Several variables influence the interfacial tensions (IFT) between an oil-rich phase and a surfactant-containing aqueous phase. During a surfactant flood, variations in surfactant concentration and salt concentration will occur due to mixing of the chemical slug with the preflush (or formation brine) and the polymer drive (rear mixing). Since these variables (and others) change during the progress of a flood, it is desirable to determine the impact of these changes on the IFT between the oil-rich and water-rich phases. In order to assess the importance of changes in these 2 key variables (surfactant concentration and salinity) on IFT, an X-Y plot may be constructed using values of each variable along the axes.
