Carbon dioxide (CO2) is injected into reservoirs for enhanced oil recovery worldwide, which is an important technology to reduce carbon emissions from burning and consumption of fossil fuels. However, it is difficult to control the mobility of carbon dioxide in the formation, thus limiting its extensive utilization. In this work, particulate matter (PM) from flue gas was used to obtain an interfacial armored foam for controlling the CO2 mobility in porous media.

Carbon dioxide (CO2) foam flooding is a promising carbon capture, utilization, and storage technology that is often used for enhanced oil recovery (EOR). However, the instability of foam and low displacement efficiency restrict its efficient utilization. In this work, the microflow behavior and the EOR performance of aqueous CO2 foam stabilized by particulate matter (PM) from coal combustion were systematically studied using a micromodel with etched porous media.
