An oil-water SS displacement experiment was carried out on a 5.0 cm long and 3.0 cm diameter sandstone core plug taken from Duyung-1 well in Terengganu. The porosity of the plug is 25% and the grain density is 2.65 g/cm3. Oil and water densities are 0.85 g/cm3 and 1.05 g/cm3, while viscosities are 2.0 cP and 1.0 cP, respectively. The differential pressure for the test is 12.94 psi. Other data are provided in the following table. Calculate and plot the oil-water relative permeability data and explain the graph
