Annotation:
The authors of the article studied the influence of mineralization and residual water ionic composition of Talinskoye field on microstructural wettability and adsorbed oil. It is shown that these parameters depend on the concentration of sodium ions, chlorine ions and hydrocarbonate ions as well as on the pH factor.
