Monitoring changes in the Groningen subsurface using non-physical arrivals in seismic interferometryShirmohammadi, F. (author), Draganov, D.S. (author), Wapenaar, C.P.A. (author)Seismic interferometry (SI) refers to the principle of generating seismic responses by crosscorrelating seismic observations at different receiver locations. Theory requires that the boundary sources emit the same energy, have regular spacing and are spaced densely enough. When these assumptions are not met, not only the desired physical...poster 2021

Shirmohammadi, F. (author), Draganov, D.S. (author), Wapenaar, C.P.A. (author)Seismic interferometry (SI) is a principle for retrieving responses between two receivers using cross-correlation. After the retrieval, one of the receivers acts as a virtual seismic source whose response is retrieved at the second receiver. Correct response retrieval relies on assumptions, among other, of a lossless medium being illuminated...poster 2020

van IJsseldijk, J.E. (author), Wapenaar, C.P.A. (author)Seismic time-lapse studies are generally concerned with variations in a specific target zone, situated inside an otherwise static medium. In seismic monitoring the entire reflection response at the surface needs to be remodeled for every change in the target zone. Ideally, however, only the response of the target zone is remodeled, which is then...poster 2019
