Abstract:Marine towed-streamer blended data are usually challenging to deblend because of the low dimensionality of the data. While the present ocean-bottom-cable (OBC) surveys produce well-sampled 3D receiver gathers, towed-streamer data have a lower sparsity in the transformed f - k domain. Here, we revisit two practical strategies to improve deblending performance. In the first strategy, we revisit applying 3D deblending to 2D surveys, which considers the shot domain as a sparsity-constrained domain. We compare the … Show more
