Hydrocarbon Resource Assessment of the Adavale Basin in Central Queensland

A 2022 assessment of conventional and unconventional hydrocarbon resources in the Adavale Basin, central Queensland, conducted by Geoscience Australia and CSIRO. The analysis used data from thirty-nine petroleum exploration wells and identified seven play intervals and twenty-five play elements. Results include risk maps outlining proven and potential hydrocarbon zones, including the Gilmore gas discovery.

Use Cases

• Generate qualitative prospectivity maps based on the described split-risking methodology.
• Identify zones for conventional and unconventional hydrocarbon exploration based on the twenty-five defined play elements.
• Guide energy policy and prioritise exploration areas using the composite common risk segment maps.
• Assess geological uncertainty in areas of sparse data, as noted in the description.

Strengths

• Analysis is based on data from thirty-nine petroleum exploration wells.
• Assessment covers seven distinct play intervals defined by palynology.
• Methodology is explicitly data-driven rather than model-driven.

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.
• The reliance on well information is noted as a source of uncertainty due to sparse seismic data.
