Patent ID: 7360596

Claim:
A method for intensifying permeability of ground layers close to boreholes and of filter bodies and filter layers in an underground extraction area of water wells and other production wells comprising the steps of: (a) continuously pumping away liquid in an extraction area of a borehole by an underground pump; (b) continuously moving a pulse generator up and down in the extraction area to cause energy pulses generated by a surface pressure unit that is connected in leak-proof manner via a pressure line with the pulse generator being moved in the extraction area, the pressure line introducing a pressure line liquid in the pulse generator and said pressure unit exerting a high pressure on the pressure line liquid as a hydraulic pulse at a defined pressure and for a defined duration out of the pulse generator into the liquid to be extracted to successively impinge the liquid toward borehole walls and filter bodies and filter layers in the underground extraction area; (c) using seismic measurements to obtain a respective evaluation of an effect of each energy pulse; and (d) determining parameters of a following energy pulse according to the evaluation of a previous energy pulse.
