Abstract: This study presents an integrated simulation of reservoir and manifold-based production system for oil production and the influence of such equipment in oilfield management. The production strategy analysis methodology was evaluated in five sequential separated stages: 1) allocation of all wells (producers and injectors); 2) number of wells (suitable for field production); 3) use of manifolds (number of manifolds, allocation and groups of wells connected to them); 4) sensitivity analysis involving the variation of the entire gathering system diameters; 5) platform allocation. Each stage considered the best result of the previous stage. The results identified the importance of each stage in the production strategy and presented an ideal configuration with adequate financial return to produce this field. Besides that, the analysis identified the most important stages for more complex optimisation with less discontinuities, convergence problems and computational effort. The methodology contributed to an evaluation and improvement in the production strategy. [Received: July 29, 2020; Accepted: October 6, 2020]
