Australian Onshore Basin Seismic and Petroleum Systems Analysis

Geoscience Australia's Onshore Energy Security Program analyzed three frontier sedimentary basins from 2006-2011. The study interpreted deep seismic reflection profiles and conducted petroleum systems maturation modelling for the Arrowie, Georgina, and Darling Basins. It assessed hydrocarbon potential, including source rock maturity and basin architecture.

Use Cases

• Interpret deep seismic reflection profiles to map basin architecture and sequence boundaries in the Arrowie, Georgina, and Darling Basins.
• Apply petroleum systems maturation modelling to evaluate the maturity of Cambrian and Neoproterozoic source rocks for oil and gas generation.
• Analyze seismic data to characterize basin fill thickness, such as the ~3800 m section in the Arrowie Basin and the ~2800 m succession in the Georgina Basin.
• Correlate seismic sequence boundaries with major Neoproterozoic stratigraphic groups from the Adelaide Rift System.
• Assess geological risk factors like long preservation time and unroofing based on maturation modelling results for the Georgina Basin.

Strengths

• Analysis covers three distinct Australian sedimentary basins: Arrowie, Georgina (Burke River Zone), and Darling (Yathong Trough).
• Study integrates two primary methodologies: deep seismic reflection profile interpretation and petroleum systems maturation modelling.
• Provides quantified geological measurements, such as basin fill thickness of ~3800 m in the Arrowie Basin and ~2800 m in the Georgina Basin.

Limitations

• Data is presented in report formats (PDF, HTML) without underlying structured tabular or spatial datasets for direct computational analysis.
• Findings are based on a specific, concluded government program (2006-2011), and may not reflect the most recent exploration data.
• Geographic scope is limited to three specific basin areas, not a national-scale assessment of all onshore basins.
