CO 2 foam for enhanced oil‐recovery applications has been traditionally used in order to address mobilitycontrol problems that occur during CO 2 flooding. However, the supercritical CO 2 foam generated by surfactant has a few shortcomings. The image shows CO 2 foam generated by PECNP‐surfactant (left), PEI surfactant (middle), and surfactant itself (right) interacting with Mississippian crude oil. The foam is injected from the top of the tube. The picture is taken after a minute of contact between the foam and the crude oil. The PECNP system is proven to make CO 2 foam more stable in the presence of crude oil. (DOI: 10.1002/app.44491 )
