  • Antenna structures for electromagnetic well logging tools
    Patent number: 6690170
    Abstract: The invention refers to antenna configurations for electromagnetic logging tools. The antennas have one or more electrical conductors disposed on a dielectric substrate wrapped around a core or disposed directly on the core. The conductor or conductors are arranged such that the antenna has a first magnetic dipole moment substantially perpendicular to a longitudinal axis of the core. The invention also refers to antennas adapted for mutual balancing using interleaved conductive paths or disks to alter the magnetic dipole moments to mutually balance the antenna system.
    Type: Grant
    Filed: March 29, 2002
    Date of Patent: February 10, 2004
    Assignee: Schlumberger Technology Corporation
    Inventors: Dean M. Homan, Gary A. Hazen, Richard A. Rosthal, David L. Smith, Thomas D. Barber, Paul Michael Ray, Jacques R. Tabanou
