| Abstract: |
| A numerical model of reservoir production with the functionalities of real-time monitoring and control was established based on traditional reservoir numerical model and a set of proactive and reactive feedback control algorithms were proposed. Three intelligent well production strategies (i.e., reactive control, proactive control and the combined control) were investigated in a scenario of water-flooding driven horizontal production wells. The results show that compared with the conventional well production, the feedback controled production strategies can increase oil production, decrease water production, and thus improve the net present value. The proactive control displays advantages in the early production stage while the reactive control outperforms in the late stage, and the production strategy with combined reactive and proactive controls has the most advantage in economic return aspect. |
