ABSTRACT
Niger desert oilfield reservoir is characterized by strong non-homogeneity and large differences in permeability. It has caused the problems of uneven fluid production, rapid rise of water cuts in oil wells, and reduced recovery of oil reservoirs. Eight wells were successfully applied in the Niger oilfield, and good water control and oil production were achieved. This paper forms a set of inflow-control and oil recovery techniques applicable to desert oilfields by studying the operation process and application effects, which provides a reference for other oilfields to manage high water cut oil wells.
