    • 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 ...

    • Borehole Seismic Source Radiation In Layered Isotropic And Anisotropic Media: Boundary Element Modeling 

      Dong, Wenjie; Bouchon, Michel; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)
      An algorithm based on the boundary element method is established for modeling seismic source radiation from open or cased boreholes in layered transversely isotropic (TI) media. The axis of symmetry of TI layers is assumed ...

    • Solute Transport In Heterogeneous Porous Media 

      Zhao, Xiaomin; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)
      Solute mass transport in porous media is strongly correlated with pore fluid flow. The analysis of solute transport is an effective means for studying medium heterogeneities. In this study, we discuss the effects of ...
