Abstract

The problem of diffracted multiple attenuation is tackled through an application of 3D SRME. The impact of changes in acquisition geometry is assessed by performing multiple attenuation on synthetic data. We demonstrate that 3D SRME can successfully attenuate surface-related diffracted multiples, provided the necessary full wavefield is either acquired or reconstructed. We focus our study on the impact of acquisition geometry on the quality of multiple suppression and show that acquiring higher-density data can lead to significant improvements in diffracted multiple attenuation. A large gap in the quality of multiple suppression remains between the case when the full wavefield is obtained directly through modeling and the case when it is obtained using DMO-based data reconstruction. This observation points to the need for further research to determine whether alternative data reconstruction methods can yield greater improvements in SNR while simultaneously allowing sparser, less costly acquisition geometries.
