Palaeogeographic maps for South Perth Shale Supersequence in the Vlaming Sub-basin (Perth

Geoscience Australia produced palaeogeographic maps for the South Perth Shale Supersequence as part of a 2011 National CO2 Infrastructure Plan project. The study maps the distribution and thickness of mudstone facies to characterize the containment potential for CO2 storage in the Vlaming Sub-basin. The work builds on a prior assessment estimating the shale could hold a CO2 column of up to 663 meters.

Use Cases

• Assess CO2 storage site containment potential based on mapped mudstone facies distribution.
• Model subsurface CO2 plume migration based on the variable sealing capacity of the South Perth Shale.
• Identify favorable locations for CO2 injection based on the spatial analysis of effective seal thickness.
• Apply sequence-stratigraphic principles to correlate and predict seal quality across a sedimentary basin.

Strengths

• Based on a three-year project by Geoscience Australia initiated in 2011.
• Applies a sequence-stratigraphic approach to map facies distribution across the basin.
• Analysis includes specific capacity estimates, such as a potential CO2 column of up to 663 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in document formats (HTML, DOCX, PDF), which may require extraction for computational analysis.
