  • Formation-based interpretation of NMR data for carbonate reservoirs
    Patent number: 6977499
    Abstract: An apparatus and method for determining a parameter of interest of a formation composed of carbonate rock. A nuclear magnetic resonance (NMR) sensor assembly produces a pulsed RF field designed for obtaining measurements indicative of the parameter of interest of the formation. A downhole processor processes the measurements for obtaining BVI and BVM using a cutoff time based on classification of the carbonate. Further processing is done to estimate the permeability of the carbonate.
    Type: Grant
    Filed: May 21, 2003
    Date of Patent: December 20, 2005
    Assignee: Baker Hughes Incorporated
    Inventors: Christian Kiesl, Thomas Kruspe, Holger F. Thern, Iris Surholt
