Applications of carbon dioxide for heavy oil enhanced oil recovery via vapour extraction process

Recently production of heavy oil and bitumen is become an interesting subject for petroleum engineers to enhance oil recovery from these reservoirs. Vapor extraction (VAPEX) is a promising enhanced oil recovery (EOR) technique that has not been performed in an oil field. Infeasibility of VAPEX proce...

Vapor extraction (VAPEX) is a promising enhanced oil recovery (EOR) technique that has not been performed in an oil field.
