Geoscience Australia conducted a multi-disciplinary reassessment of hydrocarbon prospectivity in the Browse Basin offshore Northwest Australia. The study analyzed Cretaceous supersequences K10–K60, integrating sequence stratigraphy, structural framework, biostratigraphy, well logs, seismic data, and geochemical analyses of source rocks and fluids. The work identified three main Cretaceous stratigraphic play types and four Mesozoic petroleum systems through regional petroleum systems modeling.
Use Cases
- Model hydrocarbon generation potential based on burial history modeling of Jurassic and Lower Cretaceous supersequences.
- Identify and correlate petroleum systems based on geochemical fingerprinting of fluids and source rocks described.
- Evaluate reservoir and seal pair spatial relationships based on the analyzed sequence stratigraphy and structural framework.
- Map play fairways and assess prospectivity for basin-margin, clinoform topset, and submarine fan plays mentioned in the description.
Strengths
- Study integrates multiple disciplines including sequence stratigraphy, structural framework analysis, biostratigraphy, and geochemistry.
- Analysis covers seven Cretaceous supersequences from the late Tithonian to Maastrichtian (K10–K60).
- Identifies three main Cretaceous stratigraphic play types and four Mesozoic petroleum systems.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF and HTML formats, which may require extraction for quantitative analysis.
