a simple homogeneous Earth, three shear-wave (S-wave) images
can be made from 9C3D seismic data. One image can be made from
the SV mode, a second image can be made from the SH mode, and
a third called the C-wave can be made from the "converted"
SV mode created by P-to-SV mode conversion at subsurface interfaces.
Only one S-wave image can be created from 3C3D data, that being
a C-wave image. Independents who are interested in S-wave seismic
technology need to be informed about the differences, similarities,
advantages, and disadvantages of these three S-wave imaging
of this study is to create all three S-wave data volumes (SV, SH,
C) across the same prospect(s) and to document the relative merits
of each S-wave seismic mode. This
research does not require field work. The
