Abstract

The imaging condition needs special attention in imaging of separated wavefields because of the increased complexity of the source wavefield. Starting from reciprocity relations and using pressure-normalized wavefield decomposition, we introduce a new deconvolution imaging condition in which the subsurface image is determined from the upgoing pressure and the downgoing vertical particle velocity wavefields. In a recent work, Lameloise et al. (2012) elaborated on migration of separated wavefields using dual-sensor towed streamer data of a simultaneous source system. This work was the starting point to set up a feasibility study and test the new imaging condition. Synthetic and real data examples showed that this approach leads to a better match between the depth images of multiples and primaries.
