Controllability and observability in non-linear flow reservoir model - RETRACTED

[This paper has been withdrawn by the publisher]. In this study, the authors analyse and interpret the controllability and observability properties of a non-linear two-phase flow reservoir model, with particular focus on the saturation dynamics. They investigate the extent to which such models are controllable and observable; and how these properties are affected by well locations, geological heterogeneities and fluid properties. It is shown that well configuration and fluid front dynamics are significant factors that affect the extent to which a non-linear two-phase flow reservoir model is controllable and observable. Overall, these findings are very promising and further demonstrate the applicability of systems theoretic in this subject area.
