Adavale Basin 2D Reprocessed Seismic Data Package 2023

The Australian Government’s Data Driven Discoveries program has reprocessed 57 selected multi-era legacy seismic lines, covering approximately 2,356 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.<br>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.<br>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. <br>Both stacks and gather data are provided in SEG-Y format, along with navigation data, velocity, and statics.<strong> </strong><strong>Processed gather data for this survey are available on request from [e-mail] - Quote eCat# 149018</strong>
