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. 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. 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. Both stacks and gather data are provided in SEG-Y format, along with navigation data, velocity, and statics.   Processed gather data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 149018 {"type": "Polygon", "coordinates": [[[142.3, -27.0], [146.6, -27.0], [146.6, -23.8], [142.3, -23.8], [142.3, -27.0]]]} 142.3 146.6 -27.0 -23.8 Adavale Basin DDD - Data Driven Discoveries Precompetitive Data Published_External Sedimentary Basins Seismic Reprocessing Seismology and seismic exploration Download Location Map (zip) [3.46 MB] documentDigital Download Location Map (zip) [3.46 MB] ZIP Download Adavale Reprocessing report and Appendix (zip) [32.0 MB] documentDigital Download Adavale Reprocessing report and Appendix (zip) [32.0 MB] ZIP Download Stacks (zip) [6.72 GB] documentDigital Download Stacks (zip) [6.72 GB] ZIP Download Velocities (zip) [1.53 GB] documentDigital Download Velocities (zip) [1.53 GB] ZIP
