Synthetic 1

A synthetic interval velocity model was built and a CMP gather was modeled using a finite difference code (Figure 1)

For this gather, a velocity analysis is performed to obtain the RMS velocity $\bold d$ (equation 1). Figure 2 shows the rms velocity curve picked from the data, and Figure 3 shows a comparison of the interval velocity $\bold u$ obtained by the methodology described above, the RMS velocity $\bold d$ obtained from the velocity analysis, and the remodeled RMS velocity ($\bold{d_{remod}}$= $\bold{Cu}$).

This comparison shows that the remodeled RMS velocity is similar to the picked RMS velocity. This similarity prove that the method used works well.
