abstract = "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. In this paper, a mathematical model for ultrasonic
propagation through the porous medium around the wellbore is presented. The equations of wave propagation are written in a cylindrical coordinate according to Biot theory and the induced stress in the rock are calculated at each point using finite difference approach Comparison of imposed
local stresses with adhesion forces between scales and rock, the properties of ultrasonic transducer, such as frequency and amplitude, which are needed for breaking adhesion forces, can be determined. The results show that the wave with frequency about 25 kHz and amplitude about 50 microns
will apply up to 107 Pa radial stress to the adhesion surface between deposits and rock and has ability to clean the pores, if the required stress for separation of scales is smaller than this applied stress.",
