Geological storage of CO₂ in deep saline aquifers mitigates atmospheric emissions. In situ storage is facilitated by several trapping mechanisms including residual trapping, which plays a major role in the containment of CO₂. Understanding the underlying mechanisms of residual trapping is crucial for planning storage projects. Of special interest is the relationship between the initial and residual CO₂ saturations—the so-called IR curve, needed for predictive macroscopic-scale simulations.

CO ₂在深部咸水层中的地质储存可减轻大气排放。多种捕集机制促进了原位储存，包括残余捕集，其在 CO ₂的遏制中起主要作用。了解残留捕获的潜在机制对于规划存储项目至关重要。特别令人感兴趣的是初始和残余 CO ₂饱和度之间的关系——即所谓的 IR 曲线，用于预测性宏观尺度模拟。
