Carbon dioxide (CO₂) injection is implemented into the reservoir to further improve the oil production efficiency, by mixing with oil at reservoir condition, and becomes miscible. The miscibility affects the oil to become swelled and less viscous and thus easily flow through the reservoir. Most of the (CO₂) EOR projects has higher recovery factor in miscible condition. Therefore, this article aims to determine the effects of the miscible (CO₂) injection on production recovery in the Cornea Field. The Cornea Field is located in Browse Basin, Western Australia. It is a simple trap structure which is elongated and formed by unfaulted drape anticline over an eroded high basement. The importance of this research is that (CO₂) injection has not been implemented in the Cornea Field since it is a complex reservoir. However, research showed that there was a high potential production recovery in this field. Therefore, research needs to be conducted to determine the effectiveness of the (CO₂) injection on production recovery in this field. The model was validated, by comparing MMP obtained from the simulation model and correlation methods. The MMP of this reservoir is above 38 Bar. Sensitivity analysis on reservoir pressure, reservoir temperature and (CO₂) injection rate was investigated. Oil production increases with the increase in reservoir pressure and reservoir temperature. As the (CO₂) injection rate increases, oil production also increased. From the result, hence, this study should contribute to the knowledge gap in Cornea Field.

将二氧化碳(CO ₂ )注入油藏，通过在油藏条件下与油混合，进一步提高采油效率，使其混溶。混溶性使油变得膨胀且粘性降低，因此容易流过油藏。大多数（CO ₂）EOR 项目在混相条件下具有更高的采收率。因此，本文旨在确定混相（CO ₂）注入对角膜油田生产恢复的影响。角膜油田位于西澳大利亚州的 Browse Basin。它是一个简单的圈闭结构，由无断层的悬垂背斜在侵蚀的高基底上拉长形成。这项研究的重要性在于（CO ₂) 注入尚未在角膜油田实施，因为它是一个复杂的储层。然而，研究表明，该领域具有很高的生产恢复潜力。因此，需要进行研究以确定（CO ₂）注入对该领域生产恢复的有效性。通过比较从模拟模型和相关方法获得的MMP，对该模型进行了验证。该储层的 MMP 高于 38 Bar。研究了储层压力、储层温度和（CO ₂）注入速率的敏感性分析。石油产量随着油藏压力和油藏温度的增加而增加。由于 (CO ₂) 注入量增加，石油产量也增加。因此，从结果来看，这项研究应该有助于弥补角膜领域的知识差距。
