Abstract
Rational conceptual design is a formidable task to ensure feasible and economic operation along offshore oil field development lifecycle. An integrated production modeling (IPM) approach has to be adopted at the conceptual design stage since it enables the assessment of the spatio-temporal interaction between the subsea pipeline network and the reservoir. This work reports the development of an computer-aided IPM tool to facilitate effective subsea scenario comparison and selection considering the lifecycle performance of both the production system and the injection system. Three performance indicators are used for scenario comparison and selection, namely, NPV, recovery rate, and wax-free index. A case study demonstrates the application of the IPM tool in assessing the effect of subsea water separation, for both green field design and brown field revitalization purposes. The developed IPM tool allows the production engineer to focus on the subsea configuration itself since production performance of each candidate scenario is effectively evaluated from autonomous simulation results under the same development logic.
