Adavale Basin 1D Burial and Thermal History Models for Hydrocarbon Potential

Nine 1D burial thermal and petroleum generation history models investigate Devonian source rock maturity in the Adavale Basin. The models, constructed using open file well data, provide estimates of hydrocarbon generation potential and maturation timing. Total organic carbon (TOC) content and pyrolysis data identify the Log Creek Formation and Bury Limestone as primary targets.

Use Cases

• Calibrate basin-scale thermal models using bottom hole temperature and measured vitrinite reflectance data from nine 1D models.
• Assess source rock quality and kerogen type by analyzing rock parameters including facies, temperature, and organic geochemistry/petrology.
• Model hydrocarbon generation timing and migration pathways using paleo-heat flow, paleo-surface temperature, and paleo-water depth boundary conditions.
• Evaluate unconventional gas potential in the Log Creek Formation and Bury Limestone based on maturity and Total Organic Carbon (TOC) indicators.

Strengths

• Nine distinct 1D models provide multiple data points for basin analysis.
• Models are calibrated with measured geophysical data, including bottom hole temperature and vitrinite reflectance.
• Analysis identifies specific geological formations (Log Creek, Bury Limestone, Buckabie) with source rock potential.

Limitations

• Limited to nine modeled well locations, offering sparse spatial coverage of the basin.
• Data is derived from modeling and interpretation of existing reports, not direct new measurements.
• Sample data and underlying tabular data (rows, columns) are unavailable for direct statistical analysis.
