| Summary: | Generally, shallow target has a limited fold coverage that makes the data difficult to process, moreover with the undulated subsurface condition. This case is a problem because the variant dip of the reflector is not included in the conventional seismic data processing parameter. Whereas the frequency of the source wavelet is band-limited which affect the seismic quality and resolution. <br />
<br />
The purpose of this final project is to find the design survey, optimum frequency, and the data processing method which can produce a good result for the undulated shallow target. <br />
<br />
Therefore, conventional seismic data processing and the CRS method were used. The CRS method calculate emergence angle, curvature of the normal wave, and the curvature <br />
<br />
of the NIP wave. <br />
<br />
A set of synthetic shallow target channel model with the variant survey seismic parameter and the frequency of the source wavelet was used to observe the CRS method. As result, a better reflector recovering compared against conventional processing sequence was observed. |
