Amplitude-friendly angle migration with stabilized Q

Amplitude-friendly imaging in complex media may also require accounting for attenuation described by a spatially varying Q-model. Here, we extend the ray-based angle migration to account for Q. Any migration with attenuation compensation needs to handle the inherent signal-to-noise ratio of the data or it may boost noise. We present both the use of a stabilization of the effect of Q in the migration and a data-driven reflection enhancement by weighting the summation in the migration to specular events. Both are important in controlling the noise.
