Ceduna Sub-basin - Australia - 2015

Springboard 3D GeoStreamer®

True broadband data in the frontier Ceduna sub-basin offshore South Australia
Website Map for Survey Springboard 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. A 40 km 2D well tie to Potoroo-1 was made during acquisition of Springboard MC3D.
The basin’s potential prospective fairways lie within the substantial Late Cretaceous deltaic successions.
