  • Method and apparatus for improving the vertical resolution of NMR logs
    Patent number: 6903547
    Abstract: An method and system are disclosed for NMR echo-train data acquisition and processing for enhanced vertical resolution for a given signal to noise ratio. In one aspect, the method is based on providing an estimate of non-formation signal components and removing the estimate from the NMR signals. Computation of the estimate is done from the data itself or using a direct measurement of non-formation signals. In another aspect, the functions of reducing coherent noise components is separated from the function of reducing the random noise components, to enhance the resolution of the NMR pulse echo data for a given signal to noise ratio (SNR) of the data. Combination processing is disclosed, which enables efficient filtering of the input NMR data for both relatively high and relatively low SNR of the formation data.
    Type: Grant
    Filed: March 31, 2003
    Date of Patent: June 7, 2005
    Assignee: Halliburton Energy Services, Inc.
    Inventors: Richard F. Sigal, Ron Cherry, Peter Ian Day, James Elmer Galford, John C. Bouton, Ridvan Akkurt, Daniel Lee Miller, Manfred G. Prammer
