Disclosed herein is an autonomous and consistently active acoustic rehabilitation technology for wells, reservoirs, and extraction of natural resources using a borehole method. The invention can be used in oil, gas, mining, geological exploration industries, and in extraction technologies for oil and gas, including shale. It is especially useful for improvement of oil and gas output from wells and stimulation of production for maximizing recovery from reserves. The invention is applicable to areas including, but not limited to, well reserves using pumps, layer pressure supporting wells, and offshore-bed wells.
