Note the direction of saturation change and base permeability in the subtitle. Label the relative permeability endpoints. Annotate your curves with arrows to indicate the direction of saturation change. Determine the irreducible water saturation. b. C. Determine the critical oil saturation. d. Determine the maximum potential oil recovery by waterflood as a fraction of pore volume.
