A recent technology innovation is boosting potentials of chemical enhanced oil recover y（EOR） application to harsher field conditions, whereas it was possible for limited conditions under the past classic EOR screening criteria（Taber. et al. 1997）. To proceed with such a chemical EOR application, nobody doubts an importance of water management; however, most of the technical discussions focus on injection while lesser on production. Therefore, this paper recaps the recent innovation of chemical EOR and reminds the importance of water management from a viewpoint of production treatment in particular for realistic operatability. Finally, our current progress of technology acquisition is introduced with a brief roadmap plan.
