  1. RELATIVNE PROPUSNOSTI

  2. k = apsolutna (specifična) propusnost Za uvjete u ležištu (Sw>0, So>0 i/ili Sg>0) potrebna je prilagodba (modifikacija)Darcyevog zakona: Ukoliko se fluidi ne miješaju, gledajući neovisno protok pojedinog fluida, dotični protok možemo izraziti pomoću efektivnog koeficijenta propusnosti: ko, kw, kg

  3. Efektivna propusnost ovisi o: zasićenju geometriji pora stijene kontaktnom kutu – močivosti sa stijenom kr=kef/k

  4. Zasićenje se mijenja tokom proizvodnje:
