... to the injection of the vapor phase may significantly alter the fluid flow performance and behavior, as represented by the relative permeability to fluids in the formations. Therefore, in TEOR, the relative permeabilities can change with a change in temperature. Also, there is no model that accounts for the change...

Al-Shalabi; Abdul Ravoof Shaik Summary A meticulous interpretation of steady-state or unsteady-state relative permeability ( K r ) experimental data is required to determine a complete set of K r curves. In this work, different machine...

...M. Yousefi; H. Dehghanpour Summary The two-phase flow of immiscible fluids in porous media has been studied for a long time in different disciplines of engineering. Relative permeability ( k r ) is one of the constitutional relationships in the general equation governing immiscible displacement...

...Pål Ø. Andersen Summary Steady-state relative permeability experiments are performed by coinjection of two fluids through core plug samples. The relative permeabilities can be calculated using Darcy’s law from the stabilized pressure drop and saturation of the core if capillary end effects...

...Eric Sonny Mathew; Moussa Tembely; Waleed AlAmeri; Emad W. Al-Shalabi; Abdul Ravoof Shaik Summary Two of the most critical properties for multiphase flow in a reservoir are relative permeability ( K r ) and capillary pressure ( P c ). To determine these parameters, careful interpretation...

... model, respectively. Table 2 summarizes the different lithofacies and corresponding petrophysical properties used in the geologic model. Permeability used here is the horizontal permeability ( k h ), and an anisotropy ratio ( k v /k h ) of 0.1 was used for the model. The relative permeability...
