Procedure

An ethanolamine-potassium viscoelastic surfactant suspension was generated by reacting 50 grams of stearic acid (95% purity; Sigma-Aldrich Chemicals) with 6.5 grams of ethanolamine and 40 grams of potassium carbonate in sufficient water to form one litre of the suspension. FIG. 8 shows the shear viscosity of the suspension for shear rates in the range from 0.1 s−1 to 100 s−1 at temperatures from 25 to 120° C. The surfactant suspension clarified on heating to give a clear, viscoelastic solution. At a temperature of 100° C., the surfactant solution achieved a viscosity of 100 cP at a shear rate of 100 s−1.
