Re-processing (Tape 20)
Re-picking Velocities - Higher velocities for migration
Since under-migration were shown in our migration section, especially for dipping structures, we tried to re-pick higher velocities for this part. As we can see in Fig. \ref{650073}, there's two columns of high coherency in the right panel for this dipping area. Thus we picked higher velocities based on the second column of coherency as shown in Fig. \ref{666874}. CMP increment for velocity analysis was also altered from 50 to 20 in order to acquire more detailed velocity model.
