During preliminary research for dynamic study, a leakage oil which was assumed to be Korean crude oil was analyzed to determine whether the oil is crude or waste, in which gas chromatographic and ASTM analyses, mixing tests, comparison with foreign crude oils, prediction of hydrogen content, and impurities tests were conducted. And a bridge from gas chromatogram of oil to ASTM curve was built for any size oil sample treatments. The batch tests demonstrated that the oil characteristics would change by selective adsorption and by selective solubility during the oil migration through the underground structures, and suggested the study in dynamic leakage oil characteristics for valid oil evaluations. Silica gel was used instead of clay or sand for adsorption experiments. The oil passing out through the silica gel and water, the UOP K factor varies as functions of the oil and water flow rate, the quantity of silica gel the oil passes through, and the history of the leaked oil under isothermal and isobaric conditions. And, it was found from adsorption experiment of oil on silica gel that a component in $C_{11}$ boiling range is most selectively adsorbed and was taken as a key component. The key component concentration varies also with the same parameter as the case of UOP K factor. The empirical equations were obtained for these two key variables, K and the key component, and could be used for evaluating the original location of the leakage oil source and the original characteristics of the leakage oil. In these studies the other two empirical equations were obtained i.e., the volume average boiling point and the UOP K factor can be predicted from volume average carbon number which can easily be calculated from the gas chromatogram of oil, by use of the two equations.
