Browse Basin Petroleum Systems Analysis with Isotopic and Molecular Data

A dataset from the Australian Ocean Data Network redefines the petroleum systems of the Browse Basin offshore Western Australia. It collates molecular, isotopic, and biomarker data for wet gases and crude oils to analyze the origin and extent of four distinct petroleum systems. The work updates the basin's understanding, highlighting complex gas sourcing and biodegradation effects.

Use Cases

• Modeling hydrocarbon generation and migration based on defined petroleum systems and source rock affinities.
• Analyzing gas composition and origin based on molecular and isotopic datasets for wet gases.
• Assessing biodegradation and recharge effects in oil and gas accumulations like Cornea and Gwydion.
• Correlating crude oils with source rocks using biomarker and 13C/12C isotopic profiles.

Strengths

• Focuses on a major hydrocarbon province with quantified reserves, including the Ichthys accumulation with 12.8 Tcf gas and 527 mmbbl condensate.
• Integrates multiple data types, including molecular, isotopic, and biomarker datasets for a holistic analysis.
• Defines four distinct petroleum systems with specific source, reservoir, and geographic characteristics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; the description notes the basin's systems had not been updated for a decade prior to this work.
