    • Asymmetric Modes of Elastic Wave Propagation in a Fluid-Filled Borehole 

      Jinzhong, Zhang; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)
      A numerical investigation of asymmetric modes of elastic wave propagation in a fluid-filled borehole is treated in this paper. The dispersion curves of guided waves (called flexural waves) and synthetic microseismograms ...
    • Tube Wave Attenuation and In-Situ Permeability 

      Hsui, Albert T.; Jinzhong, Zhang; Cheng, C. H.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)
      The measurement of in-situ permeability is very important in exploration and production logging. Observed data show that tube wave attenuation in full waveform acoustic logs is correlated with formation permeability. It ...
