Abstract:
The southern Surat Basin in Queensland, Australia, may be a prospective region for geological storage of CO2 within the Precipice Sandstone with the Evergreen Formation acting as a sealing cap-rock of the reservoir. The Hutton Sandstone, a major regional aquifer, overlies the Evergreen Formation. Understanding the baseline current hydrogeological and geochemical processes and potential impacts to water resources from CO2 injection are important factors. Data from newly collected field samples of groundwater from the Precipice Sandstone and Hutton Sandstone in the southern Surat Basin are presented, focusing on the stable isotope component of a broader study.
