A method of recovering a hydrocarbon mixture from a subterranean formation

摘要

The present invention provides a method of recovering a hydrocarbon mixture from a subterranean formation comprising: (i) injecting an oxygen-rich gas into said formation; (ii) combusting said oxygen-rich gas in said formation thereby heating and reducing the viscosity of said hydrocarbon mixture and generating CO2-rich gas; (iii) recovering said heated hydrocarbon; and (iv) capturing at least a portion of CO2 from said CO2-rich gas.
