... and fractional flow. Bimodal pore systems (abundant in the Middle East) can have such low relative permeability to water at high saturations that even 70% water saturation can produce dry oil. In such cases, talk of a transition zone is counterproductive as it implies high water production. "Thomeer hyperbolas...

The modelling at reservoir scale needs to honour known measurements, for example the water saturation...
