Relationship between IFT and the other two indicators: microdispersion and water-soluble organics. (a) The IFT in 0.164 M NaCl brine plotted versus the normalized FID signal for the organics content in 0.164 M NaCl brine after oil equilibration for all oils. (b) The IFT in 0.164 M NaCl brine plotted versus the microdispersion ratio in 0.164 M NaCl brine for all oils. The IFT is measured using the brine pre-equilibrated with rock and oil (1:1 vol/vol). Each point represents one specific oil.
