Procedure

A mixed ethanolamine-potassium viscoelastic surfactant suspension was generated by adding 40 grams of tallow acid (product T1 from Procter and Gamble) to 6.5 grams of ethanolamine and 40 grams of potassium carbonate in sufficient water to yield one litre of product. FIG. 6 shows the shear viscosity of the surfactant suspension for shear rates in the range from 0.1 s−1 to 100 s−1 at temperatures from 25 to 100° C. The viscosity of the suspension increased on heating up to 60° C. as the surfactant dissolved in the water to form a clear solution. A further increase in the temperature of the surfactant solution resulted in a decrease in the viscosity of the clear surfactant solution and an approach to Newtonian rheology.
