Abstract
The purpose of this study was to identify the causes of the observed hydrogeochemical situation and the factors contributing to its formation within the Middle Jurassic hydrogeological complex in the western part of the West Siberian megabasin, using the Talinskoye oil field as an example. The research primarily involved constructing dependencies between mineralization (y) and various factors including porosity, reservoir pressure, modern and paleotemperature of the foundation, and depth of the foundation (x). The study evaluated the degree of connection between each parameter and mineralisation. The results showed that the initial hydrochemical state in the area is heterogeneous, with significant variations in mineralisation levels within a single reservoir. The closest dependencies have been revealed between mineralization and porosity of reservoir rocks (an inverse dependence), mineralization and reservoir pressure (a direct dependence). The practical significance of the study is justified by the need to understand the nature of the formation of the hydrogeochemical environment in order to preserve it, control changes, as well as solve issues related to the forecasting, preservation, and destruction of oil deposits.
