Deterministic application of a horizontal trend
volumes in the trended case are half that calculated
for a model with the trends removed, with all other
model variables unchanged. Stationarity is over-
come and the concept dominates the modelling.
The source of the trend can be an extension of
the underlying data, as in the example above, or a
less data-independent
seismic attributes - the 'soft conditioning'

2.7.4.3 3D Probability Volumes
The 3D architecture can be directly conditioned
using a 3D volume - a natural extension of the
process above. The conditioning volume can be
concept based on a
