The seismic waves exhibit various types of attenuation while propagating through the subsurface, which is strongly related to the complexity of the earth. The effects of reflection and transmission, together with the geometric spreading effects are already handled by the current Full Wavefield Migration (FWM) and Joint Migration Inversion (JMI) processes. However, the anelastic losses and the effects of fine layering are currently not yet included in the full wavefield modeling (FWMod) process and thereby, not in FWM and JMI. As a result, it will be more difficult to distinguish accurately between different lithologies in our target areas or define clear reflectivities and study their amplitude and phase properties since they distorted by attenuation effects. This research paper proposes an updated version of FWMod that includes the anelastic attenuation effects by adding the estimation and compensation of residual attenuation in the explicit one-way propagators.
