Abstract
Near wellbore formation damage is caused additional pressure drop around the wellbore and therefore decreased the oil or gas productivity of the well. The usual methods for removal of these damages are acidizing and hydraulic fracturing which have operational limitations in addition to high costs. Thus the researchers are motivated to find new methods and technologies specially the use of mechanical waves for well stimulation purposes.Ultrasonic waves have been extensively used in many industrial applications including clean devices, pipes and vessels. A clear extension of this usage is the removal of wellbore contaminants by exposing it to high-power ultrasonic waves. Although several...
