The effect of ultrasonic waves on the phase behavior of a surfactant-brine-oil system

- Ultrasonic effect on phase behavior of surfactant-brine-oil was investigated.
- Solubilization parameter and optimal salinity changes under ultrasound were studied.
- Rotary mixer was put inside the ultrasonic bath.
- Short-period radiation of ultrasound yields more volume of microemulsion.
- Integrated ultrasound-surfactant flooding caused surfactant consumption to decrease.
