Adavale Basin Hydrocarbon Resource Assessment with 7 Play Intervals

The Adavale Basin in central Queensland contains a sedimentary record from the Early Devonian to Late Devonian/Early Carboniferous. Geoscience Australia and CSIRO assessed conventional and unconventional hydrocarbon potential across seven play intervals using data from thirty-nine petroleum exploration wells. This data-driven assessment, presented in 2022, generated risk maps to indicate qualitative prospectivity for future energy exploration and carbon capture opportunities.

Use Cases

• Identify zones of unconventional hydrocarbon play potential based on the two identified areas mentioned in the description.
• Assess spatial variation in risk for play elements like reservoir and seal using the split-risking methodology described.
• Guide energy exploration policy by using the composite common risk segment maps outlining proven and potential play areas.
• Prioritize areas for future geological and geophysical data collection based on the identified areas of sparse data and uncertainty.

Strengths

• Assessment is based on data from thirty-nine petroleum exploration wells.
• Systematic analysis covers seven distinct chronostratigraphic play intervals.
• Methodology identified twenty-five play elements, such as reservoir, seal, and charge.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Reliance on well information is noted due to sparsity of seismic data, which may introduce uncertainty.
