Abstract:

The Springbok Sandstone (Surat Basin, Australia) overlies the Walloon Subgroup, which is a significant target for Coal Seam Gas (CSG) production. In order to assess and mitigate possible groundwater impact of CSG production, it is critical to define groundwater flow units. This is challenging for the Springbok Sandstone due to the significant heterogeneity of its mineralogy and lithology as well as hydrogeological properties. The main objective of our research is to reduce the uncertainty of the hydrogeological characterisation of the Springbok Sandstone through a comprehensive comparison with a well-understood aquifer in the Surat Basin: the Precipice
Sandstone.
