Patent ID: 7059403

Claim:
A method of stimulating the occurrence of mass transfer processes which increase production capacity of wells containing oil, gas and/or water, comprising: (a) introducing mechanical vibrations into a well bore region of a well to produce shear vibrations in said well bore region due to phase displacement of mechanical vibrations produced along an axis of said well; and (b) achieving alternately tension and pressure within said well by superposition of longitudinal and shear waves in porous media irradiated thereby and within said well, thereby stimulating the occurrences of mass transference processes within said well; wherein said superposition of longitudinal and shear waves provides an acoustic flow in the well bore region with speed U f and wavelength λ/4, and wherein a displacement frequency of an acoustic field providing said acoustic flow is at least a value corresponding to a characteristic frequency calculated for said porous media to be irradiated.
