In this paper, a simplified 2D control relevant model for a slightly slanting wedge-shaped black oil reservoir is made more realistic by incorporating model uncertainty. The uncertainty in the model is computed via Monte Carlo simulation. Furthermore, based on this model with uncertainty, a Proportional + Integral (PI) controller is implemented to increase oil production while minimizing water production. A PI controller is used to control the valve opening of the Inlet Control Valves (ICVs) in the production well. Implementation of a PI controller enhanced the oil recovery in 1000days by 1.79%, while the total water production is reduced by 2.59%.
