    • Detection and Characterization of Fractures from Generation of Tube Waves 

      Hardin, Ernest; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)
      Field testing has been conducted to evaluate a model which predicts the permeability and orientation of a permeable zone, in a deep water well in crystalline rock. Tube waves are generated by seismic P-waves incident on ...

    • 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 ...

    • Effects Of Layer Boundaries On Fwal And Dip Estimation (Oblique Events) 

      Paternoster, Benoit; Larrere, Marc (Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)
      Data recorded by the full waveform acoustic logging tool EVA shows events generated at acoustic layer boundaries. These can be interpreted as reflections on and transmissions through interfaces. Ray modelling shows that ...
