In northwest Germany, oil reservoirs are characterized by high-salinity brines with up to 23% TDS. For such salinity conditions, fatty alcohol derivatives with 4.5 ethene oxide (EO) units were found to lower the interfacial tension (IFT) drastically and to mobilize residual oil almost completely. Results obtained for the slug process indicated that variables such as IFT, surfactant concentration, flooding velocity, and pressure gradient influence the low-tension process in a combined manner. Oil produced in the oil bank showed alteration in properties, compared with the oil used to saturate the pore space.
