The Otway and Gippsland Basins offshore Australia were surveyed during April/May 1988 by the BMR research vessel 'Rig Seismic'. Light hydrocarbon gases (C1-C6) were measured in sediments at 342 locations on the continental shelf and slope. Thermogenic hydrocarbons were identified in near-surface sediments at forty-two locations.
Use Cases
- Identify thermogenic hydrocarbon sources based on sediment gas measurements.
- Analyze hydrocarbon source type and maturity based on wet gas content ratios.
- Model hydrocarbon migration pathways based on gas concentration patterns and faulting.
- Integrate geochemical data with thermal maturation modeling to locate principal source rocks.
Strengths
- 342 sampling locations provide spatial coverage of the continental shelf and slope.
- Gas measurements include C1-C6 hydrocarbons, allowing for compositional analysis.
- Results are integrated with thermal maturation modeling and well data.
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 survey areas.
