Imbibition process takes places by displacement of non-wetting phase by wetting phase.
In the drainage process, the non-wetting phase displaces wetting phase from the large pores.
Capillary pressure can be defined as the subtraction of non-wetting phase pressure and wetting phase pressure; its direction is from wetting phase to non-wetting phase.
In co-current imbibition, wetting phase pushes non-wetting phase out of the matrix in the same direction.
Since non-wetting phase relative permeability (k ro), wetting phase relative permeability (k rw) and capillary pressure (P c) are discontinuous functions of water saturation (S w), PDE formula (9) can not be solved directly.
Both Samples A and B show a less energy consuming movement for wetting phase, and energy consuming for non-wetting phase.
Imbibition can be defined as the inflow of wetting phase and the displacement of non-wetting phase in the porous media under the forces of capillary pressure, gravity and buoyancy force.
S we ∗ could be expressed as follows for the drainage case S we ∗ = S we - S wer 1 - S wer (8 where S we * is normalized wetting phase saturation; Swer is residual saturation of wetting phase.
