As part of the Canyon Express project, four intelligent completions were installed in the Total Aconcagua Field and two in the Marathon Oil Camden Hills Field, Mississippi Canyon Blocks 305 and 348 respectively, in ultra-deepwater Gulf of Mexico. As a result of production optimization objectives and reservoir conditions, the intelligent completions have been utilized extensively to enhance field performance since installation and host platform commissioning in 2002.
With the use of direct hydraulic open/close valves, various zones have been shut-in and cycled open to optimize production. The objectives of this paper are to provide an overview of using intelligent completions to improve well performance, to discuss the reliability of the intelligent completion equipment three years after installation, and to qualitatively present the value proposition of reservoir management of intelligent completions.
Faced with reservoir depletion, suspected sand production, and water influx, the intelligent completions have proven themselves useful in the management of these assets.
