Anelastic attenuation in seismic data: modeling, measurement, and correction

TL;DRAbstract

Various aspects of the anelastic attenuation of seismic data are investigated in this thesis, including modeling, measurement, and correction using Gabor deconvolution. For the modeling of seismic attenuation, a nonstationary convolution model, the reflectivity method, and a finite-difference technique for viscoelastic seismic modeling are described. For the implementation of the nonstationary convolution model, two approaches are proposed to incorporate the impulse response representing attenuation process accurately. The reflectivity method is implemented for stratified anelastic media, and the implementation is validated in terms of producing correct events and amplitudes, accurate incorporation of Q attenuation, and the flexibility to give total and partial response of the media. For the finite-difference method of viscoelastic seismic modeling, results obtained from commercial software are evaluated. For the estimation of seismic attenuation, three new methods are presented, inclu
