  • <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. Techniques employed included creating a 3D static model, applying noise attenuation methods, surface-consistent deconvolution, and constructing an accurate velocity model to optimise pre-stack time and depth migration. </div><div><br></div><div>Both stacks and gather data are provided in SEG-Y format, along with navigation data, velocity, and statics.</div><div><strong>&nbsp;</strong></div><div><strong>Processed gather data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 149018</strong></div>

  • <div>The Australian Government's Data Driven Discoveries program, in collaboration with the Geological Survey of Queensland, has collected 1715 km of deep crustal seismic data across the Adavale Basin in South-Central Queensland. The L215 Adavale Basin Deep Crustal Seismic Survey was conducted between April and July 2023. The survey acquired 7 regional seismic lines, including 23GA-A1 (550 km), 23GA-A2 (196 km), 23GA-A3 (262 km), 23GA-A4 (94 km), 23GA-A5 (239 km), 23GA-A6 (161 km), and 23GA-A7 (213 km) across the basin. The acquisition of these lines occurred both during the day and night near the towns of Adavale, Charleville, Augathella, Blackall, westward towards Windorah, and north beyond Jericho.</div><div><br></div><div>The Adavale Basin Deep Crustal Seismic Survey complements previous work completed under the Data Driven Discoveries Program, including the Adavale Basin 2D Reprocessed Seismic Data Package (eCat No. 149018) and the newly defined chemostratigraphic framework for the basin (Riley et al., 2023, eCat No. 147773). The survey will deliver a significant uplift in regional shallow and deep crustal seismic information for the Adavale Basin, providing a modern, high-fold dataset that will enhance understanding of the basin's stratigraphy, hydrogeology, resource potential, and underground salt storage opportunities.</div><div><br></div><div><strong>The raw shot gather data acquired during the survey are now available from Geoscience Australia.
