Optimal Planning for Deepwater Oilfield Development Under Uncertainties of Crude Oil Price and Reservoir

Abstract

The development planning of deepwater oilield directly inluences production costs and beneits. However, the uncertainties of crude oil price and reservoir and the special production requirements make it diicult to optimize development planning of deepwater oilield. Although there have been a number of scholars researching on this issue, previous models just focused on several special working conditions and few have considered energy supply of loating production storage and oloading (FPSO). In light of the normal deepwater production development cycles, in this paper, a multiscenario mixed integer linear programming (MS-MILP) method is proposed based on reservoir numerical simulation, considering the uncertainties of reservoir and crude oil price and the constraint of energy consumption of FPSO, to obtain the globally optimal development planning of deepwater oilield. Finally, a real example is taken as the study objective. Compared with previous researches, the method proposed in this paper is testiied to be practical and reliable.
