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.
