The global warming crisis, traceable to the rise in greenhouse gas emissions, has called for more proactive measures to curb the emission levels. To this effect, several technologies have been suggested. Out of the lot, carbon capture, utilization, and storage have been identified as one of the most feasible and pragmatic methods. This is partly because the concept, technical resources, and facilities are transferable from CO injection and enhanced oil recovery applications. For this reason, studies centered around CO conformance control for subsurface storage have been conducted. Also, reviews on the classification and description of chemical materials utilized for the conformance control have been published. With the limitations of these materials in mind, this review extends the types of sealants that can be applied for CO entrapment in subsurface geologic formations. The group of gelants that generally fall under multicomponent polymer systems and viscoelastic fluids was evaluated. The review describes their properties, behavior, response to CO, and other unique features that make them suitable to be considered for reservoir conformance control purposes. Based on the review, recommendations for future studies on these novel materials were given.
全球变暖危机可追溯到温室气体排放的增加，这就需要采取更积极的措施来控制排放水平。为此，人们提出了几种技术。其中，碳捕获、利用和封存已被确定为最可行和务实的方法之一。部分原因是该概念、技术资源和设施可从二氧化碳注入和强化采油应用中转移过来。因此，已经开展了围绕地下储存二氧化碳一致性控制的研究。此外，也发表了关于用于一致性控制的化学材料的分类和描述的综述。考虑到这些材料的局限性，本综述扩展了可用于在地下地质构造中捕获二氧化碳的密封剂类型。对通常属于多组分聚合物体系和粘弹性流体的凝胶剂组进行了评估。该综述描述了它们的特性、行为、对二氧化碳的反应以及其他使其适合用于储层一致性控制目的的独特特征。基于该综述，给出了关于这些新型材料未来研究的建议。
