<p>A hydrodynamic pulse tool and method for cleaning, stimulation and production enhancement of oil, gas and injection wells by propagating successive pressure waves through the wellbore and/or the producing/injecting formation in a directional or vectored manner. The tool comprises a resonance chamber defined by a generally cylindrical hollow tubular member adapted for connection to conventional coiled or jointed tubing, and at least one hydraulically driven pulse generator rotatably disposed within the resonance chamber. The hydraulic force of pressurized fluid pumped through the tool drives the rotation of the at least one pulse generator, which generates successive sequential hydraulic pressure pulses in a sequential, sequential offsetting and/or sequential reinforcing manner.</p> |
