Abstract

The wave-equation approach to signature deconvolution and free-surface related multiple elimination of multi-component ocean-bottom data of Amundsen (2001) has recently been linked to seismic interferometry by multi-dimensional deconvolution (MDD). When applied to simultaneous-source data this method can also unravel and reorganise blended data into sequential source responses. We have generated two blended versions of the Volve OBC dataset and compared the ability of MDD to deblend different types of simultaneous-source acquisitions together with suppressing free-surface multiples. Reverse-time migration of the deblended responses produces seismic images of similar quality to those from truly sequential source data.
