Abstract
A process for preparation of synthetic crude from a deposit of heavy crude, comprises: (a) the extraction of heavy crude by technology using steam; (b) the separation of crude extract and water; (c) the separation of crude into at least one light fraction and one heavy fraction; (d) the conversion of the heavy fraction of separation into a lighter product, said converted product, and a residue; (e) optionally, the partial or total hydrotreatment of the converted product and/or the light fraction (or fractions) obtained during the separation c), (f) the combustion and/or gasification of the conversion residue; the converted product and the light fraction (or fractions) for separation, optionally having been subjected to a hydrotreatment e), constituting the synthetic crude; said combustion allowing the generation of steam and/or electricity and said gasification allowing the generation of hydrogen; the steam and/or electricity thus generated being used for the extraction a) and/or the electricity and/or hydrogen thus generated being used for the conversion d) and/or the hydrotreatment e).
