Vitrinite Reflectance and Rock-Eval Data for Permian Sandstones, Northern Denison Trough

Geoscience Australia Data provides a dataset from a study establishing a thermal maturity framework for Permian sandstone reservoirs in the Northern Denison Trough, Bowen Basin. The data includes mean maximum 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. This work was conducted as part of the Queensland Government's ZeroGen CO2 Capture and Storage Project, with a last recorded update in April 2026.

Use Cases

• Modeling thermal history and maximum burial temperatures based on vitrinite reflectance data.
• Assessing CO2 storage potential of sandstone reservoirs based on described diagenetic processes affecting porosity and permeability.
• Calibrating maturity models using the described correlation between vitrinite reflectance (Rmax) and Rock-Eval Tmax.
• Investigating the impact of perhydrous and subhydrous vitrinite on paleotemperature calculation errors in high volatile bituminous coals.
• Evaluating hydrocarbon generation potential of coals versus shales using Rock-Eval parameters like Hydrogen Index.

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, described geological study area (Northern Denison Trough, Bowen Basin) and project (ZeroGen CO2 Capture and Storage Project).
• The description provides a detailed geological context, including discussion of depositional effects and data suppression factors.

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 data_gov_au, being focused on a single Australian basin.
