  • Measurement of permeability in borehole in the presence of mudcake
    Patent number: 9366777
    Abstract: The present disclosure relates to methods and apparatuses for evaluating a porous earth formation. The method may include: generating an acoustic wave in a borehole fluid; measuring an attenuation of the acoustic wave; and estimating a permeability of an earth formation acoustically coupled to the borehole fluid using the estimated attenuation and a theoretical attenuation. The method may also include estimating a theoretical attenuation for the borehole fluid using acoustic properties of the borehole fluid. The apparatus for performing the method may include: an acoustic source, an acoustic sensor, and a processor configured to estimate the attenuation of an acoustic wave generated by the acoustic source.
    Type: Grant
