Completed 2021 Surat and Galilee basins
This project collected airborne electromagnetic (AEM) data across 2 areas: the Surat and Galilee geological basins.
These data were released for inclusion in future studies and have been combined with other geophysical and geological data to characterise aquifer architecture in the Australian Government funded project .
AEM provides a potential cost-effective alternative to map near-surface Neogene faults (<100 to 200 m below surface). The lower per-kilometre costs of AEM data acquisition compared to seismic reflection data enable industries, government and academia to collect more data and better understand aquifer hydrodynamics and structural compartmentalisation of sedimentary basins.
New data acquisition
The Surat-Galilee project acquired 4,767 line kilometres of AEM data across parts of the Surat and Galilee geological basins in 2017. The survey acquired data either coincident or proximal to existing seismic reflection surveys for ease of comparison between 2 datasets. Geoscience Australia used these new AEM data to aid interpretation as part of the project.
