Mitchell Gentry 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).

  • CONDUCTIVE CEMENT FORMULATION AND APPLICATION FOR USE IN WELL
    Publication number: 20100212902
    Abstract: Method for cementing a well comprising a hydraulic cement, water, carbon fiber and graphite are provided. The synergy achieved from combining fibers and particulates into the same sample results in a composite slurry with improved electrical properties and easy-to-optimize rheologies. Method for measuring resistivity through casing thanks to the nature of the cement composition is also provided.
    Type: Application
    Filed: May 4, 2010
    Publication date: August 26, 2010
    Inventors: Robert Williams, Emmanuel Therond, Terry Dammel, Mitchell Gentry

  • Conductive cement formulation and application for use in wells
    Patent number: 7732381
    Abstract: The invention provides a cement slurry composition for cementing a well comprising a hydraulic cement, water, carbon fiber and graphite. Compositions of the current invention combine the benefits obtained from adding carbon fiber and graphite to the cement composite. The synergy achieved from combining fibers and particulates into the same sample results in a composite slurry with improved electrical properties and easy-to-optimize rheologies.
