Forward propagating the recoded data
In this study, we have looked at the prospect of using the seismic shot record as a source for RTM. In the process,
we analyzed the different interactions between the main components of the shot record (direct, primary, and multiple arrivals) as a result of the correlation-based imaging condition. Of those nine interacting terms from crosscorrelating the forward propagated with the backward propagated recored data, two correspond to direct imaging the primaries and multiples and four are potential crosstalk noise. However, the crosstalk noise, which result from the interaction of primaries and multiples from different reflections tend to be relatively small and can be controlled by filtering the forward propagated recorded field.
