<p>A method and system for recovering and processing a hydrocarbon mixture from a subterranean formation involves: (i) mobilising said hydrocarbon mixture; (ii) recovering said mobilized hydrocarbon mixture; (iii) deasphalting said recovered hydrocarbon mixture to produce deasphalted hydrocarbon and asphaltenes; (iv) gasifying said asphaltenes in a gasifier to generate hydrogen, steam and/or energy and CO2; and (v) upgrading said deasphalted hydrocarbon by hydrogen addition to produce upgraded hydrocarbon, wherein said method is at least partially self-sufficient in terms of hydrogen.</p> |
