Adavale Basin 1D Burial 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 were constructed by the Australian Ocean Data Network using open file well data and presented at the 2023 Australian Exploration Geoscience Conference. They estimate hydrocarbon generation potential and identify specific geological formations as targets for unconventional gas exploration.

Use Cases

• Predict source rock maturity and hydrocarbon generation timing using modeled temperature and vitrinite reflectance data.
• Assess the quality of formations like the Log Creek Formation and Bury Limestone using Total Organic Carbon (TOC) and pyrolysis data features.
• Calibrate basin thermal models with bottom hole temperature and measured vitrinite reflectance data from wells.
• Evaluate potential trapping mechanisms for hydrocarbons using features for facies, regional seals, and localised deposits.
• Model paleo-heat flow and source rock maturation history using assigned boundary conditions for paleo-surface temperature and paleo-water depth.

Strengths

• Nine distinct 1D models provide multiple data points for analysis.
• Models are calibrated using concrete bottom hole temperature and vitrinite reflectance measurements.
• Analysis identifies specific target formations (Log Creek Formation, Bury Limestone) with supporting geochemical data.

Limitations

• Sample size is limited to nine models, which may not capture full basin heterogeneity.
• Underlying well data and specific model parameters are not provided in the dataset.
• Models are based on existing open file data which may have inherent gaps or inconsistencies.
