In the process imagging seismic, reflector slope should be calculated, because Reflections on the field boundary layer which has a slope (dip) in a CMP gather have varying reflection point (smearing). This resulted in artificiality reflector positions represented by the peak point of epic hyperbole. Therefore, the conventional method using NMO correction can’t give good results for the characteristics of this model. <br /> <br /> <br /> <br /> <br /> In this final project will use a model with a steep slope. DMO method is a method that is suitable for reflector case like this, because by doing DMO correction, smearing effect in a CMP gather will be reduced, so that the trace within a CMP gather after DMO correction comes from the single reflection point. <br /> <br /> <br /> <br /> <br /> New method developed at this time (Common Reflection Surface), developed of NMO and DMO methods, should be tested if the ability to apply on this model, so we can know the ability of these methods when applied to models This, in order to find suitable methods to be applied on models with the same characteristics. <br /> <br /> <br /> <br /> <br /> Through the spatial variation geometry approach, expected to be able to analyze the ability of each imaging method in seismic processing and quality of the resulting stack cross section for the model used.
