A 2026 study by Geoscience Australia established a thermal maturity framework for Permian sandstone reservoirs in the Northern Denison Trough, Bowen Basin, Australia. The dataset includes vitrinite reflectance measurements ranging from 0.55% to 0.93% and Rock-Eval Tmax values from 421°C to 447°C from coals and shales. It was created to evaluate CO2 storage potential and understand diagenetic processes affecting reservoir quality.
Use Cases
- Modeling thermal maturity and burial history based on vitrinite reflectance and Tmax data.
- Assessing CO2 storage potential in sandstone reservoirs based on diagenetic process analysis.
- Calibrating hydrocarbon generation models for coals and shales using Rock-Eval parameters.
- Investigating the impact of marine flooding surfaces on vitrinite reflectance suppression.
Strengths
- Includes specific quantitative ranges for key maturity indicators: vitrinite reflectance (0.55% to 0.93%) and Tmax (421°C to 447°C).
- Data is calibrated for a specific geological province, providing a targeted framework for the Northern Denison Trough.
- Integrates multiple analytical methods (vitrinite reflectance and Rock-Eval) for cross-validation.
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 study area in the Bowen Basin.
