The SandStoneDivert™ viscoelastic surfactant diverter system maintains viscosity up to 4 times as long as conventional systems, and features a surfactant-based gelling agent to enable enhanced acid stimulation treatments—without extra equipment requirements. After treatments are completed, the system’s viscosity can be reduced through exposure to high temperature, dilution in water, or contact with hydrocarbon liquids such as oil or solvent for easy cleanup and flowback. An internal breaker can also be used, if desired.
