Enhanced oil recovery EOR

Production using EOR technology is projected to contribute an additional 6.4 mb/d 3 to world oil supply in 2030, with most of the increase occurring after 2015 (Figure 11.10). Three-quarters of this increase comes from just four countries: the United States, Saudi Arabia, Kuwait and China (in ranked order). Cumulative production in 2007-2030 amounts to 24 billion barrels, out of an estimated potential of about 300 billion barrels - of which one-third is in Saudi Arabia (see Chapter 9).

Most of the new EOR projects that are expected to be implemented during the projection period involve CO2 injection. In total, about 9.8 gigatonnes of CO2 is captured and stored in CO2-EOR oil projects over the projection period.4 These projects are exclusively onshore, as the technology for offshore CO2-EOR is not expected to be sufficiently advanced for it to be deployed before the end of the projection period. Current EOR technology typically recovers about an additional 10% of oil in place. A bigger and more widely applied carbon penalty than assumed in the Reference Scenario (see Chapter 1) would significantly increase the potential for EOR.

3. Over and above the estimated 2.5 mb/d of EOR production from existing fields - see Chapter 9 (Table 9.2).

4. This projection assumes that about 2.5 barrels of oil are recovered per tonne of CO2 injected. §
