Geoscience Australia conducted a multi-disciplinary study of the Browse Basin offshore Northwest Australia, analyzing seven Cretaceous supersequences from the late Tithonian to Maastrichtian. The study integrated updated biostratigraphy, seismic stratal geometry, facies interpretations, and geochemical analyses to identify three main Cretaceous stratigraphic play types and four Mesozoic petroleum systems. The regional deposition of Permo-Carboniferous, Triassic, Jurassic, and Cenozoic successions was mapped to constrain the burial history model.
Use Cases
- Model hydrocarbon generation potential based on burial history modelling of Jurassic and Lower Cretaceous supersequences.
- Identify and high-grade areas with increased liquids potential using sequence stratigraphy and structural framework analysis.
- Correlate hydrocarbon fluids with source rocks using molecular and stable carbon and hydrogen isotopic signatures.
- Analyze seal quality and thickness for basin margin plays in the K10-K40 supersequences.
- Map the distribution of gross depositional facies using supersequence cross-sections and palaeogeographic maps.
Strengths
- Study covers seven Cretaceous supersequences (K10-K60) from late Tithonian to Maastrichtian.
- Analysis identifies three main Cretaceous stratigraphic play types: basin-margin, clinoform topset, and submarine fan.
- Geochemical fingerprinting enabled the identification of four Mesozoic petroleum systems.
- Regional mapping includes Permo-Carboniferous, Triassic, Jurassic, and Cenozoic successions.
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 Browse Basin region.
