Patent ID: 8881807

Claim:
A method for autonomously restoring the productivity of a well, comprising: submerging at least one wireless, self-sustaining, and self-governing acoustic device having on board power supply which provides a totality of the energy necessary for the acoustic device to operate independently into a wellbore, said at least one acoustic device comprising up to three acoustic units comprising phase locked acoustic emitters, at least one sensor, a control and processing unit, an independent power supply, and a means for movement along said wellbore, obtaining a reading of parametric data of a surrounding environment via said at least one sensor, processing said parametric reading by said control and processing unit of said generator, and initiating a corresponding mode of operation, said mode of operation including phase relations between said acoustic emitters, via said control and processing unit, comprising emitting an acoustic signal transmitting predominantly perpendicular to the well during a standard operation of said well, thus creating an acoustic vibration of said wellbore and a formation surrounding said wellbore due to a cumulative effect of phase locked acoustic waves for removal and fragmentation of clogging particles from said wellbore and formation surrounding said wellbore.
