Springboard Ceduna Merge MC3D | PGS

Ceduna Sub-Basin - Australia - 2015

Springboard Ceduna Merge MC3D 3D GeoStreamer®

20,000 sq.km merged Depth Migrated data in the frontier Ceduna sub-basin offshore South Australia
Website Map for Survey Springboard Ceduna Merge
The Springboard MC3D GeoStreamer survey was acquired with the same acquisition geometry and parameters as the adjacent Ceduna 3D survey. By integrating the Ceduna pre-migrated data into the PGS Springboard MC3D PSDM programme, PGS has generated a fully imaged 20,000 sq,km PSDM volume.
The basin’s potential prospective fairways lie within the substantial Late Cretaceous deltaic successions.
The Springboard survey is true broadband Dual sensor 3D seismic data with pre-stack AVO/AVA fidelity. The Springboard and Ceduna surveys have been processed to depth to create one single merged ~20 000 sq.km MC3D volume.
