Effects of displacement pressure, pressure gradient, and flow rate on the shape of relative permeability curves have long been a controversial subject in petroleum literature. For drainage experiments it has been reported that the relative permeabilities are independent of flow rate. However for imbibition experiments the rare literature, mainly concerned with oil-water phases, does not agree on this point.
