Multi-Component Acoustic Characterization of Porous Media by Karel N. van Dalen

By Karel N. van Dalen

The feasibility to extract porous medium parameters from acoustic recordings is investigated. The thesis offers a great dialogue of our uncomplicated realizing of other wave modes, utilizing a full-waveform and multi-component process. concentration lies at the dependency on porosity and permeability the place particularly the latter is hard to estimate. during this thesis, this sensitivity is proven for interface-wave and reflected-wave modes. for every of the pseudo-Rayleigh and pseudo-Stoneley interface waves designated estimates for permeability and porosity might be acquired while impedance and attenuation are mixed.
The pseudo-Stoneley wave is such a lot delicate to permeability: either the impedance and the attenuation are managed by way of the fluid stream. additionally from reflected-wave modes targeted estimates for permeability and porosity will be bought while the mirrored image coefficients of other mirrored modes are mixed. for this reason the sensitivity to permeability is attributable to subsurface heterogeneities producing mesoscopic fluid circulation at seismic frequencies. the result of this thesis recommend that estimation of in-situ permeability is possible, supplied detection is conducted with multi-component measurements. the result of this thesis argely have an effect on geotechnical and reservoir engineering practices.
