Summary:The prospects for using dimethyl ether (DME) for enhancing the oil recovery are analyzed. The analysis is based on the results of physical (laboratory) and mathematical modeling of this technology. The mechanism of intensifying the oil extraction and enhancing the oil recovery by injecting dimethyl ether into a reservoir is considered. The major factors influencing the distribution ratio of DME between the oil and aqueous phases are evaluated. The advantages of injecting DME into a reservoir prior to injecting hydrocarbon gases and carbon dioxide are revealed. Combined technologies for enhancing the oil recovery, involving injection of DME, carbon dioxide, polymer solutions, and steam into a reservoir are analyzed. The possibility of using DME for separation of oily sludges is briefly discussed.
