Processing including Dip moveout(DMO)

From the contour of the line of data, we could expect the steep structure because the narrow gap exists between contour lines. Also, another line shown in paper of Shatsky rise has spiky structures. Like we assumed, we discovered peak in NMO - migrated image. However, due to the limitation of NMO, we could not make the clear image of it. Also the evident indication of wrong migration, the crossing was discovered. 
NMO cannot display the dipped structure effectively because it assumes the horizontal reflector. In the dipped reflector, we need not only time shift but also horizontal shift. Moreover, NMO works as a dip filter and tends to flatten the result. In contrast, DMO fixes both the time and offset so we thought it could improve our final result. 
To overcome the difficulties above, we applied DMO to given data. The module we used in Paradigm software was "MIGDMO" which performs migration and DMO at the same time and suitable for data after NMO correction. Unfortunately, it does not allow the interactive-picked velocity file. Anyhow, we tried to focus on constructing the peak structure. Even though we did DMO, depending on velocity value the result showed the overlapping problem and unrealistic structures.
