Chapter 6: Attenuation of 3D subsalt multiples with Gulf of Mexico dataset

In this chapter I tie up the different components presented in the previous chapters. I attenuate subsalt multiples from the real dataset migrated in the previous chapter. I show that some multiple attenuation can be achieved by muting the multiple energy away from zero subsurface offsets in SODCIGs and stacking the results. I obtain much better attenuation of the multiples by applying Radon filtering on azimuth-stacked ADCIGs.
