Geoscience Australia Data created a thermal maturity framework for Permian sandstone reservoirs in the Northern Denison Trough, Bowen Basin. The dataset includes vitrinite reflectance measurements ranging from 0.55% to 0.93% Rmax and Rock-Eval Tmax values from 421°C to 447°C from coals and shales. This work was part of the Queensland Government's ZeroGen CO2 Capture and Storage Project, with metadata last updated in April 2026.
Use Cases
- Modeling thermal maturity and burial history based on vitrinite reflectance-depth profiles.
- Calibrating Rock-Eval Tmax data with vitrinite reflectance for basin-specific maturity correlations.
- Assessing hydrocarbon generation potential of coals and shales in the studied interval.
- Evaluating the impact of perhydrous and subhydrous vitrinite on paleotemperature calculation accuracy.
Strengths
- Includes specific quantitative ranges for key maturity indicators: vitrinite reflectance (0.55% to 0.93% Rmax) and Rock-Eval Tmax (421°C to 447°C).
- Data is tied to a specific geological study and government project (ZeroGen CO2 Capture and Storage Project), providing context.
- Analysis covers multiple stratigraphic units from the Aldebaran Sandstone to the Catherine Sandstone.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Description metadata is limited; actual data quality requires manual inspection after download.
