“…Independent simultaneous source (ISS®) acquisition is one of the techniques used either to provide high density data or to reduce the duration of acquisition (Howe et al, 2008). Using high fold and wide-azimuth designs, ISS® data still permit high quality AVO products (Paramo et al, 2013, Dvorak et al, 2013 and have been shown not to hinder land statics .…”

Independent Simultaneous Source (ISS®) technology is an attractive way to provide high acquisition production rates and affordable higher density seismic imaging. In this paper, we propose an advanced deblending scheme to address the source separation requirement of ISS® data. The deblending scheme includes a) 3D low-rank decomposition based iterative noise modelling, and subtraction, b) signal-to-noise ratio map guided residual denoise and c) erratic noise attenuation. The application is tested on actual shallow water OBC dataset, which was pseudo-blended using a realistic dual vessel acquisition plan. The result shows that this advanced deblending scheme can successfully recover individual source responses. The deblended data have a minimal difference compared with the actual unblended data.
