TGS has reprocessed South Australia's extensive open-file 2D seismic database over the Cooper Basin, using their 2Dcubed technology to generate Pre-Stack Time Migrated 2D and pseudo-3D outputs over the basin. Field data from 3855 lines of 2D seismic data acquired between 1985 and 2012 were used as inputs into the study, which is being undertaken with the support of Chevron Australia Pty Ltd. This data package contains workstation-ready full-offset SEGY data for the merged 2D3D PrSTM volume i.e. the pre-existing full-offset final data from the various 3D seismic surveys within the area-of-interest has been merged into the pseudo-3D PrSTM volume generated from the 2D lines. The supplied full-offset final volume (approximately 160Gb) was split into 10 parts to allow for easier downloading and manipulation in interpretation software.
