The feasibility to extract porous medium parameters from acoustic recordings is investigated. The thesis gives an excellent discussion of our basic understanding of different wave modes, using a fullwaveform and multicomponent approach. Focus lies on the dependency on porosity and permeability where especially the latter is difficult to estimate. In this thesis, this sensitivity is shown for interfacewave and reflectedwave modes. For each of the pseudoRayleigh and pseudoStoneley interface waves unique estimates for permeability and porosity can be obtained when impedance and attenuation are combined.The pseudoStoneley wave is most sensitive to permeability: both the impedance and the attenuation are controlled by the fluid flow. Also from reflectedwave modes unique estimates for permeability and porosity can be obtained when the reflection coefficients of different reflected modes are combined. In this case the sensitivity to permeability is caused by subsurface heterogeneities generating mesoscopic fluid flow at seismic frequencies. The results of this thesis suggest that estimation of insitu permeability is feasible, provided detection is carried out with multicomponent measurements. The results of this thesis argely affect geotechnical and reservoir engineering practices.
