Mean maximum vitrinite reflectance of coals ranges from 0.55% to 0.93%, with estimated maximum burial temperatures between 83°C and 125°C. This dataset, from the Australian Ocean Data Network, presents a thermal maturity framework for Permian sandstone reservoirs in the Northern Denison Trough, Australia, based on vitrinite reflectance and Rock-Eval analysis. The study was part of the Queensland Government's ZeroGen CO2 Capture and Storage Project, evaluating reservoir degradation factors.
Use Cases
- Modeling thermal maturity and burial history based on vitrinite reflectance (Rmax) values.
- Assessing CO2 storage potential of sandstone reservoirs using Rock-Eval parameters like Tmax and Hydrogen Index.
- Calibrating palaeotemperature calculations by analyzing suppression effects from perhydrous and subhydrous vitrinite.
- Evaluating hydrocarbon generation potential of coals and shales in specific stratigraphic intervals.
Strengths
- Vitrinite reflectance measurements span a defined range from 0.55% to 0.93% Rmax.
- Rock-Eval Tmax values are provided across the studied interval, ranging from 421°C to 447°C.
- Data is tied to a specific geological study and project (ZeroGen CO2 Capture and Storage Project).
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.
