  • Method and apparatus for measuring acoustic mud velocity and acoustic caliper
    Patent number: 6618322
    Abstract: A method and apparatus for determining acoustic mud velocity and bore hole caliper in a downhole environment. A highly accurate acoustic signal is adjusted for mud velocity as continuously measured. The borehole standoff is utilized to compensated data collected downhole in determining a parameter of interest in the wellbore or an adjacent formation.

  • Method for correcting downhole NMR data contaminated by borehole signals
    Patent number: 6603310
    Abstract: NMR measurements made in a borehole are susceptible to contamination by signals from the borehole fluid. Correction is made for this contamination by using a standoff measuring device to determine the fractional volume of the region of investigation of the NMR tool that lies within the borehole. Using known or determined characteristics of the borehole fluid, a correction is made either to the NMR signals prior to processing or to the processed results of the uncorrected signals.
