Dual control of flow field heterogeneity and immobile porosity on non-Fickian transport in Berea sandstone

Both flow field heterogeneity and mass transfer between mobile and immobile domains have been studied separately for explaining observed anomalous transport. Here we investigate non‐Fickian transport using high‐resolution 3‐D X‐ray microtomographic images of Berea sandstone containing microporous ce...
