    • Elastic Wave Diffraction Of A Piston Source And Its Effect On Attenuation Measurement 

      Tang, X. M.; Toksoz, M. N.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1988)
      The radiation of an elastic wave field from a plane piston source is formulated using the representation theorem, in which the Green's function for an elastic half space is employed. On the basis of this formulation, we ...

    • Viscous Attenuation Of Acoustic Waves In Suspensions 

      Gibson, Richard L. Jr.; Toksoz, M. Nail (Massachusetts Institute of Technology. Earth Resources Laboratory, 1988)
      A model for attenuation of acoustic waves in suspensions is proposed which includes an energy loss due to viscous fluid flow around spherical particles. The expression for the complex wavenumber is developed by considering ...

    • Geophysical Well-Log Analysis In Characterizing The Hydrology Of Crystalline Rocks Of The Canadian Shield 

      Paillet, F . L. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1988)
      A full suite of geophysical logs, including nuclear, electric, acoustic transit-time, acoustic waveform, and acoustic televiewer logs, and high-resolution flowmeter measurements have been used to investigate the lithologic ...
