Field data example

Many have used the Mississippi Canyon multiples dataset from WesternGeco as a benchmark for testing multiple removal methods (, ,,,,,,,,). We now use the strong free-surface multiples present in these data to generate pseudo-primaries. Figure 12 shows a source-offset cube of the recorded data; we created split-spread data from the off-end marine acquisition using source-receiver reciprocity. The near-offset gap in this case is six traces, which is much smaller than that in the Sigsbee2B example. However, these field data contain much more than just primary and multiple reflections.
