Petrel Sub-basin Study: Geohistory and Petroleum Systems Analysis

The 1995-1996 study by the Australian Geological Survey Organisation (AGSO) aimed to understand the stratigraphic and structural development of the Petrel Sub-basin on Australia's North West Shelf. It defines the nature and age of basement elements, basin-fill events, and tectonic evolution. The analysis specifically determines factors controlling the development and distribution of the basin's petroleum systems.

Use Cases

• Modeling basin evolution based on defined stratigraphic and structural history.
• Assessing petroleum system potential using factors controlling hydrocarbon occurrence.
• Planning exploration strategies by understanding the influence of major basement elements.
• Interpreting seismic data within the context of the study's geohistory framework.

Strengths

• Study conducted by a national geological survey organization (AGSO), suggesting authoritative methodology.
• Cross-platform presence on data.gov.au indicates recognized importance and persistence.
• Focus is specific, targeting the Petrel Sub-basin's geohistory and petroleum systems.

Limitations

• Core data columns and row/size metrics are completely unknown across all sources.
• Metadata for license, author, and precise data format is consistently missing.
• The dataset's freshness is unclear; the study is from 1995-1996, though metadata records were updated in 2026.
