Abstract
As part of the National CO2 Infrastructure Plan, Geoscience Australia is undertaking a three year project to provide a detailed assessment of the Vlaming Sub-basin prospectivity for the geological storage of CO2. An important part of this assessment is an evaluation of the seal quality and integrity, including analysis of fault reactivation, signs of seepage, as well as lithological variability within the seal. Over a large area the Gage reservoir is underlain by the Charlotte reservoir (Figure 1). Based on well data, the two reservoirs are at least partially connected. Due to limited data, the Charlotte reservoir was not considered by the previous studies for additional storage capacity. Even if Charlotte Sandstone is not considered for storage, it presents a base seal issue for CO2 storage in the Gage reservoir, which needs to be addressed. The current study mapped the Charlotte reservoir and analysed its potential impact on the containment of CO2. Initial results of this study are outlined below.
