Abstract
A system for providing artificial lift to wellbore fluids having solid buildup removal capabilities includes a pump submerged in wellbore fluids and in fluid communication with a tubular member extending within a wellbore. The pump is oriented to selectively boost a pressure of the wellbore fluids traveling from the wellbore towards an earth's surface. A motor is located within the wellbore providing power to the pump. A seal assembly has a first side connected to the motor and a second side connected to the pump, wherein the pump, the motor and the seal assembly together form a submersible pump string. An ultrasonic device is connected to the submersible pump string and operable to produce pressure waves.
