A METHOD AND A SYSTEM OF RECOVERING AND PROCESSING A HYDROCARBON MIXTURE FROM A SUBTERRANEAN FORMATION

摘要

The present invention relates to a method and system for recovering and processing a hydrocarbon mixture from a subterranean formation. The method comprises: (i) mobilising said hydrocarbon mixture; (ii) recovering said mobilised hydrocarbon mixture; (iii) coking said recovered hydrocarbon mixture to produce decoked hydrocarbon and coke; (iv) combusting said coke to generate steam and/or energy and CO2; (v) upgrading said decoked hydrocarbon by hydrogen addition to produce upgraded hydrocarbon; and (v) adding a diluent to the decoked hydrocarbon prior to upgrading and/or adding a diluent to the upgraded hydrocarbon; wherein said method is at least partially self-sufficient in terms of steam and/or energy and diluent.
