    • Dispersion Curves and Synthetic Microseismograms in Unbonded Cased Boreholes 

      Tubman, Kenneth M.; Cole, Stephen P.; Cheng, C. H.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1984)
      The dispersion relations and impulse response. are calculated for a geometry consisting of an arbitrary number of coaxial annuli surrounding a central cylinder. The annuli may be either solid or fluid. The formulation ...

    • Full Waveform Acoustic Logging - Where We Are, Where We Are Going 

      Toksoz, M. Nafi; Cheng, C. H.; Garcia, Gilles (Massachusetts Institute of Technology. Earth Resources Laboratory, 1984)
      We have now completed the second year of the Full Waveform Acoustic Logging Consortium. During these two years, we have developed a good understanding of seismic wave propagation in a borehole through both theoretical ...

    • The Effects Of High Pressure-High Temperature On Some Physical Properties Of Ocean Sediments 

      Morin, Roger; Silva, Armand J. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1983)
      A series of laboratory experiments was conducted with four ocean sediments, two biogenic oozes and two clays. Permeability and thermal conductivity were directly measured as a function of porosity and the testing program ...
