    Abstract: After secondary flooding, the process of injecting chemicals such as Nanoparticles into the reservoir in order to release and produce the trapped oil in that reservoir is called chemical flooding enhanced oil recovery (CEOR). The trapped oil is due to some forces such as viscous, gravity and capillary forces. Several reservoir problems have been so... Show More
