Abstract

This study deals with the extension of the frequency-domain full-waveform inversion/modelling (FWI) from the acoustic to the viscoacoustic case in application to the wide-aperture seismic data recorded in the Polish Basin. Attenuation was accounted for by introduction of complex velocities. Two inversion strategies were tested: (i) coupled inversion in which Qp and Vp were simultanously inverted and (ii) decoupled inversion in which Vp model was taken from the acoustic inversion and remain fixed during the inversion for Qp. The latter approach produced preferred attenuation model. Together with some a priori information from well-log data and laboratory measurements we interpret recovered high attenuation anomalies in terms of fluid saturation and rock permeabilities.
