Interpretation of vitrinite reflectance–depth profiles in the Northern Denison Trough, Bow

The Northern Denison Trough in Australia's Bowen Basin contains data on thermal maturity for Permian sandstone reservoirs. The dataset includes vitrinite reflectance measurements ranging from 0.55% to 0.93% and Rock-Eval Tmax values from 421°C to 447°C, collected as part of the Queensland Government's ZeroGen CO2 Capture and Storage Project. It was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Modeling thermal maturity and burial history based on vitrinite reflectance depth profiles.
• Calibrating hydrocarbon generation potential based on Rock-Eval Tmax and Hydrogen Index data.
• Assessing reservoir quality degradation for CO2 storage based on described diagenetic processes.
• Analyzing the impact of marine flooding surfaces on vitrinite reflectance suppression.

Strengths

• Includes specific numerical ranges for key maturity indicators: vitrinite reflectance (0.55%-0.93%) and Tmax (421°C-447°C).
• Data is tied to a specific geological study area and project (ZeroGen CO2 Capture and Storage Project).
• Provides a calibrated correlation between Rmax and 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.
• Description metadata is limited; actual data quality requires manual inspection after download.
