Acoustic well recovery method and device

An electro acoustic device for increasing the production capacity of wells that contain oil, gas and/or water by stimulating mass transference processes within said wells, said electro acoustic device comprising:

• an electro acoustic transducer;
• and
• a sonotrode having a tubular geometric shape with an irradiation surface developed along an axis of a well, wherein dimensions of said tubular geometric shape are determined by operating conditions under resonance parameters of longitudinal and radial vibrations in a natural resonance frequency of said electro acoustic transducer, said sonotrode comprising a first end having the shape of a horn and a second end having the shape of a hemisphere with an inner diameter one-half the diameter of said tubular geometric shape;
• wherein said electro acoustic device is configured to introduce mechanical vibrations in a well bore region along said axis of said well, producing shear vibrations in the well bore region due to displacement of phase of said mechanical vibrations, achieving alternately tension and pressure by superposition of longitudinal and shear waves.
