This paper presents information regarding the installation of Intelligent Well Completions in Lula and Sapinhoá fields, at the Santos Basin Pre-salt Cluster. The technology is intended to improve reservoir management capability by using remote operated flow control valves and real time pressure and temperature monitoring for each perforated interval, which corresponds to different reservoir zones. The benefits are obtained at the expense of additional challenges for well engineering, since well completion design becomes more complex and overall associated risks increase. Detailed and integrated planning is essential for the success of the operations, starting at the earliest phases of the well design and continued through detailed execution plans. The project team considered integration between downhole, subsea and topside systems as one of the main concerns during different planning phases. First intelligent completion installations have been successful in pre-salt area, with no compromise to projects timeline or to the system performance. Applying the best practices learned during initial installations has been a key factor to achieve even better results in the following wells. Approximately 25 wells have been equipped with intelligent completions in Santos basin pre-salt area. Significant increase in performance and implementation time has been observed as a considerable amount of improvements have been made on system design and installations procedures.
