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 distribut...

The article describes the results of laboratory measurements of the micro-component composition of the produced oil and the mathematical processing of the obtained values in one of the fields of the Republic of Tatarstan. Vereiskian and Bashkirian horizons were studied, which are quite widespread in the Republic and surrounding areas. The studied horizons lay one above the other in close proximity to each other. The Bashkirian deposits are a massive reservoir, while the Vereiskian deposits have the form of a layer...
