Separating Simultaneous Source Data Using Weighted Tau-P Transform

In order to improve seismic acquisition productivity, simultaneous source (SiS) shooting on-shore and offshore, has drawn more and more attention recently. For marine acquisition, SiS means two or more vessels shooting at the same time along different source lines without waiting for the signals from the other to die out. The cross-talk of signals from different sources poses a great challenge to seismic data processing. This abstract introduces a methodology to separate SiS data collected in an ocean bottom node (OBN) survey. The method enhances signals alternately in different shot lines using weighted tau-p transform to extract coherent signals.
