Abstract
<div>The Australian Government’s Data Driven Discoveries program has reprocessed 60 selected multi-era legacy seismic lines, covering approximately 2,520 km across the Adavale Basin, south-central Queensland. Reprocessing of legacy seismic data from the Adavale Basin aims to create a modern, consistent and integrated seismic dataset that provides new insights into the geological structure of the basin and deepens our understanding of the basin’s minerals, energy, underground storage and groundwater potential.</div><div><br></div><div>The reprocessed lines were chosen to tie into 5 wells that were previously sampled for chemostratigraphic analysis through the Data Driven Discoveries program (Riley et al., 2023, eCat 147773), including Allendale 1, Boree 1, Gilmore 1, Quilberry 1 and Stafford 1. The Adavale Basin 2D Reprocessed Seismic Data Package also complements new deep crustal seismic data being acquired in the Adavale Basin by the program.</div><div><br></div><div>The reprocessing workflow prioritised enhancing the image quality of the selected legacy seismic lines, reducing noise, and fine-tuning frequency content for specific target depths.

Purpose
The primary purpose of the Adavale Basin 2D Seismic Reprocessing Initiative is to enhance the exploration potential of the Adavale Basin in Australia. Funded by the Australian Government under Geoscience Australia's Data-Driven Discoveries Program, this initiative focuses on reprocessing seismic data to illuminate the basin's potential for oil, natural gas, and groundwater extraction. Additionally, it explores the geological storage capacities for carbon dioxide and hydrogen. The project aims to encourage investment in these sectors by delivering pre-competitive data. Furthermore, this initiative contributes to our broader geological knowledge by linking findings in the Adavale Basin with existing data on other significant Australian basins, including the early Palaeozoic Amadeus and Warburton basins, as well as the Permian-Triassic Pedirka and Simpson basins.

Lineage
<div>The reprocessed 2D seismic data in the Adavale Basin 2D Seismic Reprocessing Initiative has its origins in surveys conducted between 1979 and 1986. Initially gathered as part of different geological exploration projects during that period, this legacy data has been revitalised through the initiative. Sponsored by the Australian Government under Geoscience Australia's Data-Driven Discoveries Program, the data has undergone comprehensive reprocessing to enhance the exploration potential of the Adavale Basin.</div><div><br></div><div>Employing cutting-edge seismic processing methods, the data has gone through multiple rounds of improvements. Techniques such as noise attenuation, 3D static modelling, minimum phasing to synchronise vibroseis and dynamite lines, and surface-consistent deconvolution have been utilised. The aim was to refine the quality of seismic reflectors and faults, minimise noise, and adjust frequency content for a range of target depths. This has transformed the data into a more functional and precise format, available in SEG-Y format, along with supplementary navigation data, velocity, and statics.</div><div><br></div><div>Managed and stored by Geoscience Australia, this reprocessed dataset serves to boost both investment and geological understanding. It explores the Adavale Basin's potential for minerals, energy and groundwater extraction, as well as CO2 and hydrogen storage. The data is accessible upon request through clientservices@ga.gov.au, quoting the eCat number 149018.</div>
