A 1998 study by Boreham and de Boer analyzes the dual origin of gas in the Gilmore Field, sourced from both wet gas associated with oil and overmature methane. The research uses molecular and multi-element isotopic data to characterize the gas and identify Devonian source rocks. It suggests a previously undervalued deep gas source play may be widespread in Australian basins.
Use Cases
- Modeling hydrocarbon generation and expulsion based on vitrinite reflectance values of 1.4-1.6%
- Identifying reservoir compartmentalization based on isotopic data suggesting dry gas migration pathways
- Evaluating the potential for deep overmature gas sources in other basins based on the described play concept
- Correlating Devonian-sourced oils across basins based on biomarker and carbon isotope composition
Strengths
- Specific vitrinite reflectance maturity range (1.4-1.6%) is provided for the wet gas and oil
- Identifies three specific potential source rock formations: Log Creek Formation, Lissoy Sandstone algal shales, and Cooladdi Dolomite
- Analysis employs a combination of molecular and multi-element isotopic approaches
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 data_gov_au
