in the Neocomian complex and is 11,1 g/l in the Jurassic complex. The existence of complex hydrogeochemical conditions is confirmed by the nature of the change in the genetic sodiumchlorine coefficient (up to 1,4) and boron-bromine coefficients (up to 0,49).
