Estimation of seismic wave attenuation using sonic logging data

Relative Seismic Attenuation Estimation

The end goal of any solid Earth study is to better constrain physical parameters of the Earth (e.g. viscosity, temperature, and mineral composition). As we are unable to directly measure many of these quantities, past a few kilometers in depth, we must content ourselves with indirect estimates by way of experiment and theory. Just as geochemists do this by way of compositional deviations from p...

Seismic Wave Attenuation in Carbonates

Estimation of azimuthally varying attenuation from surface seismic data

Observing the azimuthally varying seismic attenuation in data that show azimuthal velocity anisotropy could contribute not only to the interpretation of the subsurface symmetry systems, but also to the characterization of its physical parameters. In this paper, we estimate azimuthal variations of the P-wave effective quality factor (Q) from field surface seismic data. We also provide an interpr...

seismic attenuation coefficient estimation using smoothed pseudo wigner-ville distribution

elastic energy of seismic wave is lost through propagation into the earth. various factors affect seismic energy. some of them are frequency independent and recovered in processing steps. but other factors such as intrinsic absorption of medium are frequency dependent and cannot be recovered by processing methods. lost energy caused by these factors is called attenuation. there are various meth...
