  • Permeability Estimation from Field Data ?

    Burns, D. R.; Cheng, C. H.; Schmitt, D. P.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
    Strong correlations exist between core measured permeability values and the phase velocity and attenuation of the tube wave obtained from full waveform acoustic logs. A number of authors have applied the Biot theory to ...
  • Laboratory Borehole Model ?

    Shortt, E. R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1986)
    An experimental method for acquisition offull waveform acoustic logging (FWAL) data from scaled laboratory borehole/formation models is under development. A spark-gap source, fabricated in the lab, is used in conjunction ...
  • Determination Of In-Situ Permeability From Tube Wave Velocity And Attenuation ?

    Burns, D. R.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1986)
    Recent investigations by a number of different authors have shown that the phase velocity and attenuation of the tube (Stoneley) wave in the borehole is correlated with in situ permeability. Specifically, velocity decreases ...
