Geoscience Australia Data provides geochemical analysis of gas-condensate petroleum systems in the Browse Basin, focusing on fluid properties like condensate-gas ratios and biomarker signatures. The dataset correlates four Mesozoic petroleum systems identified by geochemical fingerprints with specific dew point systems. It includes measurements such as gas dryness percentages, API gravity of condensates, and calculated vitrinite reflectance for maturity assessment.
Use Cases
- Classifying petroleum system families based on biomarker assemblages and carbon isotopic signatures described in the study.
- Modeling dew point pressure and condensate-gas ratio relationships for reservoir fluids as discussed in the analysis.
- Correlating source rock maturity (e.g., vitrinite reflectance) with fluid properties like gas dryness and API gravity.
- Mapping the distribution of terrestrial versus marine-influenced hydrocarbon sources using sterane and triterpane biomarkers.
Strengths
- Includes specific geochemical measurements such as gas dryness (91%), ideal CGRs (7-52 bbl/MMscf), and API gravity (47-53°).
- Defines distinct fluid families (W1_1BRO, W1_2BRO) based on molecular and isotopic signatures.
- Provides maturity indicators like calculated vitrinite reflectance (Rc) ranging from 0.77% to 1.18%.
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 require extraction for computational analysis.
