Patents by Inventor Tom Springer

Tom Springer 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).

  • Borehole compensation system and method for a resistivity logging tool
    Patent number: 6961663
    Abstract: System and method for borehole compensation. The method includes simultaneously transmitting at least two modulated signals from one or more transmitters; receiving the at least two modulated signals by at least one receiver; and processing the received at least two modulated signals to determine a phase difference and an amplitude attenuation of the transmitted modulated signals, the processing providing borehole compensated data.
    Type: Grant
    Filed: July 20, 2004
    Date of Patent: November 1, 2005
    Assignee: Weatherford/Lamb, Inc.
    Inventors: Paul L. Sinclair, Tom Springer
