is a 2D/3D noise suppression module based on prediction filters. It
supplies two options for noise suppression. The first approach is the
standard one described in the literature. It's effective but can
be somewhat harsh, to the point of damaging signal. The second
approach was developed by Techco and is not as aggressive on noise but
does not touch signal in the same way.
FxyPred is also capable of working in prestack mode using
cross-spread gathers. Each cross-spread is treated like a mini-3D
volume. This results in a fairly robust prestack noise
Finally, if you've ever tried fxy predictive approaches on binshared
data, you'll know that it doesn't work that well. When noise is
replicated on neighboring traces, it becomes predictable and is not
removed. Techco has added a modification to beef up the
robustness of the noise suppression in this case.
