Geomechanical Properties of UKGEOS Glasgow Borehole Rock Samples

Twenty-three tensile strength tests, nine triaxial compressive strength tests, and twenty-one frictional strength tests were performed on sandstones, siltstones, mudstones, and coals from the GGC01 and GGA08 boreholes in Glasgow, UK. The dataset includes results for permeability, Young’s modulus, Poisson’s ratio, and X-Ray Diffraction analysis, compiled by the British Geological Survey.

Use Cases

• Analyze the relationship between rock type (sandstone, siltstone, mudstone, coal) and measured triaxial compressional strength for geomechanical modeling.
• Model fracture fluid flow by correlating pre- and post-failure permeability measurements with tensile strength test results.
• Assess frictional stability for geothermal applications using frictional strength data from cuttings and core samples.
• Calculate elastic parameters for reservoir simulation using Young’s modulus and Poisson’s ratio derived from compressive strength tests.
• Characterize mineral composition's influence on geomechanical properties using included X-Ray Diffraction results.

Strengths

• Includes 21 frictional strength tests and 23 tensile strength tests, providing a basis for statistical analysis of rock strength.
• Contains seven porosity measurements taken both before and after failure, enabling direct analysis of failure impact.
• Data originates from two specific boreholes (GGC01 and GGA08) within the UKGEOS Glasgow observatory, providing precise spatial context.

Limitations

• Sample size is limited to specific intervals from two boreholes, which may not represent the full heterogeneity of the geological formation.
• The dataset lacks explicit row or column counts, making its overall scale and structure uncertain for large-scale modeling.
• Data is focused on a specific geographic location (Glasgow, UK), limiting direct applicability to other geological settings.
