Aim: The feasibility of using CO2 flooding as a method of enhanced oil recovery in a segment of the Norne field was analysed. Methods: A numerical simulation using a black oil simulator approach was taken. For this study, a synthetic reservoir model, with fluid and rock properties from Norne field E-Segment was used to test the effect of CO2 flooding on recovery factor. Results: The key findings are as follows: (1) The oil recovery of the base case after 7 years of water flooding was 40% (2) The recovery factor obtained after 15 years of continuous CO2 injection was 32%. Conclusion: This study indicates that there is a feasibility of carrying out CO2-EOR in the Norne field based on initial CO2-EOR screening and simulation.enSimulation; CO2 flooding; Enhanced Oil Recovery (EOR); recovery factor.Article
