Imaging with buried sources

ABSTRACT

Because the shot-profile migration algorithm largely mimics the data acquisition process, simple thought experiments may extend its utility to image the subsurface with less conventional geometries and/or sources. Imaging with the forward- and backward-scattered wavefields in an elastically modeled earth from buried sources is easily implemented without the development of new tools. With this potential in mind, we identify several novel applications of this wave-equation imaging technique, detail the requirements and processing required for its success, and give an example of the process and results by applying these concepts to a crustal-scale imaging experiment using emergent teleseismic plane-waves as sources.
