This paper describes the considerations and integrated design process for specifying the Cv characteristics of an adjustable flow control valve for an intelligent well. The paper emphasizes the need to consider the complete well as a control system, including inflow, choke performance and well bore outflow performance. The paper describes a method for establishing the most suitable flow control design for the application. The method combines nodal analysis and choke performance modelling to model the behaviour of the entire well bore system. This analysis is extended to multiple layer or multiple zone intelligent well completions. An example of the analysis is presented.
