Title History matching of the Fensfjord reservoir and optimization of the Integrated Production Model for the Brage field, Norway. Author Serafini, W.E. Contributor Jansen, J.D. (mentor) Rossen, W. (mentor) Faculty Civil Engineering and Geosciences Department Petroleum Engineering Date 2009-07-16 Abstract With the advent of smart fields new tools for monitoring and field management were needed. Integrated asset modelling allows improving the understanding of the field’s performance and production network, fluid flow behaviour and optimization at any stage and level during the life of the field. This approach enables the optimization of production by adjusting control parameters taking into account surface facilities constraints and the interactions between surface and subsurface systems. Using material balance modelling as a tool for history matching, the Fensfjord reservoir showed that the North and West tanks are behaving as separate compartments. There is some communication between the South and Central tanks and that the aquifer is giving some support to the North and South but not to the Central tank. In this work, given the design of the integrated model and the hierarchical structure of the software it is best to define the objective function, control variables and constraints within each application which has its own optimizer. The impact of scenarios with respect to the total system can be modelled. This brings valuable information on whether in fact the new scenario can be handled by the current surface facilities or if an upgrade is needed and how cost effective it will be. Furthermore, the premise that optimal gas lift rate allocation can bring significant changes in production when gas processing is constrained by surface facilities was verified, yielding an increase in 4.2 % of cumulative production over a period of 3 years.
