Bryan L. Gonsoulin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Nuclear magnetic resonance apparatus and method having toroidal antenna windings
    Patent number: 6703833
    Abstract: An NMR apparatus includes permanent magnets oppositely polarized in the axial direction and suitably arranged along the axis of the apparatus to produce a nearly radial static magnetic field in a toroidal examination region within the rock formation surrounding the wellbore. A first coil is wound around a cylindrical annulus core coaxial with the magnets, the core including high magnetic permeability material. The first coil produces pulsed RF magnetic fields oriented parallel to the axis of the apparatus and thus perpendicular to the static magnetic field in the toroidal examination region. This reorients certain nuclear spins and the bulk magnetization of the formation within the examination region resulting from them. The first coil picks up on component of the spin-echo signals of the precessing nucleii.
    Type: Grant

    Date of Patent: March 9, 2004
    Assignee: Baker Hughes Incorporated
    Inventors: Macmillan M. Wisler, Bryan L. Gonsoulin, Larry W. Thompson
