Simulations with capillary pressure with pumping

We compare the influence the case with capillary and the case without capillary pressure.

Saturation without $P_c$, time=100000 s

Saturation with $P_c$,  time=100000 s


We observe that the capillary pressure allows the oil to go up and help to the pumping .
Moreover we know that pumping create a lack of oil which increases the influence of the capillary pressure.
