Cooper Basin 2Dcubed seismic reprocessing – 2D PrSTM lines now available for download

Commencing in 2019, TGS has been reprocessing South Australia’s extensive open-file 2D seismic database over the Cooper Basin, using their 2Dcubed technology to generate Pre-Stack Time Migrated and Pre-Stack Depth 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. The area covered by the reprocessing is shown in the map below.

The Department is pleased to announce that the workstation-ready Pre-Stack Time-Migrated SEGY data for the 2D seismic lines that were used in the reprocessing are now available for download, along with the associated statics data. Velocity data will be added to the data package in the next few weeks.

It is expected that the full pseudo-3D PrSTM volumes and the PrSDM data will be available by early 2022. All output data will be immediately open-file and will be made available for download as soon as possible.
