Canning Basin Crude Oil Biomarkers for Paleo-Depositional Environment Reconstruction

A study of diagnostic carotenoid-derived biomarkers from crude oils and source rocks in the large (~720,000 km²) Paleozoic Canning Basin. The data extends prior geochemistry work by Edwards et al. (2013) and Spaak et al. (2017, 2018), focusing on Ordovician, Devonian, and Carboniferous-sourced oils to clarify paleo-depositional environments and water stratification. Analysis was implemented by GeoMark Research and includes biomarkers like beta-carotane, paleorenieratane, and chlorobactane from specific wells such as Ungani, Blina, and Dodonea 1.

Use Cases

• Modeling paleo-depositional environments based on carotenoid biomarker distributions.
• Characterizing water column stratification (oxic vs. euxinic) using aromatic carotenoid signatures.
• Correlating oils to specific source rock intervals (Ordovician, Devonian, Carboniferous) based on biomarker fingerprints.
• Assisting petroleum exploration strategies by clarifying source rock formation and distribution.

Strengths

• Focuses on a large frontier petroleum province of approximately 720,000 km².
• Extends prior published geochemistry studies with new biomarker analysis.
• Includes analysis of oils from multiple specific wells (e.g., Ungani, Blina, Dodonea 1) across the basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF format, which may complicate direct computational analysis.
