Pore-scale flow simulation of supercritical CO and oil flow for simultaneous CO geo-sequestration and enhanced oil recovery.

Recently, carbon capture, utilization, and storage (CCUS) with enhanced oil recovery (EOR) have gained a significant traction in an attempt to reduce greenhouse gas emissions. Information on pore-scale CO fluid behavior is vital for efficient geo-sequestration and EOR. This study scrutinizes the behavior of supercritical CO (sc-CO) under different reservoir temperature and pressure conditions through computational fluid dynamics (CFD) analysis, applying it to light and heavy crude oil reservoirs.
