... production. Spontaneous imbibition to expel oil from the low permeable matrix is a time-dependent process and both injection rate and oil viscosity are important factors affecting the contribution of capillary and viscous forces to the oil production. It is hypothesized that when capillary forces...

The oil recovery profiles displayed a piston-like displacement indicating that oil recovery was controlled by capillary forces at the injection rate used. SENDRA was used to simulate the effect of wettability on relative permeability and capillary pressure curves...
