Abstract
An electro acoustic device and related method increase production capacity of wells that contain oil, gas and/or water. The electro acoustic device produces vibrations stimulating occurrences of mass transfer processes within the well. The resultant acoustic flow generated in porous media, produced by superposition of longitudinal and shear waves, is developed over a characteristic frequency threshold value specific to water, normal oil and heavy oil, with an acoustic energy density capable of establishing higher fluidity zones in the porous media, promoting mobility and recovery of desired fluid and formation damage reduction in a wellbore.
