One interpretation of a seismic image is the instantaneous scattered wave response of a colocated pseudo-source and pseudo-receiver at each point in the subsurface model. If there is no model perturbation at a point then there will be no instantaneous scattered wave so nothing will be imaged; if something is imaged then there must be a perturbation at that location. By extension, so-called exte…

Seismic interferometry comprises a suite of methods to redatum recorded wavefields to those that would have been recorded if different sources (so-called virtual sources) had been activated. Seismic interferometry by cross-correlation has been formulated using either two-way (for full wavefields) or one-way (for directionally decomposed wavefields) representation theorems. To obtain improved Gr…
