  • Vibrating system and method for use in sand control and formation stimulation in oil and gas recovery operations
    Publication number: 20110094732
    Abstract: A system and method for stimulating a formation penetrated by a wellbore and vibrating a device for supporting a gravel pack in the wellbore, according to which the build up of scale on the device is sensed and a corresponding signal is output. A tool is lowered into the wellbore, and includes a driver for driving an acoustic transducer coupled to the device for vibrating the device and stimulating the formation.

  • Method and apparatus for reducing a skin effect in a downhole environment
    Publication number: 20070256828
    Abstract: A method for reducing a skin effect in a downhole environment is provided, including the step of radiating vibrational waves at a wellbore wall such that the vibrational waves have at least one direction of greatest vibrational energy transfer directed toward the wall, thereby reducing the skin effect. An apparatus for reducing a skin effect in a downhole environment is also provided. The apparatus includes at least one vibrational wave source having at least one direction of greatest vibrational energy transfer, and a means for positioning the vibrational wave source proximate a wellbore wall.

  • Acoustic stimulation method with axial driver actuating moment arms on tines
    Patent number: 7216738
    Abstract: A method for generating acoustic waves, the method having the steps of: extending a tine from a support structure so that a proximal end of the tine is attached to the support structure and a distal end of the tine is uninhibited; positioning an oscillator so as to be supported by the support structure and to mechanically communicate with the tine; and oscillating the tine with the oscillator.

  • Acoustic stimulation tool with axial driver actuating moment arms on tines
    Patent number: 7213681
    Abstract: An apparatus for generating acoustic waves, the apparatus having: a support structure; two tines extending from the support structure so that proximal ends of the two tines are attached to the support structure so that distal ends of the two tines are positioned with standoffs relative to a dimension of the support structure and the distal ends of the two tines are uninhibited, wherein the two tines each comprise a moment arm; and an oscillator in mechanical communication with the two tines.
