The thermodynamic equilibrium of the reservoir fluids may end up with the pressure difference between fluid phases (called capillary pressure) due to difference in fluids interaction with rocks:

In most popular practical case of a 3-phase fluid model this will be:
| oil phase pressure | ||||
| gas phase pressure | ||||
| water phase pressure | ||||
| average phase pressure |
