NMO Correction:

After picking the velocities on the CMP gathers we applied NMO correction to obtain the zero offset data. Fig. \ref{600636} shows some CMP gathers in which the early reflections have been flattened. In general later reflections are incoherent and more difficult to flatten. Fig \ref{366200} shows another set of NMO corrected CMP gathers. Notice the conflicting moveouts throughout the data set crossing each other. For this first attempt we carried on the processing with this initial stacking velocities. Later on we  present further processing steps to deal with the conflicting moveouts.
