Predicting top seal capacity is difficult—even in idealized experiments in which all variables are known to a degree unobtainable in practical prospect assessment. The predicted height of hydrocarbon columns calculated from pore throat diameters in uniform glass bead packs is 160–500T larger than heights actually observed in experiments.<ref name=ch10r12>CatalanXiaown, L., F., Chatzis, I., Dullien, F., A., L., 1992, An experimental study of secondary oil [[migration]]: AAPG Bulletin, vol. 76, no. 5, p. 638–650.</ref> If we cannot predict the height of hydrocarbon columns trapped in a controlled experiment with uniform glass beads and known variables, then we must be cautious in prospect analysis.
