Abstract [en]

The enhanced oil recovery (EOR) methods such as polymer flooding to increase oil production from water flooded fields are becoming more attractive. Water flooding can increase recovery up to 20-40%. Various EOR methods can yield significant increase in the oil recovery when compared to conventional water flood projects in certain reservoirs. The main objective of this study is to analyze efficiency of polymer flooding for enhanced oil recovery for Norne field E-segment using the Eclipse 100 simulation model of the reservoir. The simulated model was manually history matched by modifying transmissibility factors, fault transmissibilities, the skin factor and Kh values of the production wells. As a result of all adjustments the best possible history match was obtained. The polymer flooding was analyzed and tested on three dimensional, homogenous and flat synthetic model. The oil recovery increase about 8%. The injection well F-3H was evaluated as the most appropriate well for the polymer flooding scenario. The polymer solution concentration sensitivity and injection rate sensitivity were performed to assess the efficiency of polymer flooding in the Norne E-Segment. The oil recovery increased up to 1%, therefore it can be concluded that polymer flooding is not a good scenario for the Norne field E-Segment.
