Abstract

We show here a successful case study of applying 3D model-based water-layer demultiple (MWD) for shallow water data from West Africa. 3D MWD (Wang et al., 2011) is especially useful when the water-bottom is recorded beyond the critical angle, when the water depth is roughly less than half the near offset. We show that in such an environment, 3D MWD provided an advantageous alternative to 3D SRME (Verschuur et al, 1997) for removing water-layer-related multiples. We also show that the simultaneous subtraction of the 3D MWD and SRME models better attenuates the multiples than the separate subtraction of the two models.
