Ceduna Sub-basin - Australia - 2011

Ceduna 3D

Depth Migrated data in the frontier Ceduna sub-basin offshore South Australia
Website Map for Survey Ceduna MC3D
The Ceduna sub-basin has become a hot spot for exploration activity following gazettal round awards to several major E&P companies and represents a massive and under-explored frontier area. The Ceduna MC3D complements the Springboard MC3D to now create one single merged ~20 000 sq.km MC3D volume.
The basin’s potential prospective fairways lie within the substantial Late Cretaceous deltaic successions.
