The use of integrated system modelling of wells and facilities and the application of performance improving chemicals and novel techniques allowed Shell Gabon to increase Rabi field output by nearly a factor of two over the initial projections. Optimisations are carried out in a consistent and systematic manner without jeopardising system integrity and safety standards. These efforts increased project profitability while obviating the need for major system extensions. Some (identified) upgrading measures are still required to reduce long-term operating costs and to reduce deferments.
