DOI: 10.1016/j.jappgeo.2018.02.027
Abstract: Abstract In a simultaneous source survey, no limitation is required for the shot scheduling of nearby sources and thus a huge acquisition efficiency can be obtained but at the same time making the recorded seismic… read more here.

DOI: 10.1093/gji/ggac222
Abstract: The simultaneous source data obtained by simultaneous source acquisition contain crosstalk noise and cannot be directly used in conventional data processing procedures. Therefore, it is necessary to deblend the blended wavefield to obtain the conventionally… read more here.

DOI: 10.1109/access.2020.3046638
Abstract: Simultaneous source acquisition can enhance the seismic data quality or improve the field acquisition efficiency. However, one of the disadvantages is that the simultaneous source data are often obtained on a non-uniform sampled grid in… read more here.

DOI: 10.1109/lgrs.2017.2772857
Abstract: Simultaneous-source shooting can help reduce the acquisition time cost, but at the expense of introducing strong interference (blending noise) into the acquired seismic data. It has been demonstrated previously that the deblending problem can be… read more here.

DOI: 10.1109/lgrs.2022.3174106
Abstract: Simultaneous source acquisition is becoming more promising than the traditional seismic acquisition by firing multiple sources with a short interval time, which improves acquisition efficiency and enhances data quality. However, the blended interference severely obscures… read more here.

DOI: 10.1109/tgrs.2021.3086834
Abstract: We solve the simultaneous source separation problem by adopting the projected gradient descent (PGD) method to iteratively estimate the data one would acquire via a conventional seismic acquisition. The projection operator is a windowed robust… read more here.

DOI: 10.1190/geo2016-0240.1
Abstract: ABSTRACTHigh-resolution seismic imaging requires noise attenuation to achieve signal-to-noise ratio (S/N) improvements without compromising data bandwidth. Amplitude versus offset analysis requires good amplitude fidelity in premigration processes. Any nonreflected wavefield energy in the data will… read more here.

DOI: 10.1190/geo2016-0456.1
Abstract: ABSTRACTThe simultaneous-source shooting technique can accelerate field acquisition and improve spatial sampling but it will cause strong interferences in the recorded data and artifacts in the final image. The previously proposed structural smoothing operator can… read more here.

DOI: 10.1190/geo2022-0085.1
Abstract: Simultaneous shooting offers opportunities for significant cost savings in seismic data acquisitions. The most common strategy uses random delay shots where source separation is achieved during the processing stage, thereby doubling source densities. We demonstrate… read more here.
