Two-phase flows in micromodels
Two-phase experiment in a micromodel that represents complex natural porous media (sandstone)
A non-wetting fluid (oil) displaces a wetting fluid (water/glycerin).
Black: grains
Green: water/glycerin + particles
White: oil
Size: 100µmx150µm (x12µm depth)

The approaching interface result in the perturbation of the flow pattern.

After the passage of the interface (oil in white), preferential paths continue to change
