Otway Basin Palynological Sample Data and Reports

Geoscience Australia's 2002-2004 project compiled new and revised palynological data for petroleum prospectivity analysis. The record contains data for over 200 new samples from 14 wells and revised data for 18 wells. Data includes consultant reports and standardized CSV files.

Use Cases

• Refine regional chronostratigraphic frameworks using standardized palynological taxonomy and well sample data.
• Correlate biozonations across the basin by analyzing fossil pollen and spore data from specific well samples.
• Support integrated petroleum systems analysis with updated age-control data from over 200 new samples.
• Conduct quality assurance on biostratigraphic interpretations by comparing original and revised data files.

Strengths

• Data from over 200 new samples provides a substantial update.
• Standardized taxonomy across revised files ensures consistency.
• Coverage includes 32 distinct wells (14 new, 18 revised) for basin-wide analysis.

Limitations

• Sample size is moderate, focused on 32 selected wells rather than the entire basin.
• Original data formats (wmf, dex) are outdated and require conversion.
• Temporal coverage of the core data collection is from a 2002-2004 project.
