Abstract
Summary Intelligent-well completion (IWC) is an emerging technology that allows operators to optimize reservoir management and field facilities performance. The implementation of this technology has generally been restricted to new field development because of the perceived complexity of integrating high-end IWCs (e.g., combined monitoring and flow control) into current subsea-production-system (SPS) designs. However, intelligent completions can be applied to mature fields in which reservoir performance and value added by IWC are well understood. The BP Machar well application is a typical example. One of the challenges facing the project team at the BP Machar well was the integration of the IWC-control system within the constraints of the existing SPS. Minimum modification to the existing hardware and control-system equipment was required. A system approach-in line with the forthcoming ISO 13628, Part 6 [intelligent-well interface standardization (IWIS) addendum] standard for integration of IWCs into SPSs-was used to ensure robustness of the design and testing concepts.
