Hydrocarbon Generation Kinetics for the Ordovician Goldwyer Formation, Canning Basin

Pyrolysis and bulk kinetic studies investigate the hydrocarbon generation potential of marine organic-rich rocks from the Middle Ordovician Goldwyer Formation. Results imply the upper Goldwyer Sequence I contains oil-prone Type I kerogen, while the lower Sequence III comprises Type II/III kerogen. The dataset provides basin-specific kinetic inputs for burial history modeling on the Broome Platform.

Use Cases

• Modeling hydrocarbon generation timing and transformation ratios based on pyrolysis-derived kinetic parameters.
• Comparing source rock quality and organofacies between different stratigraphic sequences (Goldwyer I vs. III).
• Calibrating burial history models with basin-specific kinetic data for the Broome Platform.
• Assessing the potential for paraffinic vs. paraffinic-naphthenic-aromatic oil generation from calcareous mudstones.

Strengths

• Data is derived from Rock Eval pyrolysis and pyrolysis gas chromatography (Py-GC) analyses.
• Kinetic parameters are provided for two distinct kerogen types (Type I and Type II/III) across different sequences.
• Includes estimated hydrocarbon generation temperature intervals for a constant geological heating rate of 3°C/Ma.

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 study area in the Canning Basin.
