The simultaneous source data could be simultaneously imaged without going through the pre‐separation step. One challenge for this simultaneous imaging approach is the undesired crosstalk artifacts. Understanding the origin and nature of this type of noise is important for practical reasons. We start from the modeling and migration equations for conventionally acquired data, and by introducing the concept of “effective” source we extend these equations naturally to simultaneous source data. The crosstalk term presented in the migration equation is analyzed. Assuming the source time delay is a uniform random variable within a certain range, we show that the product of the angular frequency and the range of source time delay plays an important role in “modulating” the crosstalk noise. This might help us to gain some insights on the simultaneous‐imaging related methods. As a numerical experiment we applied the simultaneous imaging approach to a 2D synthetic simultaneous source dataset. The migration image is close to the conventional migration image.Permalink: https://doi.org/10.1190/1.3513493FiguresReferencesRelatedDetailsCited ByApproaches to improving 2D simultaneous source acquisition and deblendingRay Abma1 September 2021Robust multistage separation of simultaneous sources using priors: Challenges and strategiesYousif Izzeldin Kamil Amin, Rajiv Kumar, Araz Mahdad, Phillip Bilsby, Anu Narayan, Wouter Gerrit Brouwer, Amr Misbah, and Massimiliano Vassallo1 September 2021Simultaneous‐source deblending using adaptive coherence‐constrained dictionary learning and sparse approximation31 March 2021 | Geophysical ProspectingReferences4 February 2021Perfect partial reconstructions for multiple simultaneous sources9 April 2019 | Geophysical Prospecting, Vol. 67, No. 6Signal apparition-enabled parallel-source acquisition of 4D-grade seismic data: Results from a field test in the North SeaKurt Eggenberger, Johan Robertsson, Fredrik Andersson, Dirk-Jan van Manen, Äsmund Pedersen, Lasse Amundsen, Mark Thompson, and Odd Arve Solheim17 August 2017Preserving the discontinuities in least-squares reverse time migration of simultaneous-source dataYangkang Chen, Hanming Chen, Kui Xiang, and Xiaohong Chen27 February 2017 | GEOPHYSICS, Vol. 82, No. 3Preserving the discontinuities in least-squares reverse time migration of simultaneous-source dataYangkang Chen, Kui Xiang, Hanming Chen, and Xiaohong Chen1 September 2016A periodically varying code for improving deblending of simultaneous sources in marine acquisitionShaohuan Zu, Hui Zhou, Yangkang Chen, Shan Qu, Xiaofeng Zou, Haolin Chen, and Renwu Liu6 April 2016 | GEOPHYSICS, Vol. 81, No. 3Independent simultaneous source acquisition and processingRay Abma, David Howe, Mark Foster, Imtiaz Ahmed, Mehmet Tanis, Qie Zhang, Adeyemi Arogunmati, and Gino Alexander7 August 2015 | GEOPHYSICS, Vol. 80, No. 6Imaging blended vertical seismic profiling data using full-wavefield migration in the common-receiver domainA.
