https://www.intechopen.com/chapters/84648 In recent years, ultrasonic technology has played an important role in the development of oil fields, which has improved oil recovery. Ultrasonic waves are a very suitable method for producing oil at a low cost and without environmental pollution. The reservoir is treated using high-power sonication, which affects the physical properties of the oil and thus improves the permeability, which increases the oil recovery. The ultrasonic technique is also used to reduce the damage of the formation in the areas near the well, and this reduces the penetration of mud and sediments. However, ultrasonic waves remove oil barriers to the well and improve oil recovery for a long time. In this chapter, recent developments and laboratory and field results of ultrasonic waves in improving oil recovery will be discussed, and it will be shown that these waves are highly efficient.
