This article shows the geochemical studies of associated produced reservoir water of the Bobrikovian horizon by the area of research at one of the deposits of the Republic of Tatarstan. The horizon is characterized by terrigenous rocks, which in turn is underlain by a massive carbonate reservoir. Quite a lot of producing wells work for it, and also, in view of reserves development, a system for maintaining reservoir pressure has been introduced. Based on the composition of the produced water, maps of the distribution of geochemical parameters over the area are constructed. 3 zones according to the concentration of elements were identified. In the region with maximum oil saturation, the water composition is characteristic of the waters of the Bobrikovian horizon. And in the region with the most depleted reserves and greater water cut, water is most likely to flow from the underlying Tournaisian carbonate strata, which is reflected in a change in composition. Also, tracer studies were conducted to establish flows in the deposits. The work shows an integrated approach to the study of real flows in deposits, based on the composition of produced formation water, and can be used to understand the processes occurring in the reservoir and refine hydrodynamic models, since it is a direct method of study.
