Abstract
MRI is applied to the visualisation of wetting heterogeneities evidenced by water proton T1 contrast at 0.1 T. Water saturated Fontainebleau sandstone samples were examined either in their original water-wet condition, or after silanation. T1, T2Hahn, and T2CPMG were measured for several porosities. T1 and T2CPMG of hydrophobic samples are both twice longer than those of hydrophilic ones. This good contrast allows us to observe wetting heterogeneities in T1-profiles and T1-weighted images.Entities:
