Paper Summary
High-dimensional (3D) FKxKy inversion is believed to enhance sparsity in the transformed
domain, leading to improved deblending performance for simultaneous source data. While this
approach has been demonstrated using streamer data, its application to Ocean Bottom Node
(OBN) data remains less frequently explored. In this paper, we present two field data examples
that clearly demonstrate the advantages of full-3D inversion over semi-3D approaches in
promoting sparsity within the Fourier domain. Despite the potential for irregularities introduced in the additional cross-shotline direction, our results show that enhanced sparsity more than
compensates for this, resulting in superior deblending outcomes.
