Oil Displacement from a Porous Medium with the Aid of a Graphite Suspension

Resumo

It has been found that N aqueous suspension of planar graphite nanoparticles exhibits properties of displacement fluid at the oil–water interface. Experiments with the Hele–Shaw cell showed that the process of oil displacement from the interface is not accompanied by the formation of viscous “fingers” as a result of development of instability at the oil–water interface.
