Jurassic Sandstone Porosity and Permeability in the Eromanga Basin

Diagenesis data for Jurassic and Lower Cretaceous sandstones from the Eromanga Basin in New South Wales. The dataset likely contains measurements of core porosity and permeability for quartzose and volcanolithic petrofacies, detailing authigenic minerals and pore types. It is hosted by the Australian Ocean Data Network and was last updated on 2026-04-16.

Use Cases

• Compare porosity-permeability relationships between quartzose and volcanolithic sandstone petrofacies.
• Model aquifer function based on the described 29% mean porosity and 676 md mean permeability of quartzose sandstones.
• Analyze diagenetic sequences based on the temporal order of authigenic minerals listed in the description.
• Correlate depositional environments with porosity-permeability distribution patterns as mentioned.
• Study the impact of clay infiltration and grain dissolution on primary porosity preservation.

Strengths

• Provides specific mean porosity (29%) and permeability (676 md) values for quartzose sandstones.
• Provides specific average porosity (35%) and permeability (125 md) values for volcanolithic sandstones.
• Description details distinct diagenetic processes and authigenic mineral sequences for two petrofacies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific basin study.
