  • Abnormal pressure determination using nuclear magnetic resonance logging
    Patent number: 6954066
    Abstract: A method and apparatus for determining abnormal pressure zones of a geologic formation using NMR measurements, preferably for logging-while-drilling applications. In a preferred embodiment, a normal compaction trend is constructed using NMR-derived clay bound water volume (CBW) content for non-consolidated subsurface formations or bulk volume irreducible (BVI) and CBW for consolidated formations versus depth. Deviations from this normal compaction trend are used to indicate the presence of shale sections with higher porosity that directly corresponds to an overpressured top seal or transitional zone.
    Type: Grant
    Filed: April 1, 2004
    Date of Patent: October 11, 2005
    Assignee: Halliburton Energy Services, Inc.
