Central Australian Basins 2D Reprocessed Seismic Data Package 2023

<div>The Central Australian Basins 2D Seismic Reprocessing Project is an initiative under Geoscience Australia's "Australia’s Future Energy Resources" (AFER) program, funded by the Australian Government through the "Exploring for the Future" (EFTF) program. The project aims to assess the untapped resource potential of selected underexplored onshore sedimentary basins in terms of natural gas, oil, and groundwater, while also investigating opportunities for geological storage of carbon dioxide and hydrogen.

Purpose

The Central Australian Basins 2D Seismic Reprocessing Project, an initiative under Geoscience Australia's AFER program, aims to comprehensively evaluate the untapped potential of various underexplored onshore sedimentary basins in Australia. Funded by the Australian Government's EFTF program, the project focuses on natural gas, oil, and groundwater resources, while also exploring opportunities for geological storage of carbon dioxide and hydrogen. The initiative uses modern seismic processing techniques to enhance the quality and resolution of legacy seismic lines, thereby contributing to an improved understanding of geological evolution across different time periods and basins. Available in SEG-Y format, the reprocessed data includes both stack and gather data, as well as ancillary information such as velocity and statics. The dataset serves as a pre-competitive tool aimed at encouraging investment in mineral, energy, and groundwater exploration by providing high-quality, actionable data to interested parties.

Statement

<div>The reprocessed 2D seismic data in this project has its roots in seismic surveys conducted during the 1970s and 1980s. Originally acquired as part of various geological exploration initiatives of that era, these legacy lines have been given new life through the Central Australian Basins 2D Seismic Reprocessing Project. Funded by the Australian Government through the "Exploring for the Future" (EFTF) program and under the aegis of Geoscience Australia's "Australia’s Future Energy Resources" (AFER) program, this data has been thoroughly reprocessed.</div><div><br></div><div>Utilising modern seismic processing techniques, the data underwent several rounds of enhancements. Algorithms for noise attenuation, 3D static modelling, minimum phasing of vibroseis data to match dynamite lines, and surface-consistent deconvolution were employed. The goal was to improve the quality of seismic reflectors and faults, reduce noise, and optimise frequency content for various target depths. The reprocessing has brought these multi-vintage legacy lines into a more usable and accurate format, available in SEG-Y, with additional navigation data, velocity, and statics.</div><div><br></div><div>This reprocessed dataset is housed and managed by Geoscience Australia.
