Australian Onshore Basin Petroleum Potential from Seismic Data and Modelling

The Onshore Energy Security Program, funded from 2006 to 2011, generated precompetitive geoscience data for frontier basins. Geoscience Australia interpreted deep seismic reflection profiles and conducted petroleum systems maturation modelling for the Arrowie, Georgina, and Darling Basins. The analysis includes basin architecture details, such as a maximum thickness of ~3800 meters in the Arrowie Basin, and assessments of source rock maturity for hydrocarbon generation.

Use Cases

• Assess basin architecture and stratigraphy based on interpreted deep seismic reflection profiles.
• Model petroleum system maturity and hydrocarbon generation potential for Cambrian and Neoproterozoic source rocks.
• Evaluate exploration risks, such as preservation time and trap formation, based on maturation modelling results.
• Identify areas for potential unconventional hydrocarbon exploration based on evidence of bitumen in historical wells.

Strengths

• Data originates from a five-year government-funded program (2006-2011) providing precompetitive assessments.
• Includes specific geological measurements, such as a basin thickness of ~3800 meters in the Arrowie Basin and a width of ~65 km for the Georgina Basin zone.
• Integrates two analysis methods: seismic reflection interpretation and petroleum systems maturation modelling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Primary file formats are PDF and HTML, which may require extraction for computational analysis.
