A large-scale infrastructure model for CO2 disposal and EOR—economic and capacity potential in the North Sea

Publisher Summary This chapter illustrates an injection scenario that includes most of the Norwegian oil reservoirs in the North Sea oil reservoir. In order to elucidate the possibility of combining CO 2 storage with EOR, a techno-economic model for a large scale scheme for CO 2 deposition in Norway's North Sea oil provinces has been developed. A CO 2 -transportation module calculates the transportation costs for CO 2 from export terminals to the oil provinces. An EOR module predicts the increased oil recovery due to CO 2 injection in water-flooded reservoirs. In order to convert from a water-injection scheme to CO 2 injection large modifications of the oil production installations are needed. A possible solution for this has been sketched, and the costs for the necessary modifications and new installations for CO 2 injection have been estimated and are also included into the techno-economic model.
