    • Shear Wave Logging In (Multilayered) Elastic Formations: An Overview 

      Schmitt, D. P.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
      We perform the analysis of the dispersion and attenuation of the modes generated both by a dipole and quadrupole source in a fluid filled borehole surrounded by a (multilayered) elastic formation. The displacement-stress ...

    • Modelling Of Full Waveform Acoustic Logs In Soft Marine Sediments 

      Cheng, C. H.; Wilkens, R. H.; Meredith, J. A. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1986)
      Full waveform acoustic logs obtained from the Deep Sea Drilling Project (DSDP) were modelled using synthetic full waveform acoustic logs. These synthetic logs were calculated using the discrete wavenumber method. The model ...

    • Velocity Analysis Of Multi-Receiver Full Waveform Acoustic Logging Data In Open And Cased Holes 

      Block, Lisa V.; Cheng, C. H.; Duckworth, Gregory L. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1986)
      Average semblance and maximum-likelihood spectral analysis are applied to synthetic full waveform acoustic logging data to determine formation velocities. Of particular interest is the ability of these methods to resolve ...
