| Disclosed is a method for restoring, maintaining, or increasing well productivity or reducing a water cut. The method comprises positioning an acoustic device in a well located within the geological formation and performing an acoustic treatment impacting a muddled zone in cycles comprising one or more manipulated waves of ultrasonic pressure on the muddled zone. The cycles comprising treatment comprise a Fourier transformation of a periodic function, wherein the transformation determines a rate at which an acoustic treatment pressure of each cycle rises from a value of zero to a maximum value. This rate is directly proportional to a force of an impact on the formation, and the greater the rate, the greater the impact. A cycle frequency is determined and designed based on particular formation parameters and particular treatment parameters obtained by sensors positioned on the acoustic device. The treatment is repeated until well productivity is restored. | ||||||
