Abstract
Every year, huge amounts of oil are left behind due to early water invasion to wells in water-drive reservoirs. Thus, efficient management of oil reserves requires an understanding of the mechanisms that control the bypassing of oil with water. This paper presents the results of a simulation study aimed at understanding the relationship between water cut development and oil bypassing. Water cut vs. time plots obtained for different reservoir conditions have been analyzed as potential diagnostic tools for the oil recovery process. The results show that there is good correlation of the rate of water cut development in time with oil bypassing. The water cut rate is also a good indicator of the oil displacement front stability and the severity of water underruning. In general, slow water cut development is associated with unstable displacement, thin and long water tongues and substantial oil bypassing.
