Abstract This paper presents a general and systematic approach to address decisions in the design and operation of offshore oilfields. The approach is based on the formulation of mathematical models that are formulated to accommodate multiple production profiles. The profiles can be used to assess either the best strategy or, instead, possible implications in changing policies during the operation. The work decomposes the problem in two stages: the determination of the optimum drilling centre and the determination of the optimum drilling schedule to meet a specified production profile. The proposed method simultaneously addresses and optimizes the operation of the main production facility and an arbitrary number of satellite fields. Fields and wells are selected to give the overall lowest CAPEX for the development. The method is an improvement over previous work and provides a full optimisation of life-cycle drilling costs. © 2007 Elsevier B.V. All rights reserved.
