Adavale Basin Hydrocarbon Resource Assessment with 7 Play Intervals and 25 Play Elements

A 2022 assessment of conventional and unconventional hydrocarbon potential in Queensland's Adavale Basin, conducted by Geoscience Australia and CSIRO. The analysis is based on 39 petroleum exploration wells and identifies seven play intervals and 25 play elements, generating qualitative risk maps. The work was presented at the Central Australian Basins Symposium IV.

Use Cases

• Identify zones of conventional hydrocarbon prospectivity based on composite common risk segment maps.
• Assess unconventional hydrocarbon play potential in two identified zones around the Gilmore and Swaylands-1 areas.
• Guide energy exploration policy using data-driven, split-risking methodology for play elements.
• Evaluate carbon capture and storage opportunities based on the basin's geological and stratigraphic framework.

Strengths

• Assessment is based on analysis of 39 existing petroleum exploration wells.
• Systematically evaluates seven distinct play intervals and 25 play elements.
• Methodology is explicitly data-driven, using ArcGIS 'Player' extension for analysis.

Limitations

• Considerable uncertainty exists in areas of sparse data, as the methodology relies heavily on well information due to sparse seismic coverage.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
