Local oil saturation (fluid composition within the void spaces of sandstone) is computed from pixel image data. Limitations of CT observation of fluid displacement are discussed. Images of viscous fingering, time derivatives of local composition, and residual oil distribution are given for the case of water displacing oil from porous media.
