Adavale Basin Hydrocarbon Prospectivity Assessment with Risk Maps

A 2022 assessment of conventional and unconventional hydrocarbon resources in Queensland's Adavale Basin. Geoscience Australia and CSIRO analyzed 39 petroleum exploration wells and sequence stratigraphic data to evaluate seven play intervals. The analysis produced risk maps indicating qualitative prospectivity and identified two zones of unconventional hydrocarbon potential.

Use Cases

• Identify areas for future hydrocarbon exploration based on the composite common risk segment maps.
• Assess unconventional resource potential in the two identified zones around the Gilmore and Swaylands-1 areas.
• Guide environmental and resource development policy using the transparent, trusted baseline data.
• Prioritize geological and geophysical data acquisition in areas of sparse data and high uncertainty.

Strengths

• Analysis is based on 39 petroleum exploration wells, providing a direct data foundation.
• Systematic assessment of seven distinct play intervals from the Gumbardo to Buckabie sequences.
• Risk maps were generated for each play using a split-risking methodology for play chance and repeatability.

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 driven by the sparsity of seismic data, which may limit spatial understanding.
