Statement

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.
