Results analysis

Comparison of the two fluent simulations: effects of the viscosity.

The oil recovery is larger when the viscosity increases, because it creates big bubbles which are flowed out by water.

In oil industry, the chemical products are used to decrease viscosity in the case of porous medium reservoirs, which decreases the capillarity pressure and therefore helps oil to go up.

It is estimated in the case of the caves network reservoir, increase the viscosity with chemical products can be considered as a method of oil enhanced recovery ratio.
