We present a new method to perform wave-equation migration velocity analysis. It properly captures the kinematic update from the ADCIGs and projects that update into the slowness space.
We demonstrated this promising approach using several examples. As shown previously, this method does not suffer from cycle-skipping, does not require moveout parameters picking, and can robustly improve the flatness of the angle gathers.
We plan to further develop this method and apply it to more challenging data.
