Jurassic Sediment Architecture And Source Rock Analysis For Browse Basin

A multi-disciplinary study integrating sequence stratigraphy, palaeogeography, and geochemical data to map Jurassic to earliest Cretaceous source rocks in the Browse Basin. The analysis identifies primary source rocks for major gas and condensate accumulations, including the Ichthys and Prelude LNG fields. The dataset was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Correlate specific source rock formations like the Plover Formation (J10-J20) with gas accumulations on the Scott Reef Trend using sequence stratigraphy data.
• Model the depositional environment of Late Jurassic J30-K10 shales in rift settings to predict wet gas potential in the Brewster Member sandstone.
• Analyze geochemical composition data from the Heywood Graben to compare its petroleum system to the southern Bonaparte Basin, as seen in the Crux accumulation.

Strengths

• Study integrates multiple geological disciplines including sequence stratigraphy and geochemistry.
• Analysis covers a defined geological time range from the Jurassic to the earliest Cretaceous.
• Findings are directly linked to major, known hydrocarbon accumulations like Ichthys and Prelude.

Limitations

• Underlying data columns and sample sizes are not specified.
• Primary data format is PDF, limiting direct computational analysis without extraction.
• Geographic focus is restricted to the Browse Basin, limiting broader regional applicability.
