Adavale Basin Hydrocarbon Resource Assessment with 7 Play Intervals

Geoscience Australia and CSIRO assessed conventional and unconventional hydrocarbon potential in Queensland's Adavale Basin. The analysis used data from 39 petroleum exploration wells and identified 25 play elements across seven chronostratigraphic sequences. Results include risk maps outlining proven and potential resource zones, supporting the Australian Government's TEGI program.

Use Cases

• Identify zones for conventional hydrocarbon exploration based on composite common risk segment maps.
• Assess unconventional hydrocarbon play potential in the Gilmore and Swaylands-1 areas.
• Guide resource development policy using the data-driven, split-risking methodology.
• Prioritize areas for future geological and geophysical data acquisition based on identified uncertainty.

Strengths

• Assessment is based on data from 39 petroleum exploration wells.
• Systematic evaluation covers 7 distinct play intervals and 25 play elements.
• Methodology is explicitly data-driven rather than model-driven.

Limitations

• Considerable uncertainty exists in areas of sparse data, as noted in the description.
• Reliance on well information is driven by sparsity of seismic data across the basin.
• Column-level documentation is absent; field semantics must be inferred after download.
