Laboratory evaluation of the effects of additives and pH on the thermorheological behavior of a viscoelastic zwitterionic surfactant used in acid stimulation

This paper examined a new class of zwitterionic viscoelastic surfactant (VES) used to increase the efficiency of the acid stimulation process. The effects of CaCl2 salt and methanol additives on the rheological properties of these systems were examined over a wide range of parameters. The behavior o...
