📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではCCUS/CO2-EORはGX推進戦略やJOGMEC主導の適地調査と連動するが、本論文は油層工学的なMMP評価が中心で、国内の制度的・投資家的文脈との直接の接点は限定的。それでもCCUS実装の技術的基礎として日本のCCUS関係者には参考価値がある。
In the global GX context
Globally, CCUS is central to net-zero pathways and transition finance, and reliable MMP prediction underpins the technical and economic feasibility of CO2-EOR/storage projects. This review supports engineering due diligence for CCUS project design, though it sits upstream of disclosure frameworks like TCFD/ISSB.

📄 Abstract(原文)
In the context of the rapid advancement of carbon capture, utilization and storage (CCUS) technologies, CO2 flooding has garnered considerable attention owing to its dual benefits in boosting oil recovery and enabling geological carbon sequestration. Maximum oil displacement efficiency can be achieved when CO2 achieves miscibility with crude oil. Minimum miscibility pressure (MMP) is a pivotal criterion for determining oil-gas miscibility. Field operations demonstrate that the miscibility state between CO2 and crude oil varies spatially and temporally within reservoirs during flooding processes, which manifests the dynamic evolution of MMP. Precise determination of MMP has remained a key research focus. This paper reviews experimental protocols and theoretical prediction models for MMP, and clarifies the potential of various approaches for studying MMP evolutionary behavior. The underlying mechanisms and evolutionary rules of MMP are elaborated in terms of component interaction, reservoir conditions and displacement parameters. Meanwhile, practical MMP applications are analyzed based on two representative CO2 flooding pilot projects. Finally, current research outcomes are concluded and prospective research trends are proposed. This Review systematically demonstrates that MMP dynamic evolution arises from the coupling effect of multiple factors, providing essential theoretical insights and technical guidance for optimizing project design and managing pressure dynamics in CO2 miscible flooding development.
