Extending illumination using all multiples
What is it about?
The utilization of multiples in imaging and characterization is an emerging methodology. Multiples are waves that are reflected or scattered more than once at the subsurface interfaces and eventually recorded at the seismic detectors. Very often, multiples can reach into the earth to illuminate the shadow zones which primaries cannot reach. This paper is about designing and analyzing 3D seismic acquisition geometries in particular for the case that multiple reflections are considered as signal rather than noise.
Why is it important?
Our analysis shows that multiples are not noise; instead they should be considered as important signals when designing and analyzing an acquisition geometry. Symmetric sampling in seismic acquisition design is based on the analysis of primary reflections only. Asymmetric sampling is the future of acquisition geometry if multiple reflections are used rather than removed.
