  • Method of detecting and correcting impulse noise errors in log data
    Patent number: 4677596
    Abstract: Disclosed is a logging technique wherein measured parameters which are inherently weighted average measurement values are inverse filtered to improve the resolution of the measured values. Higher resolution values of log measurements are obtained from information contained in the measurements themselves, and the response function of a logging tool. Measurement errors due to impulsive noise are detected, located and corrected using innovation data contained in the log measurements.
