摘要
The present invention relates to a method of preparing synthetic crude oil from a heavy crude reservoir, comprising: (a) extracting the heavy crude oil using a steam technology; (b) separating the crude extracted and the water; (c) separating the crude into at least one light cut and one heavy cut; (d) converting said heavy cut to a lighter product and a residue; (e) optionally, partially or totally hydroprocessing the converted product and/or the light cut(s) obtained upon separation (c); (f) burning and/or gasifying the conversion residue in the presence of metal oxides in at least one chemical looping cycle producing CO2-concentrated fumes in order to allow CO2 capture, the optionally hydroprocessed converted product and light separation cut(s) making up the synthetic crude oil, said combustion allowing to generate steam and/or electricity, and said gasification allowing to generate hydrogen, the steam and/or the electricity thus generated being used for extraction (a), and/or the electricity and/or the hydrogen thus generated being used for conversion (d) and/or hydroprocessing (e).
