Recursive Transformation of Multiples into Primaries - Data Examples

In most seismic processing flows multiples have been considered as noise and, therefore, are discarded after the removal process. In this paper it is argued that multiple reflections contain a wealth of information that should be used in seismic processing to improve the resolution of reservoir images beyond current capability. The proposed method, multi-channel weighted cross-correlation (WCC), in combination with surface-related multiple elimination (SRME) allows the transformation of multiples into primaries for surface seismic data. The latter means that nonlinear seismic imaging can be implemented by a number of linear steps.
