ABSTRACT

Passive seismic imaging is based on the fact that by cross-correlating the transmission responses of a medium, one can reconstruct its reflection response. Here, we show a method to directly migrate the transmission responses measured at the surface, based on the shot-profile migration. We also show that the results from direct migration of passive data and from migration of the simulated reflection response are identical. At the end, we also show comparisons between the behavior of the results from the migration process and the simulated reflection responses.
