Got it the moment just when I needed it

this was great

Hello Professor, thanks for your video! If it's water-wetting, will the stage of forced water injection happen? For example, raising the water pressure causes some trapped non-wetting phases in the pore body to overcome the capillary resistance of the throat connected to it, then the S1 or Sw further increases.

Dear proffessore , is it true that : at conditions above the capillary pressure at Swi, capillary forces are entirely dominant, whereas outside the capillary pressure at 100% wetting-phase saturation, the conditions are analogous to the complete dominance of gravity forces, and within these two Pc-Sw endpoints, both gravity and capillary forces can be considered as being active.

This is not really correct - there is simply an equilibrium between gravitational and capillary forces. At the pore scale capillary forces dominate for the whole saturation range.
