Q-compensated least-squares reverse time migration using low-rank one-step wave extrapolation (2016, methodology): “…fractional Laplacians, Zhu and Harris (2014) proposed a constant-Q viscoacoustic wave equation with separate terms accounting for amplitude loss and velocity dispersion, which was further applied for Q-compensated RTM using both synthetic and field data (Zhu et al., 2014; Zhu and Harris, 2015).”
Modeling acoustic wave propagation in heterogeneous attenuating media using decoupled fractional Laplacians (2014, methodology): “The back-propagation has been successfully demonstrated in applications of Q reversetime migration (Zhu, 2014; Zhu et al., 2014).”
L1−2 minimization for exact and stable seismic attenuation compensation (2018, background): “It is more physically consistent to compensate amplitude absorption and phase dispersion during migration, since these effects associated with anelasticity occur during the wave propagation (Zhang et al. 2010; Zhu et al. 2014; Sun et al. 2015).”
