NOVELTY - The process comprises extracting heavy crude by a technology using steam, separating the crude extract and water, separating crude into light cut and heavy cut, converting the heavy cut of separation into a more light product and a residue, optionally, partially or totally hydrotreating the converted product and/or light cut obtained during separation, and combusting and/or gasifying residue producing smoke having carbon dioxide greater than 90% in the presence of metal oxide in a chemical loop cycle of the conversion for capturing carbon dioxide.    USE - The process is useful for producing synthetic crude from a pool of heavy crude.    ADVANTAGE - The process ensures easy, economical and rapid production of synthetic crude from a pool of heavy crude with high quality, improved density and viscosity and less consumption of energy.    DETAILED DESCRIPTION - The process comprises extracting heavy crude by a technology using steam, separating the crude extract and water, separating crude into light cut and heavy cut, converting the heavy cut of separation into a more light product and a residue, optionally, partially or totally hydrotreating the converted product and/or light cut obtained during separation, and combusting and/or gasifying residue producing smoke having carbon dioxide greater than 90% in the presence of metal oxide in a chemical loop cycle of the conversion for capturing carbon dioxide. The chemical looping combustion is used for the generation of steam and/or electricity, and the gasification in chemical loop is used for generation of hydrogen, water vapor and/or electricity. The rate of carbon dioxide captured in the chemical loop is 90%. The conversion is carried out by coking, viscosity reduction or catalytic hydroconversion. The conversion rate is adjusted so that the combustion and chemical looping gasification is provided for generating all steam needed in the extraction or entire hydrogen required in conversion and optionally in hydroprocessing. The conversion is thermal conversion or catalytic hydroconversion. The extraction is done by a production process assisted by continuous injection of steam or steam assisted gravity drainage, or production process assisted by cyclic steam injection or cyclic steam stimulation. The heavy crude has a viscosity of greater than 10000 CPO and a density of lower than 12 degrees API. The obtained synthetic crude has a density of 0.94 in the standard conditions and 19 degrees API, and viscosity of less than 350 sct at 4 degrees C.
