Abstract
An efficient and cost-effective process of carbon dioxide recycling in enhanced oil recovery wells or in fracturing wells is provided. The process comprises recovering a hydrocarbon enriched stream of condensed carbon dioxide from and enhanced oil recovery (EOR) well or a fracturing well; adding to said stream one or more thickeners; and directing the thickened stream to the EOR well or fracturing well for recycled usage in EOR.
