Abstract: A bottom hole assembly is configured with a drill bit section connected to a pulse generation section. The pulse generation section includes a relatively long external housing, the particular housing length being selected for the particular drilling location. The long external housing is positioned. closely adjacent to the borehole sidewalls to thereby create a high speed flow course between the external walls of the housing and the borehole sidewalls. The long external housing includes a valve cartridge assembly and optionally a shock sub decoupler. While in operation, the valve cartridge assembly continuously cycles and uses downhole pressure to thereby generate seismic signal pulses that propagate to geophones or other similar sensors on the surface. The amount of bypass allowed through the valve assembly is selectable in combination with the long external housing length and width to achieve the desired pulse characteristics.

Abstract: A cavitation chamber (26) is driven by a hydraulic driving system (22) in which acoustic pulses are generated by repeated water hammers. In the driving system (22) a liquid is pumped through a conduit. The flow of liquid through the conduit is periodically interrupted by a valve (42). A water hammer is created each time the valve (42) closes. Acoustic pulses produced by the water hammer propagate directly into a cavitation chamber (26) where they are reflected back and forth by acoustically reflective plates (72, 74). The cavitation chamber (26) may be applied to degas liquids, mix chemicals or slurries, or promote sono-chemical reactions. The design generates acoustic pulses efficiently. The acoustic pulses are coupled to the cavitation chamber (26) with minimal losses. The apparatus is rugged and inexpensive when compared to systems which incorporate electromechanical transducers.

Abstract: A method and apparatus are disclosed for generating intense acoustic pulses by means of the water hammer effect. The method involves generating a water hammer in a conduit (5) by suddenly interrupting a high velocity flow of fluid through the conduit (5). The kinetic energy of the fluid flowing in the conduit (5) is converted into a high pressure pulse which propagates along the conduit away from the point (7) where the fluid flow was interrupted. The high pressure pulse deforms the wall of the conduit (5) so as to radiate acoustic energy away from the conduit into a fluid medium (11) surrounding the conduit. The relative amount of energy dissipated in the form of mass flow in the surrounding fluid (11) and acoustic energy in the surrounding fluid (11) can be adjusted by changing the characteristics of the conduit wall. The direction in which acoustic energy is radiated into the fluid medium (11) surrounding the conduit (5) can be set by making the conduit wall asymmetrical or by bending the conduit (5). Embodiments of the invention for acoustic cleaning, viscosity reduction in fluids and acoustic sedimentation are disclosed.

Abstract: During a surge-pulsing operation in a borehole (e.g an oil-well undergoing remediation) liquid is stored under pressure upstream of a valve, and then released through the valve suddenly enough to create a seismic wave, which propagates into the formation around the borehole, and assists the surge-pulsing to improve the conductivity and liquid- injectability of the formation. The downhole valve achieves the rapid-opening requirement by virtue of its geometrical layout, as dictated by the strictures of the downhole environment.
