Enhanced Oil Recovery Using C02 Flooding: Nome Field E-Segment Case Study

Background: The Nome field is located 80 km north of the Heidrun field in the Norwegian Sea discovered in December 1991. Aim: The feasibility of using C02 flooding as a method of enhanced oil recovery in a segment of the Nome 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 Nome field E-Segment was used to test the effect of C02 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 C02 injection was 32%. Conclusion: This study indicates that there is a feasibility of carrying out C02-E0R in the Nome field based on initial CQ2-EOR screening and simulation.
