Multi-dimensional coherence deblending of simultaneous sources

Abstract

Recent seismic exploration research proposes blended acquisition from simultaneous sources with temporal overlap between records to reduce survey time and improve the quality of seismic imaging. However, separating source records for traditional pre-stack processing poses significant challenges. Traditional procedures are incapable to remove interference from other sources equivalent to blended noise. We propose a new approach that enforces simultaneous source coherence across multiple domains in order to estimate the maximum likely distribution of energy amongst the sources.
