Hydrocarbon Seepage Study for the Ashmore Platform, Bonaparte Basin

A natural seeps study integrates remote sensing, geophysical, acoustic, photographic, and geochemical techniques to investigate hydrocarbon migration. The research identified three areas of seepage on the southern flank of the Ashmore Platform and provided geochemical evidence of thermogenic liquid hydrocarbons. The dataset likely contains findings from this integrated survey, published in Marine and Petroleum Geology in 2017.

Use Cases

• Assessing hydrocarbon charge risk for the Ashmore Platform based on evidence of active natural seepage.
• Correlating seep geochemistry with known source rocks based on isotopic compositions matching the Echuca Shoals Formation.
• Mapping persistent versus episodic hydrocarbon leakage based on remote sensing and acoustic survey data.
• Modeling lateral hydrocarbon migration pathways from the Caswell Sub-basin based on seep locations.

Strengths

• Integrated data from multiple techniques: remote sensing, geophysical, acoustic, photographic, and geochemical.
• Geochemical data demonstrates the presence of thermogenic liquid hydrocarbons with specific isotopic signatures.
• Identified three distinct seepage areas, characterizing one as persistent and two as episodic.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-05-14.
