A terrestrial oil field in Mexico is chosen as the site. A schematic diagram of EOR is as shown in Figure 1. About half of the injected CO2 is expected to remain underground. Figure 1 Schematic diagram of EOR Major EOR projects around the world are as follows: 1 Table 1 Major EOR projects around the world Name Type of Year Depth CO2 injection Cumulative CO2 reservoir per year (Mt- injection (Mt- CO2) CO2) In Salah depleted gas 2004 1850- 1950 1.2 2.5 （Algeria ） field (at 2008) Weyburn oil/gas fields 2000 1450 3.65 12 （Canada） (CO2-EOR)
