Geomechanical And Petrophysical Test Results From Six Birrindudu Basin Drill Holes

Sixteen samples underwent unconfined compressive strength and ultrasonic tests, while thirty-two samples were analyzed for grain density, porosity, and permeability. Data originates from laboratory testing on Paleoproterozoic to Mesoproterozoic cores from six drill holes in the Birrindudu Basin, performed by CSIRO from January to June 2025.

Use Cases

• Analyze unconfined compressive rock strength results across different core samples to assess rock stability.
• Correlate ultrasonic measurement data with dry bulk density from XCT scans to model internal rock textures.
• Evaluate gas porosity and permeability test results from 32 samples for reservoir characterization.
• Compare geomechanical properties like compressive strength with petrophysical data like grain density from the 48 total tested samples.

Strengths

• Data includes results from 48 distinct physical laboratory tests on rock core samples.
• Testing was performed at a specialized CSIRO Geomechanics and Geophysics Laboratory.
• Covers six different drill holes, providing a spatial spread within the Birrindudu Basin.

Limitations

• Limited sample size of 48 total tested specimens may not represent full basin heterogeneity.
• Primary data is delivered in PDF and ZIP formats, requiring manual extraction for analysis.
• Temporal coverage is limited to a single testing period from January to June 2025.
