Adavale Basin Hydrocarbon Resource Assessment with 7 Play Intervals

Geoscience Australia and CSIRO produced a multidisciplinary resource assessment of the Adavale Basin in central Queensland. The analysis used data from thirty-nine petroleum exploration wells to assess seven play intervals for conventional and unconventional hydrocarbon potential, including the Gilmore gas discovery. This abstract was presented at the 2022 Central Australian Basins Symposium IV.

Use Cases

• Generate qualitative prospectivity risk maps based on the twenty-five identified play elements.
• Identify zones for future hydrocarbon exploration based on the split-risking methodology applied to well-point data.
• Guide policy decisions for resource development using the composite common risk segment maps.
• Assess carbon capture and storage opportunities based on the basin's geological and environmental information.

Strengths

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

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.
