  • Patent number: 8061421
    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.
    Type: Grant
    Filed: September 18, 2006
    Date of Patent: November 22, 2011
    Assignee: Wavefront Energy & Environmental Services Inc.

  • Patent number: 6405797
    Abstract: For extracting a liquid (such as oil) from a porous medium, the liquid is subjected to pulses that propagate through the liquid flowing through the pores of the medium. The pulses cause momentary surges in the velocity of the liquid, which keeps the pores open. The pulses can be generated in the production well, or in a separate excitation well. If the pulses travel with the liquid, the velocity of travel of the liquid through the pores can be increased. The solid matrix is kept stationary, and the pulses move through the liquid. The pulses in the liquid can be generated directly in the liquid, or indirectly in the liquid via a localized area of the solid matrix.
