Silva, L.M.R. and Guedes Soares, C. (2021), “Oilfield development system optimization under reservoir production uncertainty”, Ocean Engineering, Vol. 225, 108758 (14 pages)

An optimization approach is proposed to support the design decisions of floating production systems and their subsea layout, regarding the production and investment planning. The optimization methodology extends a previous approach by including the dynamics and uncertainty of the oil production during the reservoir lifetime, and the associated dynamics of the gas and water production. The new model integrates production forecast with facilities requirements and economic optimization. An uncertainty assessment methodology is provided and applied to the reservoir production including its decline curve. A case study from Brazil waters is presented and discussed to demonstrate the performance of the method applied to a specific production system.
