Adavale Basin Hydrocarbon Resource Assessment with Seven Play Intervals

A 2022 assessment of conventional and unconventional hydrocarbon resources in the Adavale Basin of central Queensland. The dataset was produced by Geoscience Australia and CSIRO under the TEGI program, analyzing thirty-nine petroleum exploration wells and sequence stratigraphic data. It includes risk maps for seven chronostratigraphic play intervals and identifies twenty-five play elements.

Use Cases

• Generate hydrocarbon prospectivity maps based on the twenty-five identified play elements.
• Prioritize areas for energy exploration based on composite common risk segment maps.
• Assess unconventional hydrocarbon play potential in zones identified around the Gilmore area and Swaylands-1 well.
• Support environmental baseline studies using the transparent, trusted data from the TEGI program.

Strengths

• Analysis is based on thirty-nine petroleum exploration wells, providing a substantial foundation.
• Assessment covers seven distinct play intervals, offering a structured view of the basin's chronology.
• Methodology is explicitly data-driven, using well-point maps and a split-risking methodology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Reliance on well information is noted, with considerable uncertainty in areas of sparse data due to a lack of seismic coverage.
• Row count is unknown, which may limit suitability assessment.
