Multiple removal strategy for deep and shallow water

This paper discusses the removal strategy of surfacerelated multiples in marine situation with different water depths. Multiples can make interpretation of primary target structures very difficult if they have not been removed from the recorded data in a very early stage. Therefore it is important to define strategies for optimal attenuation of surface-related multiples in various environments. Surface-related multiple elimination (SRME) has been applied very successfully to various marine datasets, but is known to have difficulties with shallow water environment, due to the fact that missing near offsets cannot be reconstructed in a reliable manner. Therefore, a combined methodology with multi-gate predictive deconvolution (MGPD) is suggested to cover all application areas. Examples on synthetic and field data are shown to support this strategy.
