Gilmore Gas and Oil Geochemical Analysis, Adavale Basin, Queensland

Adavale Basin in central Queensland contains geochemical data on the origin of gas and oil from the Gilmore Field. The dataset likely includes molecular and multi-element isotopic measurements used to identify overmature dry gas and Devonian-sourced wet gas and oil. The data is sourced from a 1998 study published in The APPEA Journal and aggregated by Geoscience Australia.

Use Cases

• Identify overmature dry gas sources based on molecular and isotopic data mentioned in the description.
• Model petroleum generation and migration pathways based on concepts of Devonian source rock reactivation.
• Correlate Devonian-sourced oils across Australian basins using source-sensitive biomarkers and carbon isotope composition.
• Assess reservoir compartmentalization and gas displacement based on nitrogen content and isotopic signatures.

Strengths

• Data is derived from a peer-reviewed journal article with a specific DOI (10.1071/AJ97019).
• Analysis combines molecular and multi-element isotopic approaches, as described.
• Study provides specific maturity ranges (vitrinite reflectance of 1.4-1.6%) and identifies likely source rock formations.

Limitations

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