We proposed a multistage source separation technique that progressively models the primary signal while eliminating the interference in a signal safe manner (Kamil et al., 2021, Robust multistage separation of simultaneous sources using priors, abstract submitted to EAGE). Different sparsity promoting prior information are utilized at each stage to distinguish signal from blending noise in the transform domain. We discuss common geophysical challenges related to acquisition environments such as land, towed-streamer, ocean bottom node (OBN) and how the proposed approach can be shaped to address these challenges.
