本文件: 以最大限度地降低二氧化碳损失风险的方式制定二氧化碳流地质储存要求； 适用于渗透性和多孔性地质地层内的陆上和海上地质储存，包括碳氢化合物储层，其中没有为了提高碳氢化合物产量而注入CO2流； 包括与场地筛选和可行性调查、表征、设计和开发、存储项目运营以及项目终止准备相关的活动； 认识到每个地点的地质特征、物理边界、管理、内在技术风险和不确定性对于每个项目来说可能是独特的，内在技术风险和不确定性将在一个地点处理-具体依据； 提供综合项目管理的要求，包括二氧化碳流地质储存特有的风险管理要素；和 建立量化地质封存项目封存在封存单元中的二氧化碳净质量的方法。 图1说明了本文档的局限性。 本文件不适用于: 在罐中或通过其他方式临时储存； 终止后阶段； 注入CO2以提高烃的产量或用于与CO2-EOR相关的储存； 处置被视为CO2流一部分的其他酸性气体； 处置废物和为处置目的而添加的其他物质；或者 使用任何形式的埋地容器的地下储存。 如果储存装置生产商业数量的碳氢化合物，则储存项目超出了本文件的范围，ISO 27916适用于CO2储存。在储存装置的所有碳氢化合物生产停止后，与CO2-EOR一起储存CO2的CO2-EOR项目可以过渡到根据本文件运行。

This document:

1. establishes requirements for the geological storage of CO2 streams in a way that minimizes risk of CO2 losses;
2. is applicable for both onshore and offshore geological storage within permeable and porous geological strata including hydrocarbon reservoirs where a CO2 stream is not being injected for the purpose of enhancing hydrocarbon production;
3. includes activities associated with site screening and feasibility investigation, characterization, design and development, operation of storage projects, and preparation for project termination;
4. recognizes that the geological characteristics, physical boundaries, management, intrinsic technical risk and uncertainties, of each site are likely to be unique for each project and that intrinsic technical risk and uncertainty will be dealt with on a site-specific basis;
5.  provides requirements for integrated project management, including elements of risk management unique to the geological storage of CO2 streams; and
6. establishes a methodology for quantifying the net mass of CO2 that geological storage projects store in storage unit(s).

Figure 1 illustrates the limits of this document.

This document does not apply to:

1. temporary storage in tanks or by other means;
2. the post-termination phase;
3. injection of CO2 for enhancing production of hydrocarbons or for storage associated with CO2-EOR;
4. disposal of other acid gases except as considered part of the CO2 stream;
5. disposal of waste and other matter added for purpose of disposal; or
6. underground storage using any form of buried container.

If production of hydrocarbons in commercial quantities occurs from the storage unit(s), the storage project is outside of the scope of this document and ISO 27916 applies to CO2 storage. A CO2-EOR project that has stored CO2 in association with CO2-EOR can transition to operate under this document after all production of hydrocarbons from the storage unit(s) has ceased.
