AbstractThe injection of carbon dioxide in oil and gas reservoirs (Enhanced Hydrocarbon Recovery, EHR) or in aquifers is a promising way to cope with the short-medium term issue of greenhouse gas emission mitigation. Although CO 2 -EHR projects represent the best economical opportunities, the CO 2 injection projects in deep aquifers offer the largest capacity potential for long-term CO 2 storage. The design of a CO 2 injection project mainly depends on the results of reservoir models.Using this approach, we show that an unique set of parameters enables modeling of CO 2 injection for various thermodynamic conditions and fluid systems. Therefore, such approach leads to predictive simulations at the core scale, which contributes to the accuracy of the performance prediction of the CO 2 injection at the reservoir scale, if the main geological features (heterogeneities) are included into the large scale model.
