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

A geological study dataset from the Northern Denison Trough in Australia's Bowen Basin, focusing on Permian sandstone reservoirs. The dataset includes vitrinite reflectance measurements ranging from 0.55% to 0.93% Rmax and Rock-Eval Tmax values from 421°C to 447°C, collected to assess thermal maturity and CO2 storage potential. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Modeling thermal maturity and paleotemperature history based on vitrinite reflectance (Rmax) values.
• Calibrating vitrinite reflectance data using supporting Rock-Eval parameters like Tmax and Hydrogen Index.
• Assessing hydrocarbon generation potential of coals and shales in specific stratigraphic intervals.
• Evaluating factors like vitrinite suppression (perhydrous/subhydrous) that introduce error in paleotemperature calculations.

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).
• Provides a calibrated, location-specific correlation between Rmax and Tmax for the Northern Denison Trough.
• Analysis covers multiple Permian sandstone formations (Aldebaran Sandstone, Freitag Formation, Catherine Sandstone).

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.
