Zusammenfassung:Considering the worldwide development of tight and ultra-tight oil reservoirs, the increasing demand for fossil energy and long-term environmental concerns regarding large CO2 emissions, application of dual-purpose carbon dioxide (CO2) sequestration/enhanced oil recovery in oil reservoirs has gained considerable attention [1,2]. However, unlike its mature application in conventional reservoirs, the effectiveness of CO2 EOR and geological sequestration in tight reservoirs is still under investigation [3]. In this work, we investigated the efficiency of different injection strategies on simultaneous CO2 EOR and storage in ultra-low permeability (
