Ultrasonic assisted water flooding

Waterflooding being the most frequently used improved oil recovery methods fails to produce more than 30% of OOIP due to high viscosity of oil and/or high interfacial tension. Therefore chemicals or miscible flooding methods are required to improve the recovery of waterflooding. Another alternative...
