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

A geological dataset from the Northern Denison Trough, Bowen Basin, Australia, containing vitrinite reflectance and Rock-Eval pyrolysis measurements. The data was collected by the Australian Ocean Data Network as part of a study to evaluate CO2 storage potential and establish a thermal maturity framework for Permian sandstone reservoirs. It includes measurements from the Aldebaran Sandstone through to the Catherine Sandstone, with reflectance values ranging from 0.55% to 0.93% Rmax.

Use Cases

• Modeling thermal maturity and paleotemperature history based on vitrinite reflectance-depth profiles.
• Assessing hydrocarbon generation potential of coals and shales based on Rock-Eval Tmax and Hydrogen Index data.
• Evaluating the impact of depositional conditions (e.g., marine flooding surfaces) on vitrinite reflectance suppression.
• Calibrating basin models for CO2 storage site characterization using integrated vitrinite and Rock-Eval data.

Strengths

• Includes paired vitrinite reflectance (Rmax 0.55%-0.93%) and Rock-Eval (Tmax 421°C-447°C) measurements for calibration.
• Data covers a specific stratigraphic interval from the Aldebaran Sandstone through the Catherine Sandstone.
• Analysis identifies specific depositional effects (perhydrous vs. subhydrous vitrinite) influencing data interpretation.

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 Northern Denison Trough study area.
