| titleOfInvention | Method for controlling the viscosity of surfactant solutions |
| abstract | A method of recovering oil from a subterranean formation using an aqueous surfactant solution with a predetermined and controlled viscosity. The ability of the surfactant composition to impart viscosity to the aqueous solution is dependent upon the weight ratio of hydrocarbon oil in the composition to the surfactants in the composition. This oil/surfactant weight ratio must be maintained within the range of 0.05 to 0.40 to obtain a surfactant composition having the ability to impart a desired viscosity to its aqueous solution. The ratio can be maintained within this range and varied in value to change the viscosityimparting properties of the surfactant composition by adjusting the deoiling process during the manufacture of the surfactant composition or by adding hydrocarbon oil to the surfactant composition. |
