| titleOfInvention | Waterflooding employing thickened surfactant solutions |
| abstract | Waterflooding process for the recovery of oil from a subterranean formation in which at least a portion of the injected water is thickened by the addition of a mixture of sulfonated polyethoxylated aliphatic alcohol surfactants. The thickened water has a salinity within the range of 5-18 percent. The mixture of sulfonated polyethoxylated aliphatic alcohols has an HLB within the range of 10.0-14.0 and the lipophilic base of the surfactant mixture contains an average of from 16 to 20 carbon atoms. The surfactant mixture incareases the viscosity of the water to a value greater than viscosity achieved through the addition of only one of the surfactant components. |
