Abstract: The adverse effect of produced water on oil inflow rate and downhole production system cannot be over emphasis. The challenge posed by it is felt both at the upstream and downstream. This is due to the reversed in the function of the reservoir pressure in driving the produced fluids to the surface. Wiggin’s model for multiphase was reviewed and used to analyse the inflow performance relationship curves results obtained from the simulation of production data of oil well 1 and 2. The IPR generated in the presence of water in the inflow stream was further investigated by remodeling wiggin’s model on Execl program (figure 1). From the simulation, the absolute open flows (AOF) for well 1 were 5576.2 bbl/d and 3771.4 bbl/d for multiphase and single phase respectively (Figure 2). Similarly, well 2 have 9736.1 bbl/d and 7612.4 bbl/d (AOF’s) for multiphase and single phase flow respectively (figure 3). The investigation method show more oil production based on the improved IPR curves (figures 6 and 7) obtained as a result of modeling the bottomhole flowing pressure in inverse assumption in the presence of water in the inflow stream using.
