Geochemistry of Dew Point Petroleum Systems in the Browse Basin, Australia

A geochemical analysis of Mesozoic petroleum systems in Australia's Browse Basin, published by Geoscience Australia. The dataset correlates four geochemically distinct petroleum systems with dew point gas-condensate fluids. It includes specific measurements such as gas dryness percentages (91%), condensate-gas ratios (7-52 bbl/MMscf), and API gravity values (47-53°).

Use Cases

• Correlating source rock origin with fluid composition based on biomarker assemblages like C29 sterane and C19 tricyclic triterpane.
• Modeling dew point pressure and condensate-gas ratio relationships for reservoir engineering.
• Assessing thermal maturity of hydrocarbon accumulations using calculated vitrinite reflectance values (e.g., 0.77% to 1.18%).
• Classifying petroleum system families using molecular and carbon isotopic signatures of condensates.

Strengths

• Includes specific geochemical measurements: gas dryness (91%), ideal CGRs (7-52 bbl/MMscf), and API gravity (47-53°).
• Identifies distinct petroleum system families (e.g., W1_1BRO, W1_2BRO) based on biomarker and isotopic data.
• Correlates geological formations (e.g., Plover Formation) with fluid properties and maturity levels.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may require extraction and structuring for analysis.
