An ultrasonic technology for enhanced oil recovery is described. For the implementation of this technology, the equipment was specially developed, taking into account the working conditions. The criteria for selections of well candidates were developed. The technology has been tested in two different regions in different geological conditions. The results of these field tests indicate the high efficiency of the proposed technology. The success rate of the method reached 90% and the increase in oil production was in the range of 40% - 100%.
