Origin of Gilmore Gas and Oil in the Adavale Basin, Central Queensland

A 1998 study published in The APPEA Journal analyzes the origin of dry gas and oil in the Gilmore Field. The research uses a molecular and multi-element isotopic approach to identify sources from Devonian rocks and a deep, overmature source. The dataset, hosted by the Australian Ocean Data Network, presents findings on reservoir compartmentalisation and migration pathways.

Use Cases

• Modeling hydrocarbon generation and expulsion based on described vitrinite reflectance values (1.4-1.6%) and Cretaceous reactivation events.
• Identifying overmature gas sources based on isotopic signatures and high nitrogen content mentioned in the description.
• Correlating Devonian-sourced oils across basins based on described biomarker and carbon isotope commonalities.
• Assessing reservoir compartmentalisation and migration pathways based on the described distribution of overmature gas.

Strengths

• Study is peer-reviewed and published in a recognized industry journal (The APPEA Journal).
• Analysis employs a multi-method approach combining molecular and isotopic data as described.
• Provides specific geochemical parameters, such as vitrinite reflectance of 1.4-1.6%.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
