As far as I am concerned, 2018 became the year I dealt with some aspect of enhanced oil recovery (EOR) every week. I had noticed that, in recent years, interest in bringing EOR to field operations had been growing everywhere. As operators and asset owners worked continually to increase efficiency in oil production, they all realized that part of efficiency improvement is increasing recovery factors. Everybody now is extremely focused on recovering more from the reservoirs they have. Of course, limited exploration and maturing fields are some of the motives behind that new attitude.
