Abstract
Systems and methods for improving or generating an image of a surveyed subsurface based on seismic interferometry. A method includes actuating interferometry-based sources over an area to be surveyed to generate seismic waves; recording seismic signals due to the interferometry-based sources, with seismic receivers; selecting traces corresponding to a pair of seismic receivers and an interferometry-based source such that ray paths between the interferometry-based source and the pair of seismic receivers contribute to a Green's function between the two receivers of the pair; cross-correlating the traces for calculating an earth's response associated with a ray propagating from a first seismic receiver of the pair to a second receiver of the pair; and generating an image based on the calculated earth's response.
