통합생산모델 구축을 통한 해상유전 생산최적화 적용 가능성 연구

Abstract

Oil industry has been extremely matured during last decades. It becomes very hard to discover new giant fields even with deep sea drilling and exploration works. Therefore, it is essential to manage discovered field efficiently.

With making integrated decision-making system of field management, well and reservoir surveillance data are utilized to explain performances of sub-surface and surface facility systems. Especially, Integrated Production Modeling(IPM) is commonly used to describe pressure interaction between reservoir and surface facilities, and its efficiency has been proved through several field cases.

In this study, IPM is suggested for Captain filed, located in the United Kingdom sector of North Sea, with various operating conditions of injection water, power water, produced water handling volumes, FPSO's off loading capacity, etc. It comprises with coupling of 5 material balance models, 25 production well models, 10 water injection well models, and one surface facility model. By comparison with the measured data, the model forecasts show reliable results with 7% and 5% discrepancy in production well and injection well performances, respectively.
