Pore-Scale Imaging of the Oil Cluster Dynamic during Drainage and Imbibition Using In Situ X-Ray Microtomography

Figure 8

Two-dimensional cross-sectional views (diameter = 1600 voxels) of the pore-scale fluid occupancy in both water-wet (slice = 834, 25.75 mm from the inlet) and oil-wet plugs (slice = 158, 24.33 mm from the inlet). (a) Exp. number 3 in water-wet plug. (b) Exp. number 4 in water-wet plug. (c) Exp. number 3 in water-wet plug. (d) Exp. number 8 in oil-wet plug. (e) Exp. number 9 in oil-wet plug. (f) Exp. number 10 in oil-wet plug.
