Scope

This document applies to CO2 injected in oil and other hydrocarbon enhanced recovery operations. In CO2-EOR projects, it is necessary to quantify the long-term safe storage of CO2. Considering that some CO2-EOR projects combine non-anthropogenic CO2 emissions with anthropogenic CO2 emissions, this document also provides a method of using an allocation ratio to selectively calculate the proportion of anthropogenic CO2 associated with storage (see Appendix B).
