Purpose.To study the formation peculiarities of the physical and chemical composition of highly mineralized edge waters in oil and gas fields.
Methods. The correlation relationships between the macroions of the edge water were established by calculation of the Pearson correlation coefficient. In order to determine the complex influence of the concentrations of several ions on the individual ion concentration, the methodology of multiple correlation-regression analysis was used.
Findings. The empirical dependences between concentrations of individual ions in highly mineralized edge waters were obtained as a result of the study.
Originality. The dependences between the general water mineralization and content of macroions, as well as the complex influence of several ions on the individual ion concentration, were determined.
Practical implications. The established dependences can be used for carrying out laboratory analyses of edge water.
