Petroleum Source Analysis for Bowen and Surat Basins

A geochemical study analyzes 130 core samples from potential source rocks in the Bowen and Surat basins. Biomarker and stable carbon-isotope analysis identifies a pre-Jurassic, primarily Permian terrestrial source for petroleum, with details on maturation thresholds.

Use Cases

• Correlate petroleum samples to source rock facies using biomarker analysis data
• Model petroleum generation phases using vitrinite reflectance (Ro) thresholds from 0.65% to 1.05%
• Differentiate terrestrial versus marine source contributions via stable carbon-isotope analysis
• Assess liquid generation potential across lower delta plain and alluvial Permian coal facies

Strengths

• Analysis based on 130 core samples from source rocks
• Provides specific geochemical maturation thresholds (vitrinite reflectance from 0.65% to 1.05%)
• Data sourced from Geoscience Australia, an authoritative government organization

Limitations

• Data is presented in report formats (HTML, PDF), not as a structured, queryable table
• Sample size of 130 cores may limit granular spatial analysis across the entire basin area
• Temporal coverage and specific sample locations are not detailed in the provided input
