Title:
METHOD FOR PRODUCING VISCOUS HYDROCARBON USING STEAM AND CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO2008045408
Kind Code:
B1
Abstract:
A downhole burner is used for producing heavy-oil formations. Hydrogen, oxygen, and steam are pumped by separate conduits to the burner, which burns at least part of the hydrogen and forces the combustion products out into the earth formation. The steam cools the burner and becomes superheated steam, which is injected along with the combustion products into the earth formation. Carbon dioxide is also pumped down the well and injected into the formation.
