Abstract:
A process and a system for enhancing recovery of oil from an oil-bearing formation are provided in which water having a total dissolved solids content is filtered to remove some solids in a filter assembly, the filtered water is treated to remove some ions in a capacitive deionization assembly, and the filtered deionized water is injected into the oil-bearing formation to mobilize crude oil and enhance oil recovery from the formation.
