Interpretation of experimental data (crosses) from Henderson et al. (1998) where average condensate saturation (a) and inverse effective relative permeabilities in (b) and in (c) are plotted against . Straight lines are drawn through the high rate data for each flow fraction F to find the intercept (marked with circle points) corresponding to saturations and relative permeability points corrected for end effects. The slopes of the lines provide values of C_s·C_o, C_w at each fraction.
