X-ray tomography imaging of shale microstructures: A review in the context of multiscale correlative imaging
Sign Up to like & getrecommendations! Published in 2020 at "International Journal of Coal Geology"
DOI: 10.1016/j.coal.2020.103641
Abstract: Abstract Shale microstructure determines hydrocarbon reserves and productivity. However, despite its high economic importance, the shale microstructure remains poorly understood. This is largely due to the complex pore space configuration in shale, and associated heterogeneity… read more here.
