    • Homomorphic Processing Of Acoustic Logging Data 

      Ellefsen, K. J.; Burns, D. R.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1991)
      A new processing method, which we developed for the guided waves generated during acoustic logging, accurately estimates the wavenumber when only a few seismograms are available or when the seismograms are irregularly ...

    • The Equivalent Force System Of A Monopole Source In A Fluid-Filled Open Borehole 

      Ben-Menahem, Ari; Kostek, Sergio (Massachusetts Institute of Technology. Earth Resources Laboratory, 1991)
      The elastodynamic body-wave field outside a fluid-filled open borehole due to a monopole source in the fluid, is reduced to the radiation-field due to a suitable equivalent force system (EFS) in the absence of the borehole, ...

    • Secondary Shear Waves From Source Boreholes 

      Meredith, J . A.; Cheng, C. H.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1991)
      The purpose of this paper is to synthesize the most important results of the thesis work of Meredith (1990) concerning radiation from seismic sources in boreholes. Previous studies of radiation from sources in boreholes ...
