A thermal maturity framework dataset for Permian sandstone reservoirs in the Northern Denison Trough, Bowen Basin, Australia. It was created as part of the Queensland Government's ZeroGen CO2 Capture and Storage Project and is hosted by the Australian Ocean Data Network. The data includes vitrinite reflectance measurements and Rock-Eval analysis results from coals and shales.
Use Cases
- Calibrating thermal maturity models based on vitrinite reflectance (Rmax) and Rock-Eval Tmax data.
- Assessing CO2 storage potential in sandstone reservoirs based on described diagenetic effects on porosity and permeability.
- Studying the impact of depositional environments and marine flooding surfaces on vitrinite reflectance suppression.
- Estimating palaeotemperatures and burial history from vitrinite reflectance-depth profiles.
- Evaluating hydrocarbon generation potential of coals versus shales using Rock-Eval Hydrogen Index data.
Strengths
- Provides specific measured ranges for key maturity indicators: vitrinite reflectance (Rmax) from 0.55% to 0.93% and Rock-Eval Tmax from 421°C to 447°C.
- Includes analysis of error sources in palaeotemperature calculation, quantifying an equivalent temperature difference of approximately 19°C from a 0.2% Rmax difference.
- Data is contextualized within a specific geological study area (Northern Denison Trough) and project (ZeroGen CO2 Capture and Storage).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last updated date is 2026-06-16 21:56:23.305319.
