CO2 Storage Potential Analysis of Gage Sandstone in Vlaming Sub-basin

A case study assesses the Gage Sandstone in the 23,000 km² Vlaming Sub-basin for CO2 storage suitability. The analysis integrates 2D seismic interpretation, well log analysis from 8 wells, and biostratigraphic data to map a submarine fan system with reservoir porosities of 23-30%.

Use Cases

• Model CO2 storage capacity using reservoir porosity (23-30%) and permeability (200-1800 mD) data from the Gage Sandstone.
• Map paleogeographic evolution of the submarine fan system using interpretations of seismic facies and well log data.
• Analyze sediment transport directions and depositional environments using data from the G. mutabilis dinoflagellate zones.
• Characterize reservoir thickness distribution, up to 360 meters, based on seismic and well log interpretations near the Badaminna Fault Zone.

Strengths

• Analysis covers a 23,000 km² geographical area in the offshore southern Perth Basin.
• Integrates multiple data types: 2D seismic interpretation, well log analysis from 8 wells, and biostratigraphic review.
• Provides specific reservoir property ranges, including porosity (23-30%) and permeability (200-1800 mD).

Limitations

• Data is presented as a case study in document formats (DOCX, PDF, HTML), not as a structured, queryable dataset.
• Sample data and column definitions are unavailable, limiting direct analytical use.
• Findings are specific to a local geological study and may not be generalizable.
