ISO 27916:2019 pdf download.Carbon dioxide capture, transportation and geological storage — Carbon dioxide storage using enhanced oil recovery (CO 2 -EOR)
1 Scope
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).
1.2 Non-applicability
This document does not apply to quantification of CO 2 injected into reservoirs where no hydrocarbon production is anticipated or occurring. Storage of CO 2 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 CO 2 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 CO 2 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 CO 2 stored in association with CO 2 -EOR includes:
a) safe, long-term containment of CO 2 within the EOR complex;
b) CO 2 leakage from the EOR complex through leakage pathways; and
c) on-site CO 2 -EOR project loss of CO 2 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 CO 2 emissions from capture or transportation of CO 2 , on-site emissions from combustion or power generation, and CO 2 emissions resulting from the combustion of produced hydrocarbons;
b) storage of CO 2 above ground;
c) buffer and seasonal storage of CO 2 below ground (similar to natural gas storage);
d) any technique or product that does not involve injection of CO 2 into the subsurface; and
e) emissions of any GHGs other than CO 2 .
NOTE Some authorities might require other GHG components of the CO 2 stream to be quantified.
3.1 anthropogenic
carbon dioxide carbon dioxide that is initially produced as a by-product of a combustion, chemical, or separation process (including separation of hydrocarbon-bearing fluids or gases) where it would otherwise be emitted to the atmosphere (excluding the recycling of non-anthropogenic CO 2 ) Note 1 to entry: The chemical symbol “CO 2 ” is synonymous with “carbon dioxide”. Accordingly, the two ways of writing out “carbon dioxide” and “CO 2 ” are used interchangeably in this document. Note 2 to entry: If CO 2 that meets the definition of anthropogenic CO 2 is not included in a supplemental quantification of associated storage of anthropogenic CO 2 (e.g., because it was received and injected by a CO 2 – EOR project prior to the quantification period) it will generally be treated as non-anthropogenic CO 2 in that quantification.
