1.1 Applicability
This document applies to carbon dioxide (CO 2 ) that is injected in enhanced recovery operations for oil and other hydrocarbons (CO 2 -EOR) for which quantification of CO 2 that is safely stored long-term in association with the CO 2 -EOR project is sought. Recognizing that some CO 2 -EOR projects use non-anthropogenic CO 2 in combination with anthropogenic CO 2 , the document also shows how allocation ratios could be utilized for optional calculations of the anthropogenic portion of the associated stored CO 2 (see Annex B).
