Browse Basin Petroleum Systems with Geochemical and Reserve Data

The super-giant Ichthys gas accumulation is estimated to host 12.8 trillion cubic feet of gas and 527 million barrels of condensate. This dataset collates molecular, isotopic, and biomarker data to redefine four petroleum systems in Australia's Browse Basin, a major LNG province. The data was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Modeling hydrocarbon generation and migration based on molecular and isotopic datasets.
• Assessing gas and condensate reserves based on detailed accumulation estimates like those for Ichthys and Brecknock.
• Correlating source rocks with petroleum fluids based on biomarker and isotopic profiles.
• Analyzing the impact of biodegradation and recharge on oil and gas accumulations, as described for the Yampi Shelf.

Strengths

• Includes specific reserve estimates for major accumulations, such as 12.8 Tcf of gas at Ichthys.
• Defines four distinct petroleum systems with detailed geochemical sourcing profiles.
• Collates multiple data types including molecular, isotopic, and biomarker datasets.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific offshore basin study area.
