英文名称：Carbon dioxide capture, transportation and geological storage — Carbon dioxide storage using enhanced oil recovery (CO2-EOR)

发布日期：2019-01

标准范围

This document applies to carbon dioxide (CO₂ ) that is injected in enhanced recovery operations for 
oil and other hydrocarbons (CO₂ -EOR) for which quantification of CO₂ that is safely stored long-term 
in association with the CO₂ -EOR project is sought. Recognizing that some CO₂  -EOR projects use non-
anthropogenic CO₂ in combination with anthropogenic CO₂ , the document also shows how allocation 
ratios could be utilized for optional calculations of the anthropogenic portion of the associated stored 
CO₂  (see Annex B).
1.2 Non-applicability
This document does not apply to quantification of CO₂ injected into reservoirs where no hydrocarbon 
production is anticipated or occurring. Storage of CO₂ in geologic formations that do not contain 
hydrocarbons is covered by ISO 27914 even if located above or below hydrocarbon producing reservoirs. 
If storage of CO₂ is conducted in a reservoir from which hydrocarbons were previously produced but 
will no longer be produced in paying or commercial quantities, or where the intent of CO₂ injection 
is not to enhance hydrocarbon recovery, such storage would also be subject to the requirements of 
ISO 27914.
1.3 Standard boundary
1.3.1 Inclusions
The conceptual boundary of this document for CO₂ stored in association with CO₂ -EOR includes:
a) safe, long-term containment ofCO₂ within the EOR complex;
b) CO2 leakage from the EOR complex through leakage pathways; and
c) on-site CO₂ -EOR project loss of CO₂ from wells, equipment or other facilities.
1.3.2 Exclusions
This document does not include the following:
a) lifecycle emissions, including but not limited to CO₂ emissions from capture or transportation of 
CO₂  , on-site emissions from combustion or power generation, and CO₂ emissions resulting from the 
combustion of produced hydrocarbons;
b) storage of CO₂ above ground;
c) buffer and seasonal storage of CO₂ below ground (similar to natural gas storage);
d) any technique or product that does not involve injection of CO₂ into the subsurface; and
e) emissions of any GHGs other than CO₂ .
NOTE Some authorities might require other GHG components of the CO₂ stream to be quantified.
