X-ray imaging with measurements of CO2 and brine relative permeability, curvature and capillary pressure in a Bentheimer sandstone: Evidence for low gas relative permeability at reservoir conditions.

micro-ct image of the sample at fractional flow 1 of CO2 and 0 of brine all sections stitched ,merged and filtered using a non-local mean filter and also normalized to reduce noise.
