In deep-water
The pre-stack depth migrated data
identify autochthonous and allochthonous salt and
associated archetypes. The salt bodies show predominantly northwest-southeast
structural grain depicting the regional sedimentary depositional dips. The
autochthonous Jurassic Louann (mother) salt, Jurassic
sediments and the overlying Cretaceous and Paleogene
sequences are well manifested in the data sets. The new Paleogene/Mesozoic
play is typically characterized by broad rollover structures created by the
loading of sediments, deflation and withdrawal of the mother salt and
subsequent collapse of the sediments. The good imaging of the sedimentary
section and folded structure below the salt helps delineate the new Paleogene/Mesozoic play, which has proven successful in
many parts of the P-45 area, but is yet to be tested in
