Close full-size image and return to story. Example of a narrow
feature that needs to be seen in a 3-D image. The first
parameter that has to be defined in this 3-D seismic design
method is the smallest (narrowest) horizontal dimension of a
feature that must be seen in the 3-D data volume. For purposes
of illustration, it is assumed the narrowest feature that is to
be interpreted is a meander channel. At least three, and ideally
four, stacking bins (seismic traces) must lie within the
narrowest dimension W of this channel if the channel is to be
reliably seen in the seismic image during workstation
interpretation. Once this minimum channel width W is defined,
the dimensions of the stacking bins are also defined, those bin
dimensions being no wider than W/3, and ideally, they should be
W/4 or less.
