    • Effects Of A Borehole Environment And Residual Hydrocarbon On Stoneley Wave Amplitude And Reflectivity 

      Tao, Guo; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1996)
      In recent years, borehole Stoneley wave amplitude and reflectivity have been used for estimating formation permeability based on the strong correlation between Stoneley wave attenuation, reflectivity and formation fluid ...

    • Measurements Of Shear-Wave Azimuthal Anisotropy From Ultrasonic Dipole Data 

      Tao, Guo; Cheng, Ningya; Zhu, Zhenya; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1995)
      Four methods for analyzing azimuthal anisotropy from dipole logging data are described and attempted in this paper. These techniques are based on the phenomena of flexural wave splitting in anisotropic materials and are ...

    • Measurements Of Shear-Wave Azimuthal Anisotropy With Cross-Dipole Logs 

      Tao, Guo; Cheng, Arthur C. H.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1997)
      Three methods for analyzing azimuthal anisotropy from cross-dipole logs are applied to data from the Powder River Basin in Wyoming. These techniques are based on the phenomena of flexural wave splitting in anisotropic ...
