A sequence of rocks pyrolysed in the laboratory under nitrogen at temperatures in the range 310-370°C were analyzed using small angle neutron scattering (SANS). Geoscience Australia Data published this dataset, which demonstrates a technique for determining the onset of hydrocarbon transport in shaly source rocks. The data includes observations from both laboratory-pyrolysed rocks and a natural maturity sequence from the same location.
Use Cases
- Modeling the onset of primary hydrocarbon migration based on SANS contrast variation.
- Correlating laboratory pyrolysis results with natural rock maturity sequences.
- Analyzing pore space invasion by bitumen during hydrocarbon generation.
Strengths
- Data includes a controlled laboratory sequence with pyrolysis temperatures ranging from 310-370°C.
- Findings are validated against a natural maturity sequence of source rocks from the same location.
- The description specifies the organic matter type as marine Type II, present at several percent.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
