Steam self sufficient recovery of heavy hydrocarbons including deasphalting

A method and system for recovering and processing a hydrocarbon mixture from a subterranean formation is at least partially self-sufficient in terms of steam generation and involves: (i) injecting steam into said formation to mobilise said hydrocarbon mixture (ii) recovering said mobilised hydrocarbon mixture; (iii) deasphalting said recovered hydrocarbon mixture to produce a deasphalted hydrocarbon and asphaltenes; (iv) combusting said asphaltenes in an oxy-combustion process to generate steam and/or energy and CO2; and (v) injecting said steam produced in step (iv) into said formation and/or applying said energy produced in step (iv) to generate steam and injecting said steam into said formation. The method may also be self sufficient in terms of water or diluent.
