Stress-Dependent Permeability data, XRD Mineralogy, Porosity, Density for Glasgow Main Coal, mudstone and sandstone.
Stress-Dependent permeability data for samples of the Glasgow Main coal and the overlying mudstone and sandstone from the UKGEOS research borehole GGC01. Associated XRD mineralogy, Helium Porosity, bulk and matrix densities are also included. 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.

Data Quality
Cylindrical samples of 25.44mm diameter, and approximately 25.44mm length were manufactured from Glasgow Main coal, and the underlying mudstone and sandstone. Samples were manufactured in both bedding parallel and bedding-normal orientations, except in the coal, where no samples were successfully manufactured with the cylinder axis parallel to layering. After sample manufacture, each sample was dried to constant mass ( dm/dt < 0.01g/day) and was characterised in terms of helium porosity and density. X-Ray Diffraction was used to determine the mineralogy of these sample materials as volume percentages. The stress-dependent permeability was measured using the oscillating pore-pressure technique as described by Turner (1958); Kranz et al. (1990); Fischer (1992); Bernabe et al. (2006); Song and Renner (2007); McKernan et al. (2017). Argon gas was the pore fluid.
