Characteristics of groundwater in the Mesozoic hydrogeological basin at the fields of the Yamalo-Nenets oil and gas producing region

The chemical composition of reservoir water in the Mesozoic hydrogeological basin is closely related to the conditions of sedimentation, tectonic development, and formation of hydrocarbon deposits. This water composition in combination with other geological parameters makes it possible to predict the presence of industrial accumulations at oil and gas fields. Investigated groundwater plays an important role in the operation of oil and gas fields in the territory of the Yamalo-Nenets oil and gas producing region.
