数值模拟可能是唯一可用的工具，以评估和预测二氧化碳注入深层地质储层，特别是在枯竭的油气田的命运。在这里，我们提出了一种方法，其目的是评估地质泄漏风险的地下储存使用枯竭油田作为主机水库。该方法结合流域和水库规模的模拟，以确定存储的效率。该方法旨在研究注入CO2后的储层，并且不考虑任何CO2注入期。该方法被应用到四十年代场（北海），二氧化碳的行为进行了模拟为1000年的时间段。我们的研究结果表明，当地的地质条件是相当有利的CO2封存。CO2的可能停留时间将在数千年的量级，因此，这种地质枯竭的油气田储存可能是长期CO2封存的良好替代方案。此外，这项工作的结果可以帮助建立标准，以确定其他成熟的油气田，旨在封存二氧化碳。
Numerical modelling is likely the only available tool to evaluate and predict the fate of CO2 injected in deep geological reservoirs, and particularly in depleted hydrocarbon fields. Here we present a methodology which aims at evaluating the geological leaking risk of an underground storage using a depleted oil field as the host reservoir. The methodology combines basin and reservoir scale simulations to determine the efficiency of the storage. The approach was designed for the study of the reservoir after the injection of CO2 and then does not take into account any CO2 injection period. The approach was applied to the Forties field (North Sea) for which CO2 behaviour was simulated for a 1000 y time period. Our findings suggest that local geological conditions are quite favourable for CO2 sequestration. Possible residence time of CO2 will be in the order of thousands of years and, thus such geological depleted hydrocarbon fields storage is probably a good alternative for a long term CO2 sequestration. Additionally, results of this work can help to establish criteria to identify other mature hydrocarbon fields aimed for CO2 sequestration.
