Geochemical Analysis of Gilmore Gas and Oil in the Adavale Basin, Queensland

A 1998 study by Boreham and de Boer analyzes the origin of dry gas and oil in the Gilmore Field. The research uses molecular and multi-element isotopic approaches to identify gas sources, including wet gas from Devonian source rocks and overmature methane. The dataset likely contains geochemical measurements supporting the analysis of reservoir compartmentalization and migration pathways.

Use Cases

• Identifying overmature gas sources based on isotopic signatures and nitrogen content described in the study.
• Modeling petroleum generation and migration pathways based on the concept of Devonian source rock reactivation.
• Correlating Devonian-sourced oils across different Australian basins using source-sensitive biomarkers and carbon isotopes.
• Assessing reservoir compartmentalization based on the distribution of overmature dry gas along the eastern margin of the Lissoy Sandstone.

Strengths

• Analysis is based on a specific field study (Gilmore Field) with identified source rocks like the Log Creek Formation and Cooladdi Dolomite.
• Employs a combination of molecular and multi-element isotopic approaches for source recognition.
• Provides specific maturity ranges, such as vitrinite reflectance of 1.4-1.6 per cent for wet gas and oil.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is derived from a 1998 publication; freshness should be verified for contemporary applications.
