    摘要： The present invention provides a steam-based method and system for recovering and processing a hydrocarbon mixture from a subterranean formation. The method comprises: (i) injecting steam into said formation to mobilise said hydrocarbon mixture; (ii) recovering said mobilised hydrocarbon mixture, wherein said mobilised hydrocarbon mixture comprises water and hydrocarbon; (iii) separating said hydrocarbon mixture to produce separated water and separated hydrocarbon, wherein a diluent is added to said mobilised hydrocarbon mixture prior to said separation; (iv) deasphalting said separated hydrocarbon to produce a deasphalted hydrocarbon and asphaltenes; (v) combusting said asphaltenes in an oxycombustion process to generate steam and/or energy and C02; and (vi) injecting said steam produced in step (v) into said formation and/or applying said energy produced in step (v) to generate steam and injecting said steam into said formation; wherein said method is at least partially self-sufficient in terms of steam generation and said method is at least partially self-sufficient in terms of diluent.
