Abstract
• A novel CFD-based approach is proposed for flow pattern identification in CO 2 -EOR production wells. • A pressure-drop prediction model is established by integrating an interphase mass-transfer mechanism. • Sensitivity analysis shows that gas–liquid ratio and flow velocity dominate flow pattern transitions. • Fluid properties govern pressure gradient: high water cut increases loss, while higher CO 2 reduces pressure drop. Understanding the multiphase transport behavior in production wells is critical for the safety and efficiency of Carbon Capture, Utilization, and Storage (CCUS) systems. In this study, a wellbore numerical model was established using computational fluid dynamics (CFD), incorporating the CO…
