Web6 mrt. 2024 · In such mixed-wet situations, we observe that the movement is slower (minutes instead of seconds), is more frequent, and involves larger fluid volumes. This indicates a different flow regime that cannot be estimated from an extrapolation from strongly wetting rock. WebIn mixed wetting, small pores occupied by water are water-wet, while larger pores contain oil and are oil-wet. In fractional wetting , variations in minerals, which have differing surface chemical properties, cause portions of rock to be water-wet and other portions to be oil-wet.
