Goldwyer Formation Hydrocarbon Generation Kinetics

The Canning Basin in Western Australia is the focus of this dataset on the hydrocarbon generation potential of marine organic-rich rocks from the Middle Ordovician Goldwyer Formation. It contains results from pyrolysis and bulk kinetic studies, detailing kerogen types, organofacies, and estimated generation temperatures for different geological sequences. The data provides basin-specific kinetic inputs for modeling petroleum systems and evaluating source rock variability.

Use Cases

• Calibrating burial history models using basin-specific kinetic parameters for the Goldwyer Formation.
• Assessing source rock quality and generative potential based on kerogen type (Type I vs. Type II/III) and organofacies.
• Estimating hydrocarbon generation windows (e.g., 145–170°C for Sequence I) for thermal maturity modeling.
• Evaluating the variability in oil and gas proneness between the upper Goldwyer Sequence I and lower Sequence III.

Strengths

• Data is derived from specific analytical methods: Rock Eval pyrolysis and pyrolysis gas chromatography (Py-GC).
• Provides concrete, basin-specific kinetic parameters for two distinct geological sequences (Goldwyer I and III).
• Includes estimated temperature ranges for hydrocarbon generation (e.g., 145–170°C for Type I kerogen).

Limitations

• Key structural metadata is missing: column names, row count, and file size are unknown.
• License and author information are not provided, limiting clarity on reuse permissions.
• The dataset's format is listed only as HTML, which may not be ideal for direct quantitative analysis.
