Abstract

Climate change is one of the major global concerns. Emission of anthropogenic greenhouse gases is the main cause of climate change. One way of reducing the emissions is the application of carbon capture and storage (CCS) in geological formations. In this study, feasibility of CCS was studied in an Iranian gas production area located in the northern Persian Gulf coast in the south of country. There is a close and direct relationship between the number of oil and gas reservoirs and amount of CO2 emissions in Zagros area in Iran.Therefore, finding an appropriate geological structure, i.e. site selection, in Zagros region is the first priority for the injection. The recognized aquifer at a depth of 1500 meters below the sea level in Fars area in Zagros, which is covered by Nar cap rock, showed a good prospect for CO2 injection. This aquifer is located in Lower-Dalan with an appropriate reservoir property that was investigated in this paper. Simulation studies indicated that one ordinary reservoir in this area is capable of capturing at least 41.41E9 Sm3 (68 million ton CO2) over 10 years of injection
