Abstract:

A brief description of ten core plug samples collected from borehole GGC01 (Glasgow, United Kingdom) is provided, as well as for twelve 15-50 g cuttings samples from 1m intervals within borehole GGA08. Samples were also collected from borehole GGA02 but not used for further analyses. Data comprise results from geomechanical tests, permeability and porosity measurements, and X-Ray Diffraction analyses performed on drillcore samples of sandstones, siltstones, mudstones and coals from eleven depth intervals within the GGC01 borehole. Geomechanical data include triaxial compressional strength, tensile strength, and frictional strength. Frictional strength data was also collected for cuttings samples of sandstones, siltstones, mudstones and coals from the GGA08 borehole. 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. Samples and data are derived from the UK Geoenergy Observatories Programme funded by the UKRI Natural Environment Research Council and delivered by the British Geological Survey.

statement:

Core plugs, 19.75mm in diameter, were cut to lengths appropriate for rock deformation laboratory tests (Paterson & Wong, 2005; ASTM D7012-14, 2014; ASTM D3967-16, 2016). Specimens were dried at ~30 °C for >24 hours prior to any testing. Samples were axially compressed in a triaxial deformation apparatus at the University of Liverpool (Faulkner & Armitage, 2013). Tensile strength experiments were conducted using a uniaxial press and a Brazilian test jig. X-Ray Diffraction (XRD) Analyses were performed on eleven samples of crushed core material from the GGC01 borehole. Sample material was prepared using a mill crusher and agate ball crusher so that a size fraction of <125 µm was obtained for each test sample. Porosity of each GGC01 core plug sample was measured using a Quantochrome Multipycnometer, and permeability (k) was determined using the pulse-transient method (Brace et al., 1968).
