ABSTRACT

Multiples can be attenuated either before or after the imaging process. Adaptive subtraction can be applied after migration to eliminate the multiples in the image space. We build a multiple model based on the sea floor reflection, that is kinematically correct. We then perform multiple attenuation to remove the water-bottom multiple in both the image space and the data space.
