Vitrinite reflectance measurements from 0.55% to 0.93% Rmax and Rock-Eval Tmax values from 421°C to 447°C were collected from Permian sandstone reservoirs in the Northern Denison Trough, Bowen Basin, Australia. The data was generated by Geoscience Australia as part of a study to evaluate CO2 storage potential and understand thermal maturity. The dataset was last updated on 2026-05-14.
Use Cases
- Modeling thermal maturity and burial history based on vitrinite reflectance and palaeotemperature estimates.
- Calibrating Rock-Eval Tmax data with vitrinite reflectance to understand suppression effects in perhydrous coals.
- Assessing hydrocarbon generation potential of coals and shales using Rock-Eval parameters like Hydrogen Index.
- Evaluating the impact of depositional conditions on reservoir quality for carbon storage projects.
Strengths
- Includes specific quantitative ranges for key maturity indicators: vitrinite reflectance (0.55% to 0.93% Rmax) and Tmax (421°C to 447°C).
- Data is contextualized with geological interpretation, linking reflectance suppression to marine flooding surfaces and depositional conditions.
- Provides calibrated maturity data through the correlation of vitrinite reflectance and Rock-Eval Tmax specifically for the Northern Denison Trough.
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.
