Bodine, A G

A method is described for stimulating the flow of effluent from a formation surrounding a well casing having perforations formed therein for passing the effluent into the casing comprising the steps of: lowering a positive displacement moyno sonic oscillator into the well casing to the region of the formation so it is suspended freely therein, feeding a stream of liquid down the well casing to the oscillator so as to rotatably drive the oscillator to effect the radiation of gyratory quadrature sonic vibrational energy therefrom, discharging the liquid from the oscillator into the well casing, adjusting the rate at which the stream of fluid is fed to the oscillator to bring the vibrational output of the oscillator to a predetermined frequency and to establish and maintain the substantial hydrostatic head in the region of the oscillator, and continuing to feed the liquid to the oscillator until the formation is permeated as indicated by a substantial lowering of the level of the hydrostatic head.
