Gas lift in Terra Nova production wells serves two purposes. The first is to increase the rate at which reservoir fluids can be produced, especially as water cuts increase with time and reservoir pressure diminishes. The second is to stabilize flow in the wells, flowlines and flexible risers. This paper describes the application of engineering tools to achieve an optimized subsea gas lift design for a 6350 m3/d (40,000 bpd) production rate, taking into account reservoir, wellbore, subsea and topsides constraints.
