    • The Study of Wave Propagation in a Borehole Using the Finite Difference Method 

      Pardo-Casas, Federico; Cheng, C. B.; Stephen, Ralph A. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1984)
      Synthetic microseismograms of elastic wave propagation in a fluid-filled borehole were generated using both the finite difference technique and the discrete wavenumber summation technique. For the finite difference ...

    • Nullerical Studies of Body Wave Amplitudes in Full Waveform Acoustic Logs 

      Zhang, Jinzhong; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1984)
      The amplitudes of P and S head waves in a full waveform acoustic log microseismogram are studied numerically as a function of borehole and formation parameters. The technique used is contour integration around the respective ...

    • Determination of Formation Properties in Cased Boreholes Using Full Waveform Acoustic Logs 

      Tubman, Kenneth M.; Cheng, C. H.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1984)
      Wave propagation in bonded and unbonded cased boreholes is examined through the calculation cif synthetic full waveform acoustic logs. The models consist of a central fluid borehole surrounded by a number of fluid and solid ...
