In view of the characteristics of thin reservoirs, bottom-water breakthrough, and current situation of rapid increase of water-cut in the producing wells of North Buzachi Oilfield in Kazakhstan, the existing wells were used for sidetracking in horizontal drilling to keep away from the reservoir bottom-water coning effectively, maximizing the interval of low water-cut oil recovery of the wells. The research provides a cost-effective method for solving similar problems of wells with high water-cut in such reservoirs.
