Conference Paper
Low-permeability geological seals may be compromised by the occurrence of fluid-conductive fault and fracture systems, which can potentially transmit fluids away from the storage reservoir. We performed a systematic laboratory-based investigation into the effect of surface roughness on the fluid flow properties of both natural rock and 3D-printed f...


Project (1)
Combining a variety of methods for an integrated assessment of flow in mudrocks and shales. At small scale (d<~2nm): use low pressure sorption (CO2, N2) and small angle neutron scattering (SANS) to determine surface area, pore size distribution and effective diffusion (via fractals); high pressure gas adsorption to determine gas storage capacity. At intermediate scale (d>~2nm<10μm): focused Ion Beam SEM in combination with SANS and N2 sorption to characterise pore structure; permeability tests on sample plugs. At large scale (d>10μm): Fracture hydraulic conductivity measurements and nano/μCT scanning on sample plugs. Pore-scale gas flow will be simulated on shale pore-network models that are constructed from characterisations to be obtained from FIB images and small angle scattering/gas adsorption measurements to perform mechanistic modelling with respect to pore geometry and topology and fluid transport mechanisms. The results can then be used to interpret laboratory flow measurements by numerical inversion on X-ray tomograms of small shale sample plugs.
