Origins of non-tectonic fractures in shale

Q Meng, F Hao, J Tian - Earth-Science Reviews, 2021 - Elsevier
Natural fractures are widespread in shales in sedimentary basins and can significantly
increase the bulk permeability and enhance fluid flow, which are thereby considered to be a …

Quantifying the anisotropy and tortuosity of permeable pathways in clay-rich mudstones using models based on X-ray tomography

NR Backeberg, F Iacoviello, M Rittner, TM Mitchell… - Scientific reports, 2017 - nature.com
