Australian Petroleum Source Rock Geochemical Database

10 MB relational database contains organic geochemical data for petroleum source rock assessment. The majority of data originates from petroleum exploration wells drilled offshore and onshore Australia, with limited data from selected overseas areas. Company petroleum well completion reports are the major source of data.

Use Cases

• Predict thermal maturity using mean, minimum, and maximum vitrinite reflectance values alongside total organic carbon.
• Classify rock types based on percentages of alginite, exinite, vitrinite, and inertinite macerals.
• Analyze solvent extract composition by weight of saturated, aromatic, polar, and asphaltene components.
• Model elemental composition relationships using percentages of carbon, hydrogen, oxygen, sulphur, nitrogen, iron, and ash.
• Correlate basin, formation name, and age with geochemical parameters like TAI and SCI for regional assessments.

Strengths

• Database size is 10 MB, indicating a substantial collection of records.
• Contains detailed geochemical measurements including multiple vitrinite reflectance values and maceral percentages.
• Majority of data sourced from petroleum exploration wells, providing industry-relevant samples.

Limitations

• Limited data from overseas areas, suggesting a primary geographic focus on Australia.
• Specific row count, column count, and temporal coverage are unknown.
• Additional data like GC, GCMS, pyrolysis-GC, and stable isotopes are held outside the main database.
