二氧化碳的捕获和地下储存被广泛认为是任何战略的必要组成部分，以尽量减少和控制全球平均气温的持续上升。现有的石油和天然气储层可以重新用于碳储存，为工业规模实施碳储存所需的大量地下储存空间提供了很大一部分。枯竭储层中的碳捕获和储存旨在确保地下遏制，既满足安全考虑，又提供遏制将在必要的时间尺度内持续的信心。需要解决的其他技术问题包括意外地下事件的风险，如诱发地震活动。最大限度地减少这些风险是建立对CCS技术的信心的关键，无论是在融资/责任方面，还是在发展和保持公众接受度方面。这些因素对于涉及枯竭油气藏的二氧化碳捕获和储存项目可能特别重要，因为在这些项目中还必须考虑到生产活动的机械影响。鉴于盖层行为在这方面的重要性，一些以前发表的地质力学盖层研究枯竭油气藏确定和审查，包括实验和数值研究的14 CCS试点地点在枯竭油气藏，在七个国家（阿尔及利亚，澳大利亚，芬兰，法国，德国，荷兰，挪威，英国）。特别强调收集的数据的数量和类型、用于进行地质力学分析的数学方法和代码以及地质力学方面与公众感知之间的关系。合理的地质力学评估有助于最大限度地降低运营和财务/责任风险，并认真认识公众看法的影响，这是有助于在枯竭油气藏中成功开发CCS项目的两个关键因素。
Capture and subsurface storage of CO2is widely viewed as being a necessary component of any strategy to minimise and control the continued increase in average global temperatures. Existing oil and gas reservoirs can be re-used for carbon storage, providing a substantial fraction of the vast amounts of subsurface storage space that will be required for the implementation of carbon storage at an industrial scale. Carbon capture and storage (CCS) in depleted reservoirs aims to ensure subsurface containment, both to satisfy safety considerations, and to provide confidence that the containment will continue over the necessary timescales. Other technical issues that need to be addressed include the risk of unintended subsurface events, such as induced seismicity. Minimisation of these risks is key to building confidence in CCS technology, both in relation to financing/liability, and the development and maintenance of public acceptance. These factors may be of particular importance with regard to CCS projects involving depleted hydrocarbon reservoirs, where the mechanical effects of production activities must also be considered. Given the importance of caprock behaviour in this context, several previously published geomechanical caprock studies of depleted hydrocarbon reservoirs are identified and reviewed, comprising experimental and numerical studies of fourteen CCS pilot sites in depleted hydrocarbon reservoirs, in seven countries (Algeria, Australia, Finland, France, Germany, Netherlands, Norway, UK). Particular emphasis is placed on the amount and types of data collected, the mathematical methods and codes used to conduct geomechanical analysis, and the relationship between geomechanical aspects and public perception. Sound geomechanical assessment, acting to help minimise operational and financial/liability risks, and the careful recognition of the impact of public perception are two key factors that can contribute to the development of a successful CCS project in a depleted hydrocarbon reservoir.
