Paper presented at the SEG International Exposition and Annual Meeting, October 11–16, 2020
Paper Number: SEG-2020-3427913
... Multi-source seismic acquisition technology allows different sources to be activated at the same time, to obtain blended seismic data from multi-source. This technology has high efficiency and reduce the acquisition cost effectively. The disadvantage of this method is that crosstalk noise caused...

Theoretical models and field data processing verify the effectiveness of the algorithm and suitability for complex models. Presentation Date...

However, it is ineffective if the noise appears as high-wavenumber arti- facts, especially at shallow depths. A second example arises...

Furthermore, we suppress the crosstalk noises and the artifacts caused by summation by randomly regenerating the super-shots between iterations. To test our algorithm, we implement fast FWI...
