... because oil flow is greater lower down and the relative permeability (and saturation) must be higher to accommodate the flow, since the driving potential gradient is limited to that creat d by gravity. The situation is different in SAGP in the gas region because of the temperature gradient caused...

Hence, their accurate determination is essential for proper economic and reservoir...

... reservoir pressures have already been drawn down to free-gas conditions and a new frac produces under three-phase flow instead of two phases, essentially cutting oil production by a factor of 4 times due to relative permeability effects. Gas rates even as low as 5 e3m3/d affect oil production of less than 5...

... Abstract Accurate relative permeability data are essential for predicting the performance of two-phase flow through porous media. Many factors, such as the rock and fluid properties, may affect the measurement of relative permeability. However, the saturation levels of the fluids flowing...
