Hydrocarbon Resource Assessment of the Adavale Basin with 7 Play Intervals

A 2022 assessment of conventional and unconventional hydrocarbon potential in the Adavale Basin, central Queensland. The dataset was generated by Geoscience Australia and CSIRO using 39 petroleum exploration wells and a data-driven, split-risking methodology. It identifies 25 play elements and seven chronostratigraphic sequences, producing risk maps to indicate prospectivity.

Use Cases

• Identify zones of hydrocarbon prospectivity based on interpreted play elements like reservoir, seal, and charge.
• Prioritize areas for energy exploration based on generated common risk segment maps.
• Assess carbon capture and storage opportunities using the basin's geological framework.
• Analyze spatial variation in resource risk using the split-risking methodology applied to well data.

Strengths

• Assessment is based on analysis of 39 petroleum exploration wells.
• Systematic methodology identified 25 distinct play elements and seven play intervals.
• Risk maps provide qualitative prospectivity for both conventional and unconventional resources.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Reliance on well information is noted, with considerable uncertainty in areas of sparse data.
• Column-level documentation is absent; field semantics must be inferred after download.
