| Summary: | 碩士 === 國立成功大學 === 資源工程學系碩博士班 === 93 === Oil leakage occurred near the national highway in Southern Taiwan and was discovered in March 1998. Since the discovery, free product recovery started and continued until June 2000. Field data showed that the oil recovery rate correlated with precipitation. Every year, the oil recovery rate during rainy season was higher than that of the previous dry season. The effect of precipitation on the cumulative oil recovery was manifested by a multiple-S-shaped curve observed at the site, which could be calculated and interpreted by the immiscible displacement theory. Both the field data and the model prediction showed that the oil recovery of a waterflood was extremely effective in the early stage and dropped sharply after water breakthrough.
