Ashmore Platform Natural Seep Study: Hydrocarbon Evidence from the Bonaparte Basin

Geoscience Australia Data hosts a study establishing hydrocarbon charge to the Ashmore Platform in the Bonaparte Basin, Australia. The 2017 paper by Stalvies et al. describes an integrated study combining remote sensing, geophysical, acoustic, photographic, and geochemical techniques. It identified three areas of seepage, with geochemical data confirming the presence of thermogenic liquid hydrocarbons.

Use Cases

• Assessing hydrocarbon migration pathways based on identified natural seep locations
• Reducing exploration charge risk for the Ashmore Platform based on geochemical evidence
• Correlating seep isotopic compositions with known source rock formations like the Lower Cretaceous Echuca Shoals Formation
• Integrating remote sensing and geophysical data for basin-scale seep detection

Strengths

• Integrated study combining multiple techniques: remote sensing, geophysical, acoustic, photographic, and geochemical
• Geochemical data confirms thermogenic liquid hydrocarbons with isotopic compositions matching a known source formation
• Identified three specific areas of seepage, 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
• Data may reflect geographic bias inherent to the specific study area
