Full title and description

Carbon dioxide capture, transportation and geological storage — Carbon dioxide storage using enhanced oil recovery (CO2‑EOR). This International Standard provides guidance for demonstrating safe, long‑term containment of CO2 injected as part of CO2‑EOR operations and for quantifying the amount of CO2 that can be considered stored in association with such projects.

Abstract

ISO 27916:2019 specifies principles, boundaries and requirements for quantification and reporting of CO2 stored when CO2 is injected to enhance hydrocarbon recovery (CO2‑EOR). It addresses applicability, project boundaries (the EOR complex and associated leakage pathways), optional allocation procedures to estimate the anthropogenic portion of stored CO2, and explicit exclusions such as lifecycle emissions and non‑injection storage techniques. The document is intended to support consistent, auditable storage claims for CO2‑EOR projects.

Scope

Applies to CO2 injected in enhanced oil and hydrocarbon recovery operations (CO2‑EOR) where project proponents seek to quantify CO2 that is safely stored long‑term in association with the CO2‑EOR project. The standard defines the conceptual project boundary (on‑site containment, leakage pathways and on‑site losses) and notes exclusions including CO2 storage in reservoirs where no hydrocarbon production is anticipated, above‑ground storage, buffer/seasonal storage, lifecycle emissions (capture/transport onsite combustion) and greenhouse gases other than CO2. Optional allocation methods are included to estimate the anthropogenic portion of stored CO2 when non‑anthropogenic CO2 sources are present.

Key topics and requirements

• Definition of the CO2‑EOR project boundary and the components to be included when quantifying stored CO2 (on‑site containment, leakage pathways, operational losses).
• Requirements and guidance for quantifying CO2 stored in association with CO2‑EOR operations, including optional allocation approaches for anthropogenic CO2.
• Explicit exclusions (lifecycle emissions, non‑injection storage, above‑ground storage, other GHGs) and scope limitations.
• Documentation and record‑keeping to support storage claims and periodic verification.
• Monitoring, measurement and reporting basics to support quantification and verification of storage associated with CO2‑EOR projects.
• Alignment with the ISO/TC 265 series on CO2 capture, transport and storage to ensure consistency with related guidance (for example geological storage and quantification/verification guidance in the 279xx family).

Typical use and users

Used by CO2‑EOR project developers, oil and gas operators implementing CO2 injection, CCS project managers, regulators and permitting authorities, verification and audit bodies, consultants and technical experts preparing project documentation, and researchers/academics working on CO2 storage measurement, reporting and verification. The standard supports stakeholders who need a consistent, auditable basis for claiming and reporting CO2 stored in association with EOR operations.
