DEMULSIFICATION IN EOR OPERATIONS: CURRENT AND FUTURE DIRECTIONS

Demulsification or emulsion breaking is necessary in many practical applications such as the petroleum industry, coating, painting, and waste water treatment in environmental technology. Breaking emulsion is a critical step in the oil production process for meeting production targets, adhering to commercial crude oil specifications and yielding cleaner produced water for discharge or reinjection, as well. Determining the most effective solution to separating emulsions is one of the most difficult projects a service company faces. The best quality oil is oil with the lowest basis sediment and water (BS and W) and low API gravity values. In this paper the most important parameters involved in this process have been considered by details
