The processes of oil dissolution in water with different mineralization, pH and time of "mineralized water-oil" contact, were examined in present work. It is shown, that a maximum quantity of oil components extracts from water in the conditions of a weak mineralization and the acid medium. It is established, that the group composition of oil hydrocarbons dissolved in water is influenced by contact time on intersection of "mineralized water-oil" mixture. The growth of quantity of aromatic compounds passed to water from light oil along with increasing of contact time indicates formation of steady disperse system in a solution. For heavy oil the small content of aromatic hydrocarbons is connected with presence of a considerable quantity of high-molecular compounds which form unsTable disperse system in a solution. The behavior of relative content of oxygenic compounds testifies to reversibility for process of light oil components dissolution along with contact time increasing, whereas increasing of their concentration in "mineralized water-oil" mixture is marked for heavy oil.
