Low CO₂ relative permeability in Bentheimer sandstone revealed by steady-state measurements and pore-scale imaging.

raw micro-ct images at fractional flow of 1 for CO2 and zero for brine

micro-ct image of the sample at all fractional flows used all sections stitched, merged and filtered using a non-local mean filter and also normalized to reduce noise.

images taken under 8Mpa pressure and 50 degrees C temperature

the raw images were processed using Avizo 3D 2023.2
