Acquisition geometry requirements for generating virtual-source data

Abstract: Using model and field data, this article reviews the virtual-source method and its acquisition geometry requirements. Before we go into the details of the acquisition geometry requirements, let us briefly review the basic concept and the advantages of the virtual-source method. A typical surface seismic experiment has sources on the surface to excite waves that propagate through the subsurface. Surface receivers record the reflected waves. In order to image the subsurface, we migrate the reflected wavefield re… Show more

“…26(a) is merely an artefact from this truncation. Similar artefacts are also known in seismic interferometry and have been well described in the literature (Mehta et al 2008). To reduce such artefacts, the acquisition array can be tapered, but event P will be lost.…”

“…This is because, for a given surface source aperture that feeds the virtual source, the receivers at a depth below the virtual source location have a better opportunity to record the stationary phase response (Snieder et al, 2006;Mehta et al, 2008a). Thus, if two receivers are located at two different borehole and same depth, then there is no possible stationary source position.…”

“…This arrival time is useful information for tomography. However, summing over the sources at other source locations will interfere distractively (Wapenaar et al, 2005;Snieder et al, 2006;Mehta et al, 2008a). Minato et al (2007) found that for vertical borehole sitting, the up-going patterns of the virtual sources located in deepest sections were less recognized in their experiment SUMMARY A virtual source method (VSM) field experiment was performed at the Mirrabooka Trial Aquifer Storage and Recovery Site in Perth Basin, Western Australia.…”
