Patents by Inventor Robert M. Leveridge

Robert M. Leveridge 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).

  • Methods and systems for measuring NMR characteristics in production logging
    Patent number: 8860412
    Abstract: Methods and systems for measuring nuclear magnetic resonance characteristics of formation fluid utilizing micro-NMR sensors are provided. The micro-NMR sensors can be used to analyze fluid flowing through the wellbore on a periodic, continuous, and/or batch-mode basis. More efficient sampling and analysis can be conducted using the micro-NMR sensors. In situ analysis and time-lapse logging are also enabled.
    Type: Grant
    Filed: July 28, 2011
    Date of Patent: October 14, 2014
    Assignee: Schlumberger Technology Corporation
    Inventors: Robert M. Leveridge, Reza Taherian

  • Method of determining a radial profile of a formation parameter indicative of formation treatment efficiency
    Patent number: 7746069
    Abstract: A method of measuring a parameter characteristic of a rock formation is provided, the method including the steps of deploying in a section of a well penetrating the rock formation a toolstring combining a tool for generating and measuring responses to a sensing field at different radial depth shells in the rock formation relative to the well and a tool to cause a flow of fluid through the different radial depth shells such that responses to the sensing field are obtained for at least two different radial depth shells and for at least two different flow conditions in said at least two different radial depth shells to determine a radial depth dependent profile of said parameter.
