Adavale Basin: Hydrocarbon Resource Assessment for Seven Play Intervals

Thirty-nine petroleum exploration wells form the basis for a systematic assessment of conventional and unconventional hydrocarbon resources in Queensland's Adavale Basin. The analysis evaluates twenty-five play elements across seven distinct chronostratigraphic sequences, from the Gumbardo to the Buckabie, using a data-driven, split-risking methodology. Risk maps generated from this work support the Australian Government's Trusted Environmental and Geological Information (TEGI) program, aiming to provide transparent baseline data for resource development and environmental planning.

Use Cases

• Identifying spatial risk variation for hydrocarbon plays based on well-point maps and split-risking methodology.
• Assessing resource potential for specific play intervals like the Log Creek or Cooladdi sequences.
• Supporting environmental baseline studies by providing trusted geological information for the TEGI program.
• Evaluating conventional and unconventional opportunities, including the known Gilmore gas discovery.

Strengths

• Assessment is based on a specific count of thirty-nine petroleum exploration wells.
• Systematic methodology evaluates twenty-five distinct play elements across seven defined sequences.
• Produced under the authoritative Trusted Environmental and Geological Information (TEGI) program by Geoscience Australia and CSIRO.

Limitations

• Considerable uncertainty exists in areas with sparse data due to reliance on well information and a lack of seismic coverage.
• Key metadata such as row count, specific columns, file size, and license information is absent from all platform entries.
• The description is truncated mid-sentence ('to indicate qua'), suggesting incomplete documentation.
