South Perth Shale Supersequence Palaeogeographic Maps For CO2 Storage Assessment

A 2011 project by Geoscience Australia produced pre-competitive data for assessing CO2 storage potential in Western Australia's Vlaming Sub-basin. The study maps the distribution and thickness of mudstone facies within the South Perth Shale Supersequence to characterize its sealing capacity. It builds on prior work estimating the formation could hold a CO2 column up to 663 meters.

Use Cases

• Mapping the spatial distribution of mudstone facies to identify high-quality seal regions for CO2 containment.
• Analyzing the thickness variation of the effective seal across the basin to model storage capacity.
• Applying sequence-stratigraphic interpretations from the maps to predict seal integrity in untested locations.
• Correlating mapped facies distributions with sealing capacity estimates from Mercury Intrusion Capillary Pressure (MICP) tests.

Strengths

• Maps derived from a detailed sequence-stratigraphic approach applied across the entire Vlaming Sub-basin.
• Analysis builds on prior quantified estimates, such as a 663-meter CO2 column capacity.
• Project was part of a national three-year assessment plan (NCIP), suggesting structured data collection.

Limitations

• Specific row counts, column details, and sample data for the underlying spatial data are unavailable.
• The core analysis relies on a 2006 study and MICP tests from that period, which may not reflect current conditions.
• File formats (DOCX, PDF, HTML) suggest the primary outputs are reports and figures, not structured, queryable datasets.
