basement in a study area with geologic
conditions that challenge conventional
seismic processing and imaging.
The recorded seismic data in this area
are characterized by a large number of
different order, high-amplitude multiples.
The multiple events are generated from
different depth interfaces between various
rock types, starting from the Upper Cretaceous clastic sediments at the shallow
to medium parts of the subsurface, and
going deeper.
When using Kirchhoff PSDM, the
shape of the low-amplitude migrated reflectivities was distorted by the interbed
multiples. A multiple reflection event
crossing the entire lateral range strongly
dominates this area, forming a complex
image that barely can be interpreted.
On the other hand, full-azimuth imaging and decomposition migration technology provide a clearer and more realistic
image of the complex geological structure
of the Paleozoic basement. Additionally,
a system of subvertical faults and clear
boundaries between the Jurassic and Paleozoic basement are visible and interpretable using full-azimuth imaging and
decomposition.
