Australia's Onshore Sedimentary Basins: Seismic Data and Petroleum Systems Modelling

Australian onshore sedimentary basins, including the Arrowie, Georgina, and Darling Basins, are assessed for hydrocarbon potential. The data includes interpretations of deep seismic reflection profiles and petroleum systems maturation modelling from a government-funded program between 2006 and 2011. The analysis provides details on basin architecture, stratigraphy, and the maturity of potential source rocks.

Use Cases

• Assess hydrocarbon prospectivity based on interpreted basin architecture and seismic stratigraphy.
• Model petroleum system maturity and hydrocarbon generation timing using maturation modelling results.
• Evaluate geological risks for exploration, such as trap preservation times and unroofing events.
• Plan future exploration strategies, including for unconventional hydrocarbons, based on evidence of past hydrocarbon systems.

Strengths

• Includes specific geological measurements, such as basin thicknesses of ~3800m and ~2800m.
• Provides analysis for three distinct basins (Arrowie, Georgina, Darling) with separate geological interpretations.
• Links seismic data interpretation to petroleum systems modelling for an integrated assessment.

Limitations

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