    • Electrokinetics Of A Fluid-Saturated Rock Sample: Laboratory Experiments 

      Zhu, Zhenya; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)
      The conversion between seismic and electromagnetic energies was discovered in a fluidfilled porous formation. When seismic waves propagate through a fluid-saturated porous formation, relative motion between the pore fluid ...

    • Nonlinear Semblance Processing For The Evaluation Of An Acoustic Altered Zone Around The Borehole 

      Tezuka, Kazuhiko (Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)
      This paper describes a simple method to evaluate an acoustic altered zone around the borehole using an array of sonic waveforms. The method is based on a semblance velocity analysis and a nonlinear travel time window is ...

    • Stoneley Wave Propagation Across Borehole Permeability Heterogeneities 

      Zhao, Xiaomin; Toksoz, M. N.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)
      An important application of borehole acoustic logging is the determination of formation permeability using Stoneley waves. Heterogeneous permeable structures, such as fractures, sand-shale sequences, etc., are commonly ...
