Abstract:

UKGEOS and Core Sample Analysis. Geomechanical testing was performed to determine triaxial compressional strength, tensile strength, frictional strength and permeability of sandstones, siltstones, mudstones and coals from eleven depth intervals within the GGC01 borehole, UK Geoenergy Observatories (UKGEOS), Glasgow, United Kingdom. Frictional strength tests were also performed on cuttings samples of sandstones, siltstones, mudstones and coals from the GGA08 borehole, Glasgow, United Kingdom. In total twenty-three tensile strength tests were performed on ten sampled intervals, and seven porosity measurements pre-and post-failure were taken. Nine triaxial compressive strength tests and twenty-one frictional strength tests were performed, with permeability measured both before and after failure or shear respectively. From compressive strength tests we also determined the Young’s modulus and Poisson’s ratio. Results of X-Ray Diffraction are also included in the dataset.

statement:

20mm x 40-70mm core plugs sampled from the GGC01 borehole were used for geomechanical testing in University of Liverpool's Rock Deformation Laboratory. All fabrics observed were sub-perpendicular to the drillcore axis so that maximum compressive stress in triaxial tests and tensile strengths are measured at 90° to these fabrics. Porosity was measured prior to testing using a helium pycnometer. In compressional experiments, cores were tested in a triaxial deformation apparatus. Samples were saturated with pore fluid at 2.5MPa and confining pressures were held at 6MPa. Permability was determined using the pulse-transient method. Tensile strength was measured on rock discs via a Brazilian test jig in a uniaxial press. Spare material was crushed to <125 microns and sheared between two porous metal plates to determine frictional strength. Crushed material was also used for XRD analyses.
