Nano-scale structure of crude oil deposits on water-wet substrates: Dependence on aqueous phase and organic solvents
Wettability alteration of glass substrates due to displacement of the surrounding salt solution by crude oil, and its reversal via salt solution flooding, were investigated as a function of salt concentration and solution pH, and the sample preparation procedure. The resulting wettability states were analyzed by microscopy of the substrate-bound oil residues and contact angle goniometry. Atomic force microscopy of the flooded state under its salt solution showed partial coverage of the...[Show more]
