ABSTRACT
The lithology of offshore Trinidad is formed of alternating sequences
of sand and shale dominated layers. Average (effective) anisotropy is
much lower in Trinidad compared to the prevoiusly studied area of
offshore Angola due to the large amount of
sand in the subsurface.
Nevertheless, accounting for anisotropy in seismic processing results
in improved imaging of
structural and stratigraphic features. The imaging improvement is
shown for two different lines from
that region. Inversion for an interval value of the
anisotropy parameter ( |
