Viscoelastic surfactants have been used extensively in the field. They have the ability to form long rod-like micelles with an increase in p H and calcium concentration, which results in increasing the viscosity and elasticity of partially spent acids. There is ongoing debate in the industry about whether the gel generated by these surfactants causes formation damage,
